I never had good performance with the Nvidia GPU.
Before, I was using the integrated Intel GPU which had fair performances, I only had a rolling barrel-like effect in videos … but nothing shocking.
Since I installed the Nvidia GPU, I never had good performance on Gnome/Wayland. Neither with the non free driver nor the nouveau driver.

Just to had more details, my Dell laptop is also on Nixos (23.05), with Optimus architecture (intel+nvidia).
The basic setup is just perfect. The screen is recognized and configurad to 100Hz, performance are just perfect.
