Does Half-Life Alyx work on WMR headsets? I'm pretty sure if you have controllers that are somewhat standard (i.e. are similar to Oculus controllers) you should be good to play that game. And Alyx is, without a doubt, the best VR game out there.
As far as other VR games I really enjoyed:
- The Room VR
- Vertigo Remastered
- Beat Saber
- Pistol Whip
- The Talos Principle VR (never finished this as I beat the game in pancake mode years ago, but I loved what I played of it in VR and I think it's an equally good way to enjoy this amazing game)
- Accounting+
- Trover Saves the Universe
- Moss (its sequel is also coming to Steam soon)
- Tetris Effect Connected (also incredible if you have a beautiful TV/monitor - works just as well in VR and pancake mode)
RTX 3060 should be able to cope with all of those. Alyx is probably the game you will struggle with the most, but I believe it has pretty scalable settings.
Not sure how many of those work on WMR, so you may want to check each game's compatibility out, but those are my recommendations.
But I'm not as well-versed in VR as others. I enjoy a lot of VR games, but I'm not as immersed. I pop out my VR headset maybe once every 2 months or so to play something and then put it away again, and I don't always play on PC (I have a Quest 2) so there are likely other VR games that are also incredible experiences that will work fine on WMR.
