I tried plenty of games over my 8 months of ownership with the Rift CV1 and while I enjoyed the experience of VR, the one thing that always stood out was poor resolution and atrocious IQ.
God Rays
Resolution
SDE
Scuba goggle FOV
Among others
Sitting in a cockpit of a plane, totally unable to read the dials without leaning (and even that was touch and go) in was unbearable to me. Even using supersampling barely helped.
As a purely non room scale cockpit games only person I have no interest in hand controllers or super accurate roomscale tracking. 6DoF for driving and flight games will be perfectly fine. I honestly find it comical that many are declaring Rift and Vive as some sort of magical yardstick to judge all other HMDs with. Both have atrociously poor IQ issues and IMHO are in no way close to what is acceptable as an experience graphically.
When my Rift broke out of warranty I did not for one second feel the need to get another one. More often than not I much preferred playing my sims on a 4k 32" monitor. The clarity and IQ left the joke that was Rift CV1 unusable in comparison.
VR is a great experience and I want it again, but not the atrociously poor IQ of Rift (supersampling or not). For that reason the likes of the new MR devices with 1440x1440 or 1440x1600, or the Pimax 8K are far more intriguing to me.
Removal of SDE
Increased resolution
Reduction/elimination of god rays
Better FOV
These are what I will look for in my next HMD. The Pimax 8K should tick all of those boxes and is compatible with Vive lighthouses, so 6DoF is possible. The Samsung Odyssey also look very promising apart from the FOV.
