I have both a modern Radeon and Nvidia card in my PC.

Radeon overall offers a smoother desktop experience, and works fine with gaming, including proton-enabled games on Steam. OpenCL via rocm works decent, with some occasional crashes, in Darktable. Support for AI-frameworks like jax is however very lacking, and I spent many days struggling to get it to work well, before giving up and buying a nvidia card. geohot's rants on X are indicative of my experience.

The nvidia card works great for AI-acceleration. However, there is micro-stuttering when using the desktop (gnome shell in my case) which I find extremely annoying. It's a long-known issue related to the power manager.

In the end, I use the nvidia card as a dedicated AI-accelerator and the Radeon for everything else. I think this is the optimal setup for Linux today.

I use KDE plasma and experience no microstutter with a Nvidia graphics card. Is there an open gnome issue for your issue on gnome?

I think it has something to do with the power management on NVIDIA card. When actively using it things are fine, but there will be a stutter when activating Activities or switching workspaces.

I've tried using the triple buffering mutter patch[0] and still was experiencing issues. COSMIC is looking great but I have some weird screen artifacts randomly.

Hyprland is the only environment that hasn't had any performance issues with my 4070 Super.

I'm not sure, but I've found a couple of reports at nvidia's linux forum and their github issue tracker. This is with the open source kernel module & wayland. It's possible that X11 with the closed source module works better, but I prefer wayland.
