[REPORTED]2.5.6 Performance

[Gripen 4-1]

ED / Bignewy please take a look on the post from lukasz7 here: https://forums.eagle.ru/showthread.php?p=4326414#post4326414

 

The edited lua file improved performance in some parts oft the OB 2.5.6 massively!!!! But same low FPS in instant missions with a lot of AI 25-30 FPS in VR with HP Reverb.

So maybe the SA is part of the solution but not the whole Problem!

apologies I though i was missing an essential fix that would get rid of the stutters

 

Initially I had the game installed in a hdd but the sutters were apparently there and I decided to move it to an SSD

 

while the stutters have decreased significantly since then there are still some really minor pauses that break the real time flow of the game

 

my specs: 7700k 5ghz oc , 64gb ram, 2080ti windows 10 , no AV and disabled all native virus protection

 

Try preload to max .

We are testing fixes currently.

 

thanks :thumbup:

That is great to hear, but in my opinion you guys released 2.5.6 way too early without enough proper internal testing , even for a beta.

Noticed a significant fps drop in multiplayer on my regular server (30fps ground to 45 air). It's probably AI related. Quick Missions with no AI run as normal (60 ground to 100fps in air).

 

EDIT disabling TacView doubled my frame rate. I'm now getting 70 on the ground and hitting over 100 in the air. DCS is playable again!

It is interesting that I get nearly the same frames in VR with 4x mssa and 2x msaa. Seems that 4x msaa requires less performance than before. But it looks way better. Perhaps the new VR mask helps to make 4x mssa usable in VR. With both I get low 30s in the coldstart mission. But only when I look to the tower. When I look in the cockpit I get my 45 FPS most of the time with my reverb. ED it seems you move in the right direction!

Looks like you are right...I got from 8 FPS to 20 FPS on a mission with 400 moving ground units after i disabled TACVIEW !!

Ok tested a F16 freeflight an 4xmsaa is still Eating up FPS. Seems that something else is FPS costly on the supercarrier

[Charlie-1]

Hello Im on the beta and from time to time I get little pauses and it is starting to make my head hurt if playing for a medium to long time

 

Is there any way to get rid of these micro pauses?

 

I had this and cured it by disabling track recording.

 

You can see the thread/ history here incase it's the same casuse for you.

The last OB patch solvent the performance loss with Tacview

Hello everyone, hello BIGNEWY!

 

I really hope you are working on those fixes for FPS drop cause it is still there big time. Started playing beta for the Supercarrier and immediately noticed a significant drop in FPS by more than 50% on the same settings as on stable version. For me, I don't think it has got to do anything with the Supercarrier cause I get the FPS drop on every map with no carrier.

 

Any news maybe? Is there any info that we can provide to help? :blink:

[Motomouse]

You can not have the same settings in OpenBeta ans Stable right now. Perhaps you like to start exploring there.

[MrDeadpool]

@Motomouse

 

Thank you. Would you care to explain why so I can understand what to do?

[speed-of-heat]

taxes the GPU and CPU a lot more than 2.5.5

[MrDeadpool]

Basically, what you're telling me is that if someone doesn't have a PC like the one you have in your signature space, you have 10 FPS and that is it from now on? :D

i don't know that to be true; and i dont know either what your specs or settings are ... so its difficult to provide objective guidance... but i take a hit of about 15 FPS (from 45 down to 30) if i have shadows switched on on the super carrier ... so that's a major frame rate killer at the moment..

[Motomouse]

You can not have the same settings because the OpenBeta has additional settings and features.

[MrDeadpool]

Thank you for your answers. I just said I didn't touch any settings when switching to beta and got 40-50% lower FPS. In my humble opinion, that is not a reasonable update if it is that heavy on your computer. I might be wrong...

nice optimization in Persian Gulf for 50USD

what?

[dr_anthony]

+1. Had 10 FPS with last update. GTX1070. (((((

This is exactly the same what is happening on my computer as well.

Found no other solution than disabling shadows completely, no matter what I do.

yep same...

Stutters galore

 

Well... I've discovered the frame rate in 2.5.6 is very similar to what it was with 2.5.5, but now I get constant micro-stutters every second or two, with massive long stuttering at random every 10 seconds or so. Worse closer to the ground. This did not happen with 2.5.5. It was silky smooth with the same settings (attached settings grab).

 

My frame rate is locked with an autoexec file at 30 fps, and even above Las Vegas I get 30 fps in the Hornet, and medium-high settings (see screenshot). So I know the hardware power is still ample.

 

Granted, my computer is older, but I will have to make do with it for now. It's an MSI laptop - GT70 running windows 8.1, with an i7-4810MQ @2.8GHz, 20 GB ram, Nvidia GTX 870M card (3gb dedicated), and the drive DCS is on is a Samsung EVO 860 1TB SSD with more than 25% free space (separate drive from OS, which is also an SSD). I tried updating my Nvidia firmware, but driver 425.31 is the last/newest driver for my card.

 

I identified any MSAA setting other than OFF introduces even more and aggressive stuttering. SSAA and SSLR introduce a very low frame rate. So I'm enforcing anti-aliasing with Nvidia Control Panel, set to FXAA On, Override, 8x. Looks pretty good in-game, and almost no performance hit, but screenshots have no anti-aliasing (bummer...).

 

Also set Nvidia power management mode to "Prefer max performance" and set Max. pre-rendered frames to "1" - this seems like a sweet spot. Helps a little...not much.

 

I feel like I've tried everything...

 

-Disable Hot-plug devices.

-Turn off shadows and various tweaks (like that graciously made available by Mustang) to disable ground shadows.

-Disable autoexec file/frame rate limiter.

-Ensured via task manager that all cores are set up to be utilized.

-Deleted the MetaShaders2 and fxo directories

-Turned off Nvidia control panel overrides for anti-aliasing, etc.

-Steam Verify Cache

 

None of these things helped.

 

Out of curiosity, I set my display settings to the LOW preset, and still had the stutter. So that indicates something other than graphics settings.

 

When I'm flying, my CPU usage is around 30-50%, and my GPU is 100%.

 

I wish I could roll back to 2.5.5 but I dont think Steam allows that. I'm baffled why 2.5.5 was smooth (and most previous versions of DCS, for that matter) but 2.5.6 is so herky jerky. Of course this happens days after I buy a bunch of modules in the 50% off sale....

 

Thanks for any help/ideas!

[Shuenix]

No serous improvement ? So, I don't need to install an take my Hotas out of the cupboard yet ?
