Haven't tried it myself yet because I'm unable to play Skyrim VR until my leg is fully healed but this is pretty huge if it means that we won't have performance issues playing VR games in our Steam libraries. 😮

Ok, so I made tests yesterday with IL-2. It work with an issues which could come from me : FPS is lower is I use the SS option "supersampleRatio" inside the configuration file opencomposite.ini, versus the debug tool/ OTT supersampling.

In my test scene and having OTT set with my usual 1,5 SS I have 89/90fps. Without OTT and using supersampleRatio=2,3 (which should be the equivalent in SteamVR, please corect me if I'm wrong) and OpenOVR DLL I got 60fps.

I could have wrong here (OTT 1,5 = SteamVR 230%) but visually it match, and I used datas from another thread showing those ratios.


On side note, using OpenOVR DLL make loading time really shorter!
Edit : I'm adding, using OTT at 1.5SS and OpenOVR DLL and I'm back at the same FPS and visual quality than using SteamVR so it's pretty sure a problem with SS set in the opencomposite.ini file.

Wait, so now it has some settings? So cool! Man I love @znixian, that's a hardworker for sure!
EDIT : Just tried that on VRChat, it works like a charm! I changed the SS values to have no lags, it seems alright for me (SS 0.5 did seem like Steam VR SS 50%).
Also, I just tried Skyrim again, the fact that it shows hands instead of controllers is priceless. Thank you so much! It breaks so much immersion to see the high-tech controllers in that fantasy middle-age world, so I'm glad to have hands instead!

out of curiosity, with this enabled, if i play a game will it still show me as playing said game on Steam? it would probably mean that I cant chat with my steam friends while in game anymore huh?

Probably not, indeed. That said, there are many other options to chat with them. Many games have built-in "friends system", so I guess you could just add your Steam friends in the games ^^.
