Have a Nvidia gpu and it works fine. The DX12 performance is not there yet but they are working on it and know what the problem is.
Do you not have contrast controls on your monitor? I thought every monitor in existence has contrast and brightness controls. If the colors look over exposed you probably don’t have the vulkan HDR layer installed. This is a known issue with Nvidia gpus because Nvidia has not added the vulkan extensions yet to pass the HDR metadata. If you have KDE Plasma, it inverse tone maps everything: desktop, games, ect.. It might not be as good as Nvidia’s implementation on Windows but good enough in my opinion.
