I've been working on this video for a looooooooong time. Probably some of the most numbers I've had to look at and parse in a video before, I think I felt my eyes glazing over a bit by the end of it all. I had to do so many runs to validate results... This was even more exhaustive than the Crystal review, apologies if I let any minor errors slip through.

DFR's one of the most exciting things I've seen in virtual reality and man do I wish for it to be mainstream. Really hoping it catches on for some native support!

9/21/2023 EDIT:

For Pimax's DFR, it was discovered today that at some point recently Pimax screwed up on their UI and that the "Maximum" setting for Foveated Rendering is actually the LEAST aggressive setting, having swapped places with what should be the least aggressive(Minimum), where as what's labeled as the lowest setting is actually the most aggressive one. So these benchmarks were actually done with the lowest setting. Did some brief testing and the gains, in most cases, aren't too different but there's some instances where upwards of an extra +10-15%(Over the current foveated rendering numbers) can be seen between the least and most aggressive setting. This does, however, make DFR more noticeable under certain situations on the highest setting. I might recommend "balanced" as a general "set it and forget it" setting for most games if you don't wanna change it per game.

Pimax is aware of the issue. Will update this comment when it has been fixed. Will also likely be doing an updated video.
