=== NVIDIA ===
NVIDIA do not officially support accelerated video playback on Linux. A third-party implementation exists, but does not support Chrome<ref>https://github.com/elFarto/nvidia-vaapi-driver#chrome</ref>, and has significant limitations compared to the other implementations<ref>https://github.com/elFarto/nvidia-vaapi-driver#codec-support</ref>.
NVIDIA users with a separate iGPU should generally prefer to use their iGPU for this, and therefore look to the above Intel and AMD sections instead.
Users with only an NVIDIA GPU can attempt to use the third party implementation; the package is added to <code>hardware.graphics.extraPackages</code> by default, but it requires some additional setup to be useful<ref>https://github.com/elFarto/nvidia-vaapi-driver#configuration</ref>:
