This looks like the panning performance issue that has been reported multiple times - Huge lag when panning camera
I’ve also noticed the same thing with this issue - it only happens on my RTX3060 laptop, but not on my 5-year old PC with 1080ti (maybe a 30-series drivers bug?) It could also be related to Resolution as the laptop is running at 1440p and the PC at 1080p. They’re both at Ultra but surprisingly I’m getting much smoother and consistent panning on the old PC. Framerate still drops there but no annoying stutter.
