+### GPU passthrough pour VMGaming
+- La configuration `VMGaming` est optimisée pour une VM Proxmox avec GPU passthrough.
+- Le profil actuel active les drivers **NVIDIA** dans `configuration-vmgaming.nix`.
+- Si tu passes une carte AMD, remplace `services.xserver.videoDrivers = [ "nvidia" ];` par `services.xserver.videoDrivers = [ "amdgpu" ];` et retire le bloc `hardware.nvidia`.
