I have a nix flake for bevy located here
https://github.com/NexusSocial/skilltree

But when I use it, it gives me this GPU missing error, anyone here use Nix Flakes with Bevy and Nvidia GPUs if that is the specific issue?

Given this is Nix you should be able to reproduce the issue pretty easily lmfao

There is a problem with nix and rust regarding graphics API I remember setting some flags in the build script I found it on GH but I can't send you exactly the solution as I'm in travel rn

Btw hello fellow nix user

Unsure if the issue, but this trips me up sometimes: is your nixpkgs input of similar age between your bevy flake & your system flake, don't think graphics libraries get the same level of nix goodness & some bits need to be system wide, so I find I need to keep them sync'd to some degree, so the client libs match the system wide ones.
