Just played Lone Echo with Link and it worked well. Also played Quake 2 and Half-Life, using Sidequest to install and copying the full games from Steam - also work very well (but need to have good VR legs).
Elite: Dangerous - did several hours with Link - same with P3Dv4 and DCS World. All worked well with zero negative effects. SDE is obvious, but that's pretty much a given - not as bad as CV1 though.
