Hey, so I don’t know if anyone at Nvidia is aware (I imagine they are), but Cyberpunk 2077 requires the VK_VALVE_mutable_descriptor extension to run without crashing on Linux via Proton. The Mesa vulkan-radeon driver for AMD GPUs has implemented the extension, so the game now runs on AMD GPUs. And while the game will launch on Nvidia, it will crash after a period of time due to the missing extension.
Please, if you could, get this extension implemented in the Linux drivers (if nothing else, at least the Vulkan beta driver). I’m sure the vkd3d-proton guys over at the VKx discord (or their github https://github.com/HansKristian-work/vkd3d-proton) can surely help with more information as needed.
