Clean install display drivers massively improves VR performance!

I tried running 70/100, huge mistake,it basically locked up , wouldn’t let me toggle in and out of VR, just sat there in WMR. couldn’t get control of mouse. had to shut FS2020 down with task-manager. Set it back to 70/70 and all is good but with a bit of smudgy cockpit graphics but certainly playable. I can always lean down and read the glass cockpit. I have a 6800K with a 2080Ti, which certainly is no Kingpin 3090. I have my OpenXR set to the “Automatic” setting as opposed to disabled, could that have caused it? Or should i go to something like 70/80 or 70/90 or would that even handle it… I would hate to keep shutting it down with task-manager in fear that I’m going to corrupt something and have it start doing CTD on me. By the way, when I’m in game, my CPU is not maxed out but i noticed the GPU was pegging up pretty high like 89 to 95 percent at times (70/70) . My 6800K CPU is running at 3.9999 GHz and I’m running the game on a Samsung Pro M.2 SSD w/32GB RAM. ALSO, and this is a big ALSO. After running the game for longer flights 30 min. or so, i get a freeze up (computer is NOT froze, i can click and run anything on the desktop) in MS FS2020 only and it takes about 1 minute or longer for it to come out of the freeze, but if I wait, it always comes out of the freeze. Could that be that I need to clear the Shader Cache or would that just cause even more problems? What else could i look at to possibly lead me to the answer on the freeze ups? It’s starts to do that freeze up more and more the farther I’m in to my flight sim sessions. I’ve looked at other processes that are running…just can’t figure it out. Maybe i’ll look at task manager during the next freeze and see if the GPU is clocked at 100% ? or CPU, but I doubt it’s CPU since I can do anything I want in WIndows 10 during the flight sim freeze out.
