On Intel HD 530 (8086:1912) for 10000 fish I get

chromium-109.0.5414.119:
- 41 FPS under Sway
- 60 FPS under Xwayland
- 60 FPS under Xorg (modesetting, without compositor)

firefox-109.0.1,2:
- 30 FPS under Sway
- 31 FPS under Xwayland
- 29 FPS under Xorg (modesetting, without compositor)

Maybe Firefox uses DMABUF[1] outside of Wayland and VA-API nowadays.
If so for DMABUF to work on NVIDIA GPUs you need DRM[2].
