i7 worth it for DCS?


Recommended Posts

As my current rig won't cut it for DCS at the moment i am looking into a future build.

My i5-4690 has served me well in the past and i was always told that an i7 wont be neccesary for gaming for a few fps gains.

 

So looking at coffee lakes. 8600k vs 8700k will the i7 see a noticable improvement in DCS over the i5?.

Running at 1080 an 60fps/Hz?

Will be running no OC.

 

Thanks.

DCS may perform slightly better because the 8700K runs at higher Hz ( if you OC, the difference will not be noticeable )

 

but the extra cores that the 8700K brings will be useless for DCS

 

so if you don t plan to use heavy multi core apps, and want to save a few hundred $, stay with the 8600K.

Just something to think about with regards to DCS and multicores...

 

A) Vulkan...

 

B) Other programs running at the same time, including the OS will be using those cores, taking load off the one core running DCS, so in effect helping it run better.

 

edit: Just get the 8700K and be done with it. Mine is overclocked to 5.0ghz.

Thanks for the answers. Well i guess from a future proofing standpoint the i7 route is worth the extra cost. And fingers crossed when the 11xx series gpu's comes out, prices of 1080's will come down to at least what they cost new 2 years ago ;)

If you have "ZERO" plans to overclock, save a few bucks with the 8700.

For what it's worth... one of the reasons I'm planning a Ryzen5 build vs Ryzen7 is because I'm not convinced that any current flightsim needs more than 6 physical cores and I also do not know of any flightsim that uses logical cores.

 

Also I feel that Intel is taking the p### making consumers delid their CPU to get full thermal performance.

When I fly DCS, my 6c/12t 8700k is taxed up to 60+% many many times during online gaming.

 

Yes, there are times when it sits at 14% CPU Load, which is still more than 1 core, regardless, most of the time it flips up & down between 20-25% and 50-60%.

 

This is with NOTHING extra enabled, no YT streaming, no VR, no TiR, PLAIN SLEEK DCS.

 

The next one who says DCS only needs 2 cores will be shot :)

Ask Pilotasso, he runs a 2700x, he uses SEVEN of his 8 cores in DCS.

 

When Pilotasso says it, it is like he says.

The bottom line, which is often ignored, is that when DCS is running it is not the only thing that Windows is doing. Even if DCS only used two threads, the background applications and Windows itself will take advantage of the rest.

Cichlidfan is right even though DCS is only a 2 threaded application you might be running other things in the background which a i7 would help. Saving up the extra cash for the i7 would not only help now with DCS and background task but also down the road with other games you might play.

 

When I purchased and build my first Pc I had a i5 2500K when I upgraded down the road to a i7 I never turned back....Right now im running a i7 8700K and GTX1080

You really think the "others things in the background" use more than a heavy game like DCS? As told many time ago, Hyper-threading tech is not use by DCS an many of the games and applications. Physical core is a way better.

True. However, most people have lots of stuff running in the background and every little bit helps in that instance.

 

Unless money is very tight, in which case a different hobby is recommended, then go for the i7. It might not be a requirement but I am a firm believer, since I can afford it, that more power across the board is better.

I use 6 of my 6 cores, Pilotasso uses 7 of his 8 cores from his 2700x.

 

Those days, with 2 cores, are OVER

Right now, chances are you won’t fully use a new i7.

For that matter, my ancient i5 2500 is usually sat under 60% usage of each of its 4 cores as my 1080 is the bottleneck in VR.

However, Vulkan is expected to offload some of the grunt work to multi-core CPUs and for that, I’d expect a good i7 to do wonders.

 

I’m current holding off replacing my base unit until we get a better understanding of the implications in DCS.

baseline: if overclocked, a 2700 will be a nose ahead even from the 2700x, fantastic outcome :)

 

This is a nice solution if you think "OC" and tinker yourself. Might be my very next CPU, or 2700x..or new board..I HATE MY BOARD !

You should still check if your GPU is getting feed enough to be maxed out and stable in sim? I was helping a guy recently as he was having stutter problems running a GTX 1080TI....:huh:

This was my usage on 4 main cores below, sim on max settings no GPU overclock.

I was using the 4 main cores, so it's more like I was using 50% of all 4 cores with one spiking all the way to 90.

ProcessLasso locked & engaged, looks like it.

 

Mine often goes to +60% load for a few seconds, then 40-50%, mostly 20-25%, lowest is like 14% but that is rather rare.

 

With a ZickZack curve like shown above, flying is no fun. Nice find David

i7 and dcs

 

Hi...before you buy the i7 try your motherboard maximum memory capability i have on my motherboard 32 Gb....dont forget DCS runs on top of Windows that takes lot of memory if it has lot of installed programs....

Well CPU utilization has varied between 13% and 43% when I tested my 2700X over Nellis map and that varied with the number of objects on screen (13% was above the desert while 43% was over the urbanized areas). ED has stated that DCS 2.5 already incorporates some elements of Vulcan API, so I lean towards the conclusion that higher the detail you set on graphics configuration, the more spread the detail will be across multiple cores.

 

I would like to know the detail that this 2600K was configured to ingame, and the screenshot appears to indicate a rural area was used. I suspect at the time it was taken without a whole lot of objects visible. Both the CPU and GPU are lightly used and that doesn't look right for proper testing purposes. If you fly over Dubai or Nellis your going to see CPU bottlenecks for sure (hell even some cities in the Caucasus map will do that). I just dont think that 2600K can feed a 1080Ti because during my testing the GPU was locked at 100% even when the CPU usage dropped towards lower % (make sure VSYNC is off for testing purposes or else you cant compare FPS on different machines).

 

 

If you are building a machine, you have 2 possible approaches to max your performance in DCS on the CPU side:

 

1- either you have an Intel 6 core clocked really high

2- or you go 8 core for more threads on AMD side of things (Skylake-X 8 cores performs on same level for gaming but costs a whole lot more)

 

right now option 1 has an advantage in FPS numbers but that seems to be shifting away to 2 gradually. Not that you will notice a difference right now in your gaming experience, or heck even the price for the builds are similar.

that’s because the same “job” is being context’d switched over to the next free random core. but none of the cores are being fully utilized.

 

most likely, someone could turn off 2 of those cores, leaving you with 4 and you wouldn’t even notice the difference.

Lots of good input here. I pretty much decided on a 8700k. My 1060 6gb will carry over to the new system until a 1080 is not crazy expensive anymore.

Last time i fired up DCS was right after 2.5 beta came out in january, and my fps on ground was 25-35 fps slowly climbing to 60 at altitude :( single player 1 aircraft loaded in caucasus.

Hopefully some improvements have been made in a couple of months.

The DCS itch is real now!

I have two builds im on the fence about, and the only thing holding me back from pulling the trigger is intel still not announcing the z390 boards. It's clear that the board will support CL, but will it support the 8700k? The z390 is supposed to have better usb3.1 support. Its frustrating. I'm tempted to pull the trigger on the 2700x build just out of spite because Intel is pissing me off.
