DCS 2.7 VR performance

[Charly314159]

As feared 2.7 has brought a massive performance dump in VR especially on top of the clouds.

 

I get massive stuttering when on top of overcast weather. This is with a 2080ti, a 5600x, 32gb, and a HP reverb at 120% steam and pd 1.

 

Do you expect all vr user to have a 3090?

strange most reports I am getting are for good performance. 

 

please share your dcs log, and your settings in dcs and vr and we will try to help you again

 

thanks

I was quite surprised to see that the performance is at least as good as 2.5 in VR even with the enhanced visual effects and clouds set to ultra. 

 

Great job ED. I really love the new Digital Cloud Simulator

Great for you, what's the point of coming to the bugs section to post about it? 

 

Do you think we are lying?

Same here, stuttering even with Clouds in LOW and same settings as before.

I am running a 3090 with an AMD 5800X and its unplayable now.

 

what makes me wonder: during troubleshooting, one time I was getting back to Windows to check my settings and suddenly DCS was running well, so I even increased the settings -> then I tried out a different mission and all went back to stuttering. I could not reproduce the better performance again.

 

where can I find the dcs log to attach it?

thanks

Clouds on ultra, performs perfectly.
Maybe lower the % on the Steam settings.

[Csgo GE oh yeah]

Clouds look pretty ok but also for me massive performance impact in VR. 
Going from 18 frametime to 25 , that's pretty massive. 

But i do have that "DCS VR OPTIMIZATION" thing running and mask is not a circle anymore but a weirdly irregular shaped thing. Maybe wait for the new VR shaders that might help a bit.

Performance is ok with my set up, GPU temps not above 80 deg and FPS is good for me in VR. I haven't yet checked what FPS I'm actually getting but it looks smooth to me in VR.  Overall much better than I was expecting.

 

It also looks overall MUCH clearer than before, way better, considering I've got a Rift S and not a G2!

Again good for you... Why do you need to pollute this thread if you have no problem?

 

 

I have massive stutter on high end hardware so do other people.

Hello, a nightmare for me too when I had splendid perfs with the previous version. I take for example the mission "free flight" with the P47, map "La manche", ultra fluid in vr before. Now, Even with the clouds in low, everything gets complicated as soon as you arrive at the edge or under the clouds. It becomes strictly unplayable after a while. I will try with the Syria map.

ps: 3d clouds in VR are not pretty, without VR they are.

I've heard from a lot of people that they either have the same performance as before, or better. Me included.

Ah, if you have heard it then. We are probably just making it up...

 

[Svsmokey]

No one is claiming you are making it up , no one is claiming you are a liar , and no one is polluting this thread . 

Different systems/settings , YMMV , as always . I hope you are just frustrated , and don't have this attitude always .

I'll post my results here shortly , pro or con , and maybe it will help to resolve this problem by narrowing it down .

@BIGNEWY Similar to OP performance has decreased for me with 2.7. Performance is worse for me with this patch even when using the VR graphics preset.
I've attached my dcs.log

Yes I am highly frustrated tonight. Despite what happened with 2.5.6 with regards to performance , ED is again rolling out an update which is causing a 30% dump for some of us.

 

It's still the same piling up on an outdated engine and I am pretty sure we are again going to suffer the consequences for the better part of the year.

 

Despite regularly upgrading my pc my settings are getting lower and lower to a point where I am not sure I can enjoy it more than 2.5.5

Hello, I have made a couple of test flights and noticed a severe stuttering only when there are clouds on scene.  All was working much fluid previous from the update.

DCS is unplayable at the moment for me. In VR the clouds/sky bounces around and jitter, and it makes me nauseous, and I have never had a problem with nausea in VR. Please fix this before the Hind comes out...

 It doesn't matter if you are.  I am and I've gone from, on MP servers, 50-60 fps in a Reverb G2 pre 2.7 to 30-40 fps post 2.7 and I have made no changes to any settings. So, something is eating the performance.

[Kovacs]

I changed my  settings, it's much better,

Sorry, in French

My specs below . No overclocking Settings are :

PD 1.4

ground textures low

cockpit shadows low

civil traffic low

visibility range high

MSAAx2

All new settings default EXCEPT

Clouds high

Trees 70%

Clutter maxed

Preload maxed

Chimney smoke 1

Af 8

 

Loaded the F-18 Caucasus FF in mission editor and changed clouds to 1st overcast level .

Flew very low over Batumi , between and above cloud layers , with lots of rolling and sweeping scan fore and aft .

 

If anything , i have gained some performance .

Hope this helps .

 

Edit : Forgot to mention i deleted FXO and metashader files .

I normally only play stable but of course hoped over to the Beta for the clouds. I made all my settings the same as stable and FPS performance was notably worse for me. To clarify I am perfectly happy with performance and settings in stable (took me a while but its very dialled in) but in the Beta the FPS was below what I would be happy to play at with my same settings. Overall probably about a 20FPS average loss, although with ASW off and FPS fluctuating it is somewhat hard to guage. I did run the same mission I created in both stable and Beta 2.7 but I was trying lots of differnt clouds settings.

 

I did also note a lot of issues with the new clouds, what looks like heat haze and shimmer, some clouds renered very stangly that they just looked odd and out of place. Everything just looked a bit out of focus and it started to cause me eye strain.  

 

For now I am happy to hop back to the stable game. I am sure ED will optimise further, that is the point of Beta.

Most of the stutters I experience are when I have a dense city in my FoV. Then it clears up when I'm past the city. Which setting(s) have the greatest effect on city rendering?
