Installed the latest Windows (version 2004) yesterday as soon as it became available to my pc. Several reboots later everything was fairly stable. Most racing apps ran fine including SimCommander and the NLR Motion Platform. VR on the Oculus Rift S was fine; however, I did notice a decrease in frame rate in a lot of my games. So, I downloaded the newer standard nvidia WHQL driver for guru3d.com. Once installed, minor problems occurred with games crashing at random points. I disabled the realtek HD audio manager. Things got better. I tried enabling g-synch in the nvidia control panel. Things got worse.
I did not bother with Hardware accelerated graphics scheduling (HAGS) as it doesn't appear to be ready for prime time according to most of the folks at guru3d.com.
Anyway, to make a long story short: After installing the newer standard nvidia drivers, I had to go back and downgrade the drivers to the prior nvidia DCH WHQLs and turn G-synch OFF in the nvidia control panel before I could get everything to run without crashing.
For reference in Windows version 1909 at 3840x1440, I was running at 70 FPS (without OC'ing the graphics card) in Forza Horizon 4. Now I am running about 65 FPS. Still good enough to enjoy but a bit of a let down. Ironically, FH4 has always been the finickiest piece of gaming software I own. Once it runs without a hitch I know the rest of the system is fine.
As for the Oculus Rift S, still stable 79-80 fps in AMS2, ACC, etc.
System specs: i9-9900 conservatively OC'd to 4800 ghz due to high ambient temperatures, 2080ti (undid overclock for Win 2004 to sort issues) , MSI z390 Gaming EDGE AC with wifi, 16 gb ram and two 1tb SSDs.
Sim racing goodies: GTTrack, Accuforce Pro v3, Clubsport v3 pedals, NLR v3 Motion, TH8a H-shifter, Fanatec handbrake, Oculus Rift S, and 34 ultrawide monitor.
As always, these OS upgrades tend to be risky. For me, it was largely successful. Hope it will be for the rest of you.
Good luck to you all!
