Computer: Windows 10 Home 64bits 1709 (16299.192) I7 3770K OC 4,4Ghz GPU Nvidia GTX 1080 drivers 388.71 16GB Ram C:>SSD 128 for Windows and D:>HDD 1TB for all others stuffs Display using monitor 1920x1200 or Oculus Rift Hi Guys, long time no see. Last time I launched Rf2 was on summer 2016... Life let me currently get back to Sim, so yeah, I'm back! Today, as I saw VR and DX11 landed for the best Sim I decided to have a go. The game is set to not use any Beta version in Steam (may I have to choose one?). Verified files integrity did not fix anything. Flat screen worked fine, no noticeable problem, it's really nice (DX11 I guess, great job!). Trying VR, I launched first Oculus Home (Dash Core 2.0), and then Steam, and then rF2 from Steam. Was able to change Video Setting using the launcher to try "Headset" (and also "Headset+mirror", same result). The "Unable to init VR runtime: Installation Not Found (100)" message box appear after clicking "Single Player", and clicking Cancel or Retry do the same things : nothing. Game still running, so killing it from task manager or rebooting is needed. As it sound as a path problem : Oculus stuffs are on my D:\Oculus and Steam are on D:\Games\Steam. I also reinstalled classic runtimes (2012/2013 x86 & 64) just in case. Other Oculus apps/games/Sim work fine. Integrity of game files verified, and as a reminder the 2D monitor version work like a charm, so it's a VR thing as error said... Does somebody met the same issue? What I missed here (launch order perhaps, etc.?). Thanks for your helps! I can't wait to run it in VR YoLolo Edit : I found this : https://www.studio-397.com/2017/05/open-beta-with-directx-11-and-virtual-reality-support/ Does it still valid informations (May 2017)? That mean I need to install SteamVR too (Oh no, I have bad story with it and fps on my machine)?
