I have Subnautica on Epic and added it as a non-Steam game in Steam. The game runs fine on my computer without the headset, but when I try to launch it in VR with my HTC Vive Focus Vision, it crashes without launching. I’ve tried launching with SteamVR and even used the command ‘-vrmode none’, which seemed counterproductive but I gave it a shot anyway. Here are some resources: what I see on my VR when trying to launch Subnautica [Streamable Link] and what happened on my PC during the same occasion [Streamable Link]. I also have my logs available [Pastebin Link]. Any help would be appreciated.
Have you checked your graphics drivers? Sometimes outdated drivers can cause issues with VR games.
I had a similar issue before. Restarting SteamVR before launching the game helped me a lot.
You might want to check the in-game VR settings. Sometimes there are options that need to be enabled specifically for VR.
Could it be a compatibility issue with the HTC Vive Focus Vision? Have you tried using a different headset?
Make sure to check the SteamVR settings to confirm that your headset is recognized. Sometimes a simple reset can help.
