Simply rename the original "openvr_api.dll" in bin\game to "orig_openvr_api.dll", put the known working (from someone running it without issue) OpenXR version of "openvr_api.dll" into \bin\game, and run Il-2 normally. It will be in OpenXR every time. Want to run in SteamVR, simply swap them back. I even downloaded the 64 bit DLL directly from GitHub once and it was 1K in size, and that is what the switcher was "updating" to! Or am I missing something? Yeah never bothered with switcher from the beginning I have done what you say and I never bothered again...

When you use the OpenComposite Launcher you get the latest version of the dll, which may or not be broken. I see the link to the older working one is now broken, so edited my original post and removed it. Attached it to this message for anyone that may still need it. 64-bit. openvr_api.zip 601.82 kB · 25 downloads Hi do you have the working Win32/openvr_api.dll part too? It seems I need that too yes?

macro1 Posted February 27 Posted February 27 ah ok , so when the instructions further back say rename the win32 to blah blah blah that's not needed if you run the 64bit? I have the vrclient.dll in my runtime but ill try take it out and use your replacement x64 and re name that one and see what i get. Am I right in just opening the runtime and deleting and dding into that folder?

Patricks Posted June 9 Posted June 9 (edited) This is the 64 bit file i'm using for my Varjo HMD in openXR, works perfectly for me - https://www.dropbox.com/scl/fi/jb6kdfby5g1l57nvl7j70/openvr_api.dll?rlkey=0rpjxj0dbwxbu4v5l6scqw7kx&st=1b6akwhg&dl=0 Again, go to x:\IL-2 Sturmovik Great Battles\bin\game folder, rename the original something like "orig-openvr_api.dll, then place the OpenXR 64 bit dll file (openvr_api.dll) in its place. Done. Edited June 9 by Patricks
Anarcho Posted June 10 Posted June 10 Thank you everyone, I spent the night fidling with the DLLs above, Virtual Desktop, and it did work, but tunning VD + OpenXR I lost around 20fps. With Steam Link on Quest 3, I can get 90fps cap 😕 I re-Installed everytjong and SteamLinknis working again, and so far, no crashes, so I will keepnit this way untill something breaks again...
Internethetzer Posted August 29 Posted August 29 Ive tried everything out so far & wasted way too many hours who couldve been used for more important things like touching grass OpenComposite simply refuses to work as intended & IL2 always launches in 2D (except when I use SteamVR obviously) Sick & tired of this buls**t Guess I'll stick with dogshit performance

I could not get opencomposite to work at all, whatever I tried for most of the day. Only when I did a complete DDU and reinstall of the graphics driver did opencomposite work.

Reality is you may or may not see a performance increase..

I will leave that option open when Im in the mood for a more escalated solution Btw I have a AMD GPU not Nvidia, does that make any signifcant difference? Edited August 30 by Internethetzer
