I've been using an AMD 6700 XT for the past few years but have been considering getting a NVIDIA 5070 Ti for raytracing and lesser extent DLSS.

However, I've borrowed a NVIDIA 2060 and am having massive performance issues on the propriety drivers. I'm getting cursor stutters, window movements stuttery, Gnome overview stuttering, etc. Basically the desktop is not nearly as smooth as it is on AMD.

Even Nouveu is a better experience, although that means no Vulkan support unless I were to manually set up NVK.

Is the experience any better for 30 series or 40 series?

Edit: After further thought, I think I will just go for a Radeon 9070 or 9070XT since it's the safer choice; FSR4 seems to be a big upgrade (though I never noticed any major issue even with FSR1), open drivers, and since it will likely be significantly cheaper to get 16GB of VRAM.
