Forcing DirectX 11 in Steam VR has helped my VR performance and clarity tremendously in both DCS and IL-2.  Instantly got about 15-20 FPS increase and was able to turn off motion reprojection and also increase the resolution.  Using Reverb G2 with 2080TI.  I'm now getting consistently about 50-60 FPS, no stutters.  In IL2 I have MSAA at 4 with everything else pretty much maxed out.  Still playing around with DCS but this definitely increased performance dramatically there too. 

It is a setting in the VR Dashboard, not in the Windows Desktop Steam VR settings.  Have to get to it using your VR controllers.  For me pressing up or down on controller thumbstick while steamvr is running (game not running) brings it up.  Setting is in the little "settings" gear icon.

I tried :

- turning on headset

- start steamvr

-start controllers (which appeared in the steam vr environment)

Tried all possible movements of both controller sticks and all buttons, but I could not get any response other than the normal vr menu which does have a gear, but it just takes you to windows settings.

Did I miss anything?

Sorry Jaus, my bad it's actually not the gear, it's the smiley mask guy icon on the far left "Windows mixed reality for steamvr"

 

From there it's "Graphics"... "force directx11"

Alternate method: "[your drive]:\Program Files (x86)\Steam\steamapps\common\MixedRealityVRDriver\bin\win64\OpenVRSettingsUX.exe"

for those of us who still have the controllers in the box. 😆

Hmmm, I'm not seeing either of these options.  

What is the starting point from which you access the "VR Dashboard" ?   Is that a separate software?

I also don't see the \MixedRealityVRDriver\ folder in the path Snaggle quotes.

What do you see can you post a screen shot?

 

I'll post a screenshot of my /steamapps/common folder when I get a chance.   

Labroisse, are you talking about a dashboard  you see on the monitor or in the headset?

It´s this path on my installation: 

 "C:\Program Files (x86)\Steam\steamapps\common\MixedRealityVRDriver\bin\win64\OpenVRSettingsUX.exe"

Oh, Snaggle yet posted the path above ☺️

This is what I have:

C:\Program Files (x86)\Steam\SteamApps\common\MixedRealityVRDriver\bin\win64\en-GB\OpenVRSettingsUX.resources.dll

no OpenVRSettingsUX.exe ??

Here is my  C:\Program Files (x86)\Steam\SteamApps\common\ folder.

I've also searched it for instances of "openvr" and only turned up some "openvr_api.dll"s scattered around

I finally figured out the dashboard.   I had turned it off when I started using VR because I couldn't figure out how to close it once it was on screen, then completely forgot about it.

I've re-enabled it and found that I can let it start with SteamVR and close it by pointing a controller off of the dashboard and pulling the trigger.

Forcing DX11 didn't make a difference for me in my acid test (FC - "Airfield Defense" mission, 15+ AC and buildings nearby).   50-60 fps at the start of the mission is what I had been getting.   I'll keep observing in FPSVR.

Never have found that .exe.....

@Jaus check your steam library and see if you have a program called "windows Mixed Reality for SteamVr [beta] installed. I suspect that is the reason you don't see the ..\MixedRealityVRDriver\bin\win64\OpenVRSettingsUX.exe in your folder list.

@Jaus I guess you got a Valve Index headset or a Vive, therefore there is no need for MixedReality for Windows installation folder, where we HP Reverb user got this .exe located?

 

I have a reverb G2. 

I do see a WMR for SteamVR (beta) in my library.   Is that bad?

In the headset only.

NVM, saw you got it.  Sorry it didn't help.

Not at all, just thought that might be missing hence no folder:

If you got the menu to change "force dirext11" in SteamVR/WMR for SteamVR , the .exe to run this program must be somewhere. As you already could have opened the menu in VR, it´s just about solving this mystery of the missing .exe 😄  So next guess is, that you might have redirected the games and apps downloaded through Steam to be installed on another partition of your system? 
I got this .exe linked to the desktop, so it is easily to open, without using VR in the headset ( meanhwile I don´t use Steam, SteamVR and WindowsMixedReality for SteamVR at all anymore ). There´s nothing wrong to do things one way or the other.

Maybe, if you got "Windows Mixed Reality for SteamVR" listed in the library, there is a way to see more information about this entry in the list to get the path to the folder where it is installed?

Right click on "Windows Mixed Reality for SteamVR" -> properties -> local files

I found it. Had to scroll to the bottom here: C:\Program Files (x86)\Steam\SteamApps\common\MixedRealityVRDriver\bin\win64\  below all of the folders. 

I opened the .exe and it brings up settings. "Force DX11 Mode" was off. I enabled it, restarted SteamVR and it's now enabled. That should be all I need to do.. right?

Affirmative 😄

@Vonrd some places say the Motion Vector locks FPS at 45, mine was on disabled, going to try auto tonight.. just a thought.

That was it.   I had completely forgotten I had installed some steam apps in a different hard drive.   Thanks, I see the .exe now.

I tested and got a solid 45FPS with disabled re-projection on DirectX 11 but get the same with DirectX 12, I have all setting really turned up.
