Ok, I received a Vive base and now I can say “OMG” officially It is not only working well, it is best tracking I ever had compared to oculus and WMR, because I’ve not noticed any drift at all.
There are some things that could be better, and top of my list would be: a) Smart Smoothing is unusable in rFactor 2 (so I hope it gets improved) b) I believe I have one dead pixel (always blue). AFAIK this also can happen with LCD monitors, so I wouldn’t take this as a negative reflection on Pimax 5k+. It is also impossible to see while actually using the device in game.
Other than that, racing with high FOV/resolution is amazing!
