I experienced stuttering and screen tearing since SU12, using the latest NVIDIA driver 531.41. I have a 4080 GPU and am using DX12 with DLSS.
NVIDIA have introduced a hotfix driver, which I installed yesterday and, based purely on one flight in the Bae146, the stuttering and screen tearing have gone. Early days but so far I’m very pleased with the improvements.
