Resident Evil 4, Saints & Sinners, Serious Sam, and if you can stand Reddit humor Borderlands 2 and Vertigo Remastered are worth a shot. With an even higher tolerance there's always Gal Gun 2 VR. All in order from best to worst. 

Also, there are the mods for Return to Castle Wolfenstein, Doom 3, and Half Life 1+Blue Shift and Opposing Force on Sidequest. That and the Half Life 2 VR gmod mod has gotten better with proper reloading. Mechwarrior 5 and Alien Isolation are also good mods, but they don't have motion controller support. Mechwarrior 5 is best played with HOTAS anyways.

I wouldn't recommend Arizona Sunshine and Zero Caliber for PC as they kind of suck. Zero Caliber: Reloaded is fine though with the last update helping a lot.

Look out for San Andreas VR (It will be in first person) and Hitman 3 VR which are coming "soon".
