I didn‘t Upgrade to the Beta 21H1 Version but tried to turn HAGS on, which I had always turned off since now. This gave me less stutter and a smoother feel and I‘m very surprised of that, because i had this always turned off like it was suggested by the most people. I use the latest driver 461.92. OXR and Nvidia driver settings are default. I have a 10700k CPU und Nvidia 3070 Card, 32 GB RAM and Nvme SSD‘s. So give it a try.
