These aren’t all FPS games, but are excellent picks:
The Vanishing of Ethan Carter is AWESOME in VR if you’re into mystery adventures
Elite Dangerous if you like space exploration games
The Elder Scrolls Series – primarily Skyrim.
Fallout 4
The Batman Arkham Series
Metro 2033
Call of Duty Black Ops 1-3, Battlefield 3-4 and even Hardline, Any Splinter Cell or Crysis game
Alien Isolation
Quake I-III
Half Life 2
Portal
The Witcher 1 and 2 if you like extended campaign games that will suck all your time, not sure if Witcher III is manageable at acceptable graphics levels
Bioshock: Infinite
Borderlands
GTA IV and V
and to tickle your fear of heights check out Mirror’s Edge
Essentially if your computer can run it, and it’s built on a major game engine like Unreal, Unity, and quite a few others – it’ll play in VorpX. The less popular it is the more tweaking you’ll have to do though because it won’t have been done already by someone else. Once you get used to the Vorpx in game menu you’ll be able to get games to run. Whether you get a true stereoscopic experience depends on how the game was coded though.
I’m sure that’s clear as mud now.. lol. But hopefully there are a couple of games on there you can check out that are well established as compatible.
