poor VR performance after latest update(s?)

[Helios1138]

I'm getting 100% GPU load on the menu / in mission editor screen and 95-100% in-game. Settings did not change. Tried removing fxo/metashaders. In-game tested on empty Caucasus map with F-16 at midday.

 

2080ti / Rift S

i too have had horrible fps after this up date went from a stable 45fps to stutters and freezes my specs are an i9 9900k 32 gig ram and an rtx 2080ti and my HMD is the hp reverb

I have your same equipment, I include the hp reverb, except for 64gb of ram and my performance is similar to the previous patch. Check that the data capture of TACVIEW is disabled is giving problems of loss of fps if it is not updated. Also removes metashaders 2 and FXo from the folder of saved games

Ya I noticed a lot more FPS drops and stutters and it was not that way before. I get major stutters every few minutes or when making hard turns in the hornet or F14. The FPS will drop to zero fast then respond> I have the CPU fixed at 5ghz with no hyperthreading and my gpu is overclocked. i have tried turning graphics settings down to low, with no shadows it still does it. Single player or multiplayer it doesn't matter.

Ok I am glad I am not the only one - I have similar to everyone else (i9 9900k@ 5ghz, 64 gigs ram, RTX 2080Ti and the reverb).

 

 

for whatever reason my FPS Range is stuck between 20-40... and I haven't done a thing other than update drivers and the program. Before I was 40-45, but now im 30ish-35. Everything to lowest - max of 40-45 again... its really frustrating me, but I am glad I am not alone!

[Helios1138]

just to make sure I downgraded to stable (which AFAIK is the latest 2.5.6 before the last update) and under the same conditions, I'm getting ~60% GPU load and solid 45 fps. So this issue is definitely from the last update

Isn't that normal?

 

 

Since I'm in VR, as soon as the simulator is started the GPU is set to 96% in the initial menu and 94% in the Editor...which is not if it's not 100% is quite close.

 

 

This is with the glasses still on the desk and the fps around 230. Once I put them on, the fps goes down to 80 and the GPU consumption at 45% is noticeable as the graphics card fans relax.

 

 

Which I've never understood.

 

 

These fps (on the main menu) are usually used as a reference to compare the update. At the time of 2.5.5 it reached 300. Always talking about how I use the shadders mod, of course

Tried the latest open beta version. Unfortunately, the issue is still present - VR performance is still much worse than stable.

Can you post your

 

nvidia settings

DCS settings

steamVR settings / oculus settings

system spec

and what version of windows you are on.

 

thanks

[hazzer]

I have noticed that fps jumps up ~10 fps when the window isn't selected.

[Hoirtel]

Odd, after the patch on the 15th I noticed a massive FPS boost in VR, running a similar machine to others, on rift s. All SP, previously 30-40 FPS on the ground, now 40-50 which is now over re projection speed so much smoother. Same increase away from the field, about 50-60 with almost getting to 80 in high altitudes. I've got very high settings apart from shadows on low + flat. My GPU is also mostly at 100%, which is what I want. Making full use of it, ready to upgrade....

I'm not using SteamVR, and I'm not sure what settings are there on Oculus, I didn't modify anything there. Is this it?

 

 

I'm launching the game like this

Try delete metashader2 and fxo folder, after that your problem solved cheers!

other experts will have to chime in, but what I can remember, some of my settings are:

 

 

water - medium

civ traffic - none

clutter / grass - 0

pre-load radius - I think mine is 50% of what you have

trees - same as the pre-load radius...

 

chimney density - 0 (or whatever the lowest setting is, 1?)

 

 

 

Next time I'm by my computer, I'll look to take screen shot...

In VR, DCS is running better than ever on my system at very high settings. From what i see in your settings, a PD value of 1.5 is quite high (DCS internal SS is very costly!) - it's better to use external SS settings and leave PD on 1.0. Use Oculus settings to raise SS for DCS, this shifts the SS workload over to your 2080ti which is hungry for work while running DCS's CPU bound tasks.

The most actual driver optimization comes from this guide:

Make sure your CPU runs DCS at high clock speeds 4.6+ GHz without any energy saving options. Don't use VR shader mod, ignore older optimization guides - DCS constantly changes, we have to keep up with it.

Things to try.

 

Test with a lower pixel density 1.0 see if you notice a frame increase.

 

try with shadows off, shadows and terrain object shadows, or just terrain object shadows. Note if there is any difference.

 

try disabling bloom effect - any change?

 

Let us know how you get on.

 

thank you

Nvidia pre rendered frames, should be as low as you can. 1 is recommended otherwise you get input lag. Might cause a stutter if your card is rendering frames too early. This helps to improve smoothness in lower end systems, but comes at a cost. My settings are very similar to yours. I also use external SS but at 1.5 on a 1080ti. It can handle that. Terrain shadows to flat is one that I have lower. I also have MSAA x2.

Hello,

 

Using external SS setting is an interesting way i would like to test as suggested.

 

What are the different way to use external SS ?

( PD stay to 1.0 in DCS )

 

I didn't find a full response about external SS by searching in the forum...

 

- using occulus tray tool ?

- using steam VR ( is it possible with the non steam dcs version ? )

- with CLI debug occulus tool ? ( used to switch to asw:30 with command line sometime )

- VRSS of nvidia driver on RTX card ?

- other

 

Thanks

[RealDCSpilot]

I have a Valve Index and i use Steam VR for custom SS for DCS. I pushed it up to 2880x3200 pixels per eye at around 90% GPU usage. I don't know enough about oculus, i think you have to use the tray tool.

Disable MSAA, SSLR, SSAA and motion blur. Set terrain shadows to flat and eyeball how your fps change.

Yes

 

1 using occulus tray tool ?

2 using steam VR ( is it possible with the non steam dcs version ? )

3 with CLI debug occulus tool ? ( used to switch to asw:30 with command line sometime )

4 VRSS of nvidia driver on RTX card ?

1: one option (you can set different profiles for each install you might have)

2: another option, possible on the non steam version

Just not both together i guess.

3: don't think so

4: can't tell, i don't have an RTX card.

Back in March, I could get 90fps stable on low doing 1v1 dogfights. Using the same settings, I can now only rarely reach 90fps. It's usually at 45fps now. It has been constantly dropping fps after every update.

For rift S and non steam DCS use oculus tray tool. It is possible to force this in oculus settings somehow, but the tray tool does this for you and allows profiles. I find that DCS will not allow changes to the tray tool while it is running. Get it running befoire DCS load, if you want to change SS settings you need to exit DCS and reload.

[fab.13]

Thanks for all the response.

 

I'll give a try with occulus tray tool ( i forgot to say i own a Rift ... )

 

If i can understand,

i cannot test using SteamVR SS with my configuration : DCS Eagle Dynamics version and Rift

You can, you have to add DCS as a game to steam as its a non steam version. This is how you would run a WMR headset. Bit pointless for oculus as DCS supports it.

[fab.13]

Great !

 

I 'll try SS through SteamVR too with this tips.

 

( i'm not aware about Steam ;-) )
