I don’t think it’s Wine / Proton, but who knows…
Looks like driver / vulkan issue to me, Proton / Vulkan / DXVK doesn’t seem to understand your hardware:
5855.790:00c8:00cc:err:vulkan:wine_vk_instance_load_physical_devices Failed to enumerate physical devices, res=-3
5855.790:00c8:00cc:err:vulkan:wine_vkCreateInstance Failed to load physical devices, res=-3
Since your Nvida card supports Vulkan, it should be some mess with drivers.
I’d start from scratch:
- Use LTS Kernel for full Nvidia support
- Follow that guide for proper driver management with Optimus, it’s the best way to have sanity:
Optimus Switch - Another Solution for Optimus Laptops
But before that, just please make sure again that you have all those packages installed:
sudo pacman -S vulkan-icd-loader lib32-vulkan-icd-loader vulkan-icd-loader lib32-vulkan-icd-loader
And try again
