Unfortunately, it doesn't look like the final release of Fedora 34 received the support for accelerated 3D graphics on NVIDIA's GPUs. This is not the fault of the Fedora, GNOME or Wayland developers; the blame for this falls squarely on the shoulders of NVIDIA for not opening its drivers. Because of this, if your desktop (or laptop) uses NVIDIA graphics, you'll be relegated to the older, slower
X.org. That is such a shame. NVIDIA, get the hint already.
