Line 117:

this set up does carry one negative and it's that there's unavoidable high CPU usage by the X server while monitors are connected in this way. see the bug report here: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-470/+bug/1944667. swapping to discrete mode (and disabling prime render offloading), with the NVIDIA card set up as the primary output does away with this high usage, at the cost of having the discrete card powered on even once the external displays are disconnected. hopefully this is resolved in future versions of the NVIDIA driver.

== Non-NixOS section ==

The section currently suggests using NixGL.

In my limited experience, a more "convenient" option has been to symlink (e.g. via systemd-tmpfiles) the host's driver libraries to `/run/opengl-driver/lib` which is already in all executable's RPATHs, but I don't know how robust that is when it comes to libc. At least a mention of `/run/opengl-driver/lib` and RPATHs existing would be quite appropriate on this page.

I would also mention that on darwin `nix run` seems to work out of the box with opengl apps - for visibility
