I meant the GTX900 series. I’m aware the 700s have decent support in nouveau, but the 900s has already been dropped by nvidia so we are on older drivers not capable of the latest vulkan extensions required by modern Proton.
For nouveau it needs GSP firmware that wasnt released as part of that release they did a while ago. I think pascal users are on the same situation, they just havent been dropped by the proprietary drivers yet. I wonder if we are gonna be stuck on xorg forever.
The newer cards got the important bits released by nvidia so the community can at least have a path forward…
