-## Troubleshooting

-### "My external monitor is very laggy on PRIME"
-
-This is a known NVIDIA driver issue. You should have the latest NVIDIA
-driver installed and use Wayland with a compositor that supports explicit sync.
-For GNOME this has been fixed in version 46.2. For Plasma 6 it will probably be
-fixed with 6.1 although some users report normal performance already on 6.0.
-Other environments/window managers still have this issue, so you need to switch
-to the latest version of GNOME or Plasma to fix it.
