1. Introduction
Hello everybody, my name is Niko and I'm an avid DCS fan since the first LOMAC release. Professionally I am an R&D Chief over at EK Water Blocks (EKWB), a Slovenian liquid cooling gear manufacturer. My current hobbies are mountaineering, alpine climbing and still - to some extent - extreme overclocking and benchmarking. In my best days (early 2010s) I used to be top 20 worldwide in the Hwbot extreme overclocking league and top 10 in the hardware master league.

I'm not participating much in the extreme OC anymore but the benchmarking and tweaking spirit is still well present. Instead of extreme overclocking I am now enjoying exploring, learning and building 24/7 stable price/performance and performance/watt setups. Dry and warm winter this year allows me to spend more time data mining as the winter climbing season is still not here.
2. The purpose of this thread
I would like to present you some data mining I have been doing whilst preparing my computer for the simpit I am building. I have an access to plethora of GPUs and system platforms as well and I intend to exploit this for the benefit of the DCS community.

My goal is to show the bottleneck effect of components (GPU, CPU, RAM) on the performance of the DCS 1.5.x (currently 1.5.2).

At the end of the day I hope this thread will be a good buying/upgrading guide for the DCS community. Nothing is more frustrating than buying HW upgrades which yield no performance gain...
3. What is to be tested?
This test will focus on the following:

1. CPU core count impact on FPS
2. CPU core frequency impact on FPS (using Intel Haswell-E)
3. CPU core architecture impact on FPS


4. DRAM frequency impact on FPS (using Intel Haswell-E and DDR4)


5. Display resolution impact on FPS (using Radeon R9 Nano)
6. Multi-monitor gaming performance analysis (using GeForce GTX Titan X)
7. VR resolution gaming performance analysis (using GeForce GTX 960 and -980 Ti)
8. GPU architecture impact on FPS
Open the 'spoiler' below for explanation:

4. Testing methodology explained
- The performance is tested using using DCS: Flaming Cliffs 3 by running a pre-recorded F-15C flight (replay) on a fixed graphics settings
- Pre-recorded F-15C flight is a F-15C quick mission - it consists of BVR with 4 enemy airplanes, merge with remaining MiG-23 and close-combat dogfight (guns and missiles) with MiG-23 until the end of the track.
- Different GPUs are tested using the same pre-recorded flight at three different resolutions: FHD, WQHD and 4K
- Fraps software will log a session FPS for a total duration of the benchmark run (finite time)
- Every test setup is equipped with adequate (16GB) quantity of system DRAM to prevent disk swapping
- Each system runs Windows 10 Pro x64 and the latest graphics card drivers
- We are not solely focusing on minimum-, maximum- and average FPS but also the percentage of time FPS dipped under certain threshold

Image quality as tested (4K):


- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -


What have we learned so far (tl;dr):
Compiled list of lessions learned:
Quote:
1. If budget allows - get a fast (overclockable) quad-core CPU! Yes, DCS scales great up to 4 cores!
2. Overclock your CPU: Frequency is the king! Most of the GPU performance will be CPU frequency bound.
3. Skylake rocks this game, the 6700K or alternatively 6600K is the best choice at the moment. Get the lowest bin Core i5 CPU and overclock it via BCLK on a supported Z170 motherboard if budget it tight!
4. Faster memory yields noticable performance gains, especially in the minimum FPS range
5. Flying in 4K on PC: On AMD R9 series - make sure to use DisplayPort (DP) 1.2 for 4K@60Hz - do not use HDMI as HDMI 1.4 isn't cutting it (only 30Hz refresh rate). On NVIDIA GTX 9xx series use either DP1.2 or HDMI (supports HDMI 2.0).
6. Flying in 4K on TV: AMD is currently not a good choice for 'cheap' TV 4K. The problem is that these R9 200/300/Fury/Nano cards can only put out 4K@30Hz over HDMI 1.4. The only way to get 4K@60Hz on current gen AMD is to use DisplayPort (DP) video outputs, which works great - 4K PC monitors with DP video inputs are readily available, however DP 4K TVs are not. If your 4K TV only supports HDMI it's better if you get NVIDIA. Alternatively you can purchase DP 1.2 to HDMI 2.0 adapter which bypasses all of the aforementioned issues. At the time of writing (Jan 2016) the cheapest 55" 4K@60Hz TVs with DP video inputs are still 8-10x more expensive than their HDMI 2.0 counterparts.
7. Overclocking of the GPUs tested yield noticable gains starting with WQHD resolution. Lower performance GPUs than the ones tested (e.g. GTX 750) will benefit from GPU overclocking even in low resolutions.
8. It is safe to say GTX 960 is currently the price/performance king for playing DCS at WQHD (2560x1440) while GTX 970 is the P/P king for playing FCS in 4K. For playing DCS at FHD resolution an AMD Radeon R7 370 (basically only about 10-15% slower than R9 270X) or NVIDIA GeForce GTX 950 will be great. If money is tight consider higher-end last gen GPUs.
9. CrossFireX work and scales nicely but seem to cause micro-stuttering. The latter can be remedied by setting MODEL VISIBILITY to off (however I haven't found that function in settings as of version 1.5.2).
10. Multi-monitor WALL setup - with 'regular' FOV (field-of-view, e.g. "1 Monitor" preset within the game settings) - performs equally good as the single-monitor setup at comparable (total) resolution. Therefore it's possible to build a cheap large, high-resolution screen out of smaller panels.
11. Multi-monitor BOX setup - with high FOV (field-of-view, e.g. "3 Monitor" preset within the game settings) - heavily taxes the FPS, regardless of your graphics card, most likely because of the DCS 1.5 engine limitation. A workaround is to set the MEDIUM graphics preset to enjoy high FPS.
12. VR setup (2160x120 - "Stereo" mode) is - despite the low resolution - very demanding on this game and one needs to resort to lowering quality settings in order to achieve 75FPS+. A high end and a low end GPU perform pretty exactly the same, a sign of engine bottleneck.

5. Testing results

5.1.
CPU core count impact on FPS
The purpose of this test is to test out the impact of the CPU core count on the general FPS performance. The core count tested covers most of the currently available CPUs. Single core performance is added for reference.

HW setup configuration for this test:
- CPU: Intel Core i7 5820K @ 4GHz core / 3.3GHz uncore
- MB: ASRock X99E-ITX/ac
- RAM: 2x8GB DDR4-3200 C16 18-18-36 1T
- GPU: AMD Radeon R9 Nano (+25% power target)
- Drive: 2x 256GB Crucial BX100 @ RAID0
- OS: Windows 10 Pro x64
- Cooling: EKWB custom loop liquid cooling (GPU, CPU)

Game settings:
Spoiler:


Results:







CPU core count impact result analysis:
- Please allow for +/- 2% result accuracy. The overlapping graphs peak/dips are always a good sign of a reliable data aquisition.
- CPU core count effect lessens after 4 cores. It appears the performance peak is reached when utilizing 4 cores. Utilizing more than 4 cores gains to further performance boost
- Average time for the simulation when FPS is lower than 60, varies greatly even though the average FPS appears to be high for smooth gameplay when running the game on a single thread (core).


5.2.
CPU core frequency impact on FPS
The purpose of this test is to test out the impact of the CPU core frequency on the general FPS performance. The frequencies tested range from 2.5- to 4.5GHz, which should cover the sprectrum from the higher-end notebooks to decently overclocked desktop CPU.

HW setup configuration for this test:
- CPU: Intel Core i7 5820K @ 2.5-4.5GHz core / 3.0-3.3GHz uncore
- MB: ASRock X99E-ITX/ac
- RAM: 2x8GB DDR4-3200 C16 18-18-36 1T
- GPU: AMD Radeon R9 Nano (+25% power target)
- Drive: 2x 256GB Crucial BX100 @ RAID0
- OS: Windows 10 Pro x64
- Cooling: EKWB custom loop liquid cooling (GPU, CPU)

Game settings:
Spoiler:


Results:






CPU Frequency Impact result analysis:
- Please allow for +/- 2% result accuracy. The overlapping graphs peak/dips are always a good sign of a reliable data aquisition.
- Performance of the DCS still greatly rely on the CPU frequency and scales almost linearly.
- Overclocking proves beneficial and seems to be the great choice to enhance performance of the system w/o additional costs (providing that your cooling system can handle it)
- 2.5GHz 'underclock' simulates a higher-end mobile CPU performance (i.e. Haswell or Skylake QH CPU).

5.3 CPU architecture impact on the FPS:
The purpose of this test is to test out the impact of the different CPU architecture on the general FPS performance. I have selected the FHD resolution as a starting point, which is in my books considered a 'low' resolution. CPU tests are always done on 'low' resolutions to exclude the possible GPU bottleneck.

This was one of the most time consuming tests which I don't want to repeat ever again.

I hadn't had the chance to test FX 8350 yet, but hopefully I will be able to do so in the upcoming weeks. I guess it will do around ~ 65FPS on average.

Test systems:
- CPU: (as listed before)
- MB:
  • Gigabyte GA-990FXA-UD7
  • Gigabyte F2A88XN Wifi
  • ASUS ROG Maximus IV Gene-Z
  • ASRock Z77-Extreme4
  • ASUS ROG Maximus VII Gene
  • MSI B150 Gaming Night Elf
  • ASUS ROG Maximus VIII Extreme
- RAM:
  • 4x4GB DDR3-2133 C10 12-12-28 1T @ 1.35V
  • 2x8GB DDR4-2800 CL15 16-16-34 1T
  • 2x8GB DDR4-2133 CL15 15-15-31 2T
- GPU: MSI GeForce GTX 970 Gaming 4G
- Drive: 128GB Crucial BX100
- OS: Windows 10 Pro x64
- Cooling: factory cooling on CPU; factory cooling on GPUs
- Monitor: Dell 2713HM
- Drivers: Nvidia 361.43


Game settings (expect for the resolution which is 1920x1080 FHD):
Spoiler:


Final results are as following:





GPU Architecture Impact result analysis:

- Please allow for +/- 2% result accuracy. The overlapping graphs peak/dips are always a good sign of a reliable data aquisition.
- Please note that Core i5 6600 setup was running on a non-overclockable B150 motherboard, thus memory ran at DDR4-2133 CL15 15-15-31 2T. Just by running it on a Z170 motherboard and cranking up the memory speed we would see up to 10FPS boost.
- Please note that Core i7 6700K setup was running using DDR4-2800 CL15 16-16-34 1T memory settings.
- Core i7 6700K stock clock is 4GHz, hence the same results for non-OC and OC test
- Broadwell with it's 128MB L4 seem to offer nice boost compared to Haswell. When set to 4GHz (which this sample did with factory voltage) it even surpases Skylake.


5.4. DRAM frequency impact on FPS
The purpose of this test is to test out the impact of the DRAM frequency on the general FPS performance. The frequencies tested ranged from DDR4-2133 to -3200, which should cover the majority of available memory kits.

HW setup configuration for this test:
- CPU: Intel Core i7 5820K @ 4.0GHz core / 3.3GHz uncore
- MB: ASRock X99E-ITX/ac
- RAM: 2x8GB DDR4 (2133 - 3200)
- GPU: AMD Radeon R9 Nano (+25% power target)
- Drive: 2x 256GB Crucial BX100 @ RAID0
- OS: Windows 10 Pro x64
- Cooling: EKWB custom loop liquid cooling (GPU, CPU)

Game settings:
Spoiler:


Results:







DRAM Frequency Impact result analysis:
- Please allow for +/- 2% result accuracy. The overlapping graphs peak/dips are always a good sign of a reliable data aquisition.
- DRAM frequency has a bigger impact on performance than anticipated but still far less than CPU core count or - more importantly - CPU frequency.
- A somewhat big performance gain is obtained when choosing DDR4-2400 memory over DDR4-2133.
- Faster memory (or memory overclocking) should always be considered as long as the price of the faster bin is reasonable.


5.5. Display resolution impact on FPS
The purpose of this test is to test out the impact of the display resolution on the general FPS performance. The display resolutions tested ranged from FHD to 4K, which should cover the sprectrum from the entry-level PC screens to latest 4K displays. I did a brief study with Radeon R9 Nano on my setup to see if what is to be expected when pushing GPUs to draw 8+ megapixels.

HW setup:
- CPU: Intel Core i7 5820K @ 4.0GHz core / 3.3GHz uncore
- MB: ASRock X99E-ITX/ac
- RAM: 2x8GB DDR4-3200 C16 18-18-36 1T
- GPU: AMD Radeon R9 Nano (+25% power target)
- Drive: 2x 256GB Crucial BX100 @ RAID0
- OS: Windows 10 Pro x64
- Cooling: EKWB custom loop liquid cooling (GPU, CPU)

HW setup configuration for this test:
- Same as above, just tested out on three different resolutions: 1920x1080 (FHD); 2560x1440 (WQHD); 3840x2160 (UHD a.k.a. 4K).

Results:








Display Resolution Impact result analysis:
- Please allow for +/- 2% result accuracy. The overlapping graphs peak/dips are always a good sign of a reliable data aquisition.
- Somewhat expected result for a high-end GPU, the R9 Nano (and alikes) really start to shine only at higher resolution. It is an total overkill for the FHD. This GPU (and alikes) is strong enough to drive single 4K monitor resolution with ease.

5.6 Multi-monitor gaming performance analysis:
The purpose of this test is to test out the impact of the multi-monitor high FOV display setup on the general FPS performance. As for the multi monitor setup I did try it out (3x FHD = 5760x1080) and was surprises how demanding this is, despide lower megapixel count (6.2MPix vs. 8.3MPix) compared to 4K. Very large FOV, which is caused with "3 Monitor" option literally drops performance to the floor.

"1 Monitor" (WALL) option works perfectly and within expectations - it
performs equally good as the single-monitor setup at comparable (total) resolution




My findings were:
- GTX 780 Ti, GTX 970 and GTX 980 Ti: they all perform pretty much exactly the same - around 38FPS (9FPS min ; 66FPS max)
- There must be a bottleneck somewhere... Not sure if it's CPU bound, GPU arch bound or DCS engine limitation.
- I tried further overclocking the CPU but didn't get much better, maybe 2.5 FPS better on average (in the from 38FPS to ~ 40FPS)
- Doesn't appear to be CPU bound, at least not frequency wise. Has to be DCS engine limitation or simply GPUs cannot cope with number of polys on the screen
- I tried GPU overclocking but also only did *maybe* 1-2FPS better on average
- I observed GPU video ram usage - on 4K it never goes above 2.8GB with general preset at High.
- I tried lowering Trees Visibility, Lowering Preload Radius, Disabling shadows and HDR: No real improvement, altogether maybe 4-5 FPS better performance on average.
- I tried "3 Monitor" option then on a single 4K resolution screen (8.3MPix image) and results we're better - around 45 FPS average (10FPS min ; 94FPS max) - but most likely due to smaller FOV. I was getting frustrated by then...

Then came the big revelation - the power draw of a system with an overclocked (1400MHz GPU Titan X) used to be up to 380W throughtout the majority of the benchmark. With 4K "3 Monitor" and everything on HIGH settings it only reaches this value for a very short period of time, otherwise it's somewhere between 230-260W. But... When main quality PRESET is set to MEDIUM the power draw is constantly over 300W and average FPS goes sky high instantly! On LOW preset the power draw never drops below 320W. This means the GPU is being starved.



I strongly believe there is something with the DCS 1.5 engine not being able to feed the GPU in time when running 3 screens in high FOV ("3 Monitors" profile) WALL mode.

Bottom line with high-FOV "3 Monitor preset" multi-monitor setup (BOX): It's playable at butter smooth FPSs for sure however one needs to set general quality PRESET to MEDIUM or LOW!

Bottom line with "1 Monitor preset" multi-monitor setup (WALL): Such setup performs equally good as the single-monitor setup at comparable (total) resolution. Therefore it's possible to build a cheap large, high-resolution screen out of smaller panels.

5.7 VR resolution gaming performance analysis:
The purpose of this test is to test out the impact of the running stereo "VR" 2160x1200 resolution display setup (thus simulating Oculus Rift VR headset) on the general FPS performance. The performance hit is not as obvious as on the "3 Monitor" High FOV display setup but still big enough to conclude the DCS engine is starving the cards. A 4K resolution results (HIGH preset) is added to the chart for reference.

HW setup:
- CPU: Intel Core i7 5775C @ 4GHz core / 3.3GHz uncore
- MB: ASUS ROG Maximus VII Gene
- RAM: 4x4GB DDR3-2133 C10 12-12-28 1T @ 1.35V
- GPU: GTX 960 and GTX 980 Ti
- Drive: 128GB Crucial BX100
- OS: Windows 10 Pro x64
- Cooling: EK-XLC Predator 240 - liquid cooled CPU; factory cooling on GPUs
- Monitor: Dell 2713HM
- Drivers: Nvidia 361.43


Image settings as tested (2160x1200 "Stereo" mode):


Results:


Simulated VR resolution performance analysis:
-
Ironically enough, GTX 960 (a 200€ card) here performs identically to the GTX 980 Ti (a 650€ card) which further points to an obvious bottleneck, which is most likely not hardware related. Since the GPUs are pushing a mere ~ 2.6MPix image here (compared to ~ 8.3MPix at 4K), both GPUs more than suffice for the workload.
-
In order to maintain higher FPS the same tricks apply as when running "3 Monitor" High FOV setup. Drop the preset to either MEDIUM or LOW.
- Just like before, the GPUs are starving pretty much for the majority of the time when image quality is set to HIGH preset. The only time GPUs run at peak performance is when the view is facing towards the sky or clouds (no ground objects needs to be drawn).
-
I have also tested custom HIGH preset (only Visibility set to LOW and Trees set to MINIMUM) trying to show the effect of number of polygons/objects on the FPS.
- Doesn't appear to be CPU nor GPU bound. Has to be DCS engine limitation or simply GPUs cannot cope with number of polys on the screen.

5.8 GPU architecture impact on the FPS:

Spent a ton of time trying to get 4K VSR on a R9 280/290/390 (CGN) family (since I'm testing on a 2560px monitor using NV DSR / AMD VSR for 4K emulation). The problem is these cards can only put out 4K@30Hz over HDMI 1.4.

AMD is currently not a good choice for 'cheap' TV 4K. The problem is that these R9 200/300/Fury/Nano cards can only put out 4K@30Hz over HDMI 1.4. The only way to get 4K@60Hz on current gen AMD is to use DisplayPort (DP) video outputs, which works great - 4K PC monitors with DP video inputs are readily available, however DP 4K TVs are not. If your 4K TV only supports HDMI it's better if you get NVIDIA. Alternatively you can purchase DP 1.2 to HDMI 2.0 adapter which bypasses all of the aforementioned issues. At the time of writing (Jan 2016) the cheapest 55" 4K@60Hz TVs with DP video inputs are still 8-10x more expensive than their HDMI 2.0 counterparts.

Test system:
- CPU: Intel Core i7 5775C @ 4GHz core / 3.3GHz uncore
- MB: ASUS ROG Maximus VII Gene
- RAM: 4x4GB DDR3-2133 C10 12-12-28 1T @ 1.35V
- GPU: (various)
- Drive: 128GB Crucial BX100
- OS: Windows 10 Pro x64
- Cooling: EK-XLC Predator 240 - liquid cooled CPU; factory cooling on GPUs
- Monitor: Dell 2713HM
- Drivers: Nvidia 361.43 / AMD Crimson 15.12



Final results are as following:






GPU Architecture Impact result analysis:

- Please allow for +/- 2% result accuracy. The overlapping graphs peak/dips are always a good sign of a reliable data aquisition.
- Currently all the tested GPUs are powerful enough to drive FHD resolution. At FHD resolution most of the NVIDIA GPUs seem to be CPU bound (as shown by almost identical max and min values).
- All of the tested GPUs, including the old GTX 580, are still proving to show adequate performance at WQHD (2540x1440) resolution by maintaining minimum FPS above 30. Smooth gameplay at this resolution starts with R9 280X (HD 7970). All of the tested NVIDIA GPUs are still pretty much CPU bound as the results between the GPUs are close to nill.
- Only at 4K the difference in GPU power starts to show - currently, the most powerful GTX 980 Ti and Titan X are in the league of their own while GTX 780 Ti still holds ground against the new GTX 970.
- Generally, NVIDIA cards offer higher minimum- and lower max FPS
- CrossFireX seem to cause micro-stuttering which can be remedied by setting MODEL VISIBILITY to off (however I haven't found that function in settings as of version 1.5.2)

Sorry, this is HW benchmark, we're assuming all GPUs and CPU platforms provide the same image quality.

P.S.: thread updated with CPU and DRAM frequency scaling

Happy New Year to everybody!

I have added test: 5.5. Display resolution impact on FPS to the 2nd post of this thread:
Spoiler:

The purpose of this test is to test out the impact of the display resolution on the general FPS performance. The display resolutions tested ranged from FHD to 4K, which should cover the sprectrum from the entry-level PC screens to latest 4K displays. I did a brief study with Radeon R9 Nano on my setup to see if what is to be expected when pushing GPUs to draw 8+ megapixels.

HW setup:
- CPU: Intel Core i7 5820K @ 4.0GHz core / 3.3GHz uncore
- MB: ASRock X99E-ITX/ac
- RAM: 2x8GB DDR4-3200 C16 18-18-36 1T
- GPU: AMD Radeon R9 Nano (+25% power target)
- Drive: 2x 256GB Crucial BX100 @ RAID0
- OS: Windows 10 Pro x64
- Cooling: EKWB custom loop liquid cooling (GPU, CPU)

HW setup configuration for this test:
- Same as above, just tested out on three different resolutions: 1920x1080 (FHD); 2560x1440 (WQHD); 3840x2160 (UHD a.k.a. 4K).

- Somewhat expected result for a high-end GPU, the R9 Nano (and alikes) really start to shine only at higher resolution. It is an total overkill for the FHD. This GPU (and alikes) is strong enough to drive single 4K monitor resolution with ease.


Best Regards,
Niko

Thanks Cibit. I'm trying to get this GTX 750 card here working (doesn't want to post no matter what). Hopefully I can add a Radeon R9 280X (HD 7970) and -R9 270X as well if those cards in my drawers still run like they should:



Luckily with Win8/10 changing out GPUs is even less of a time consuming task

Best Regards,
Niko
