how does it run in VorpX? i was disappointed with most of the games i tested with VorpX (surprisingly, the best game performance i found was Grim Dawn, which wouldn't be the first game i would think of playing in VR, but actually plays really sweet).
i tried running Valheim with this: https://www.notion.so/How-To-Force-Any-Unity-Game-to-Run-In-Native-VR-Mode-cf8c50f66f2740d5b692db786a8386a1
It launches into VR mode, but as this method claims, the UI doesn't show in the headset. Main menu looks fine (you can see your character standing in the woods and look around), you can peek under the headset at the monitor to start the game, but when the game loads the VR camera is like, miles away from the player hovering in a random spot.
there is this camera reparent mod: https://github.com/Raicuparta/unity-vr-camera-reparent
however, even though melonloader says it installs correctly, launching Valheim doesn't launch melonloader and I can't seem to figure out why.
So basically: you can force native Unity VR mode with this mod, but the camera's broken (same thing with SkaterXL, game launches but then the camera is 100 feet over the player's head, otherwise everything else works, controls, etc.)

Just my two cents. I have to pull the vorpx installer off my old computer (cause i never really used it) but lately i'm more curious about trying to run Unity games using this native "force VR" tweak. If anyone wants to take a stab at it and see if they can get melonloader to launch properly, the camera mods might fix it (otherwise if anyone knows how to tweak the camera settings using UABE (https://github.com/DerPopo/UABE/releases/tag/2.2stabled) let me know so i can take a stab at it.)
