I have taken pleasure in pushing my VR experience to the max for 1 year now. Started with RTX 3090, upgraded to 4090 in November. You can get enough frames to turn off motion reprojection (also known as make things blurry, and give everything an underwater effect). BUT the problem is there isn't a SOLID way to lock frames at half the framerate of my 90hz Reverb G2. So you get micro stutters ALL THE TIME. With a 12900k + 4090 at 45fps.
This riva magic thingymadoodle is INSANE. I've literally been searching for this solution for 3 months. It doesn't completely fix the stutters but I'd say it makes things 80% better, which is completely incredible. I am SO happy. Thank you so much. I will be making a video about this.
