Ya, it does not appear to do anything with the Q1. Maybe because it's being done with the Q2 headset chip? This has never been explained properly by Oculus. Pretty well the only way to improve Q1 clarity is with super sampling. The amount you can use depends on your PC specs, esp. your gpu. With my rtx3090 I can take this up to 1.5x and it looks pretty good. Still not as good as my Q2 at 80Hz with res slider full right.
I really love my Q2 wireless with Air Link but my Q1 still works and looks a little better wireless with Virtual Desktop. Even better than Link, for me anyway. I've recently given away my Q1 and Link cable to a flight sim buddy of mine so I'm now only using my Q2 with no regrets.
