The YouTube channel “Maximum Fury” conducted a technical test of the new Cyberpunk add-on called “Phantom Liberty” on an older AMD hardware system, testing it separately on Linux and Windows 11. The Linux system, specifically the Fedora distribution called Nobara, performed significantly better, delivering 31% more frames compared to Windows 11.
The hardware used for testing included an Asrock B550 motherboard with an AMD Ryzen 5 5600 CPU and an AMD Radeon RX 5700 XT GPU from the first RDNA generation, along with 16 GB of DDR4 RAM. The CPU, RAM, and GPU were overclocked, and the system utilized undervolting to save energy costs.
When testing the game at 1080p resolution with high textures, the Linux system achieved an average of 63.72 frames per second (fps), while Windows 11 managed only 48.55 fps. This suggests that the game should run noticeably smoother on the Linux system.
What are the chances that it’s just not rendering something due to the DX12 to Vulkan translation?
Possible, but looking through the footage it seems everything is being rendered as expected.

It’s entirely possible that the translation layer will alter timing to expose a race condition such that something doesn’t render.
DXVK doesn’t support DX12 and wouldn’t be used here.

But that’s not exactly relevant.
DXVK 2.2 added D3D11On12 which could probably then be used by VKD3D or D3D12 so I suppose it does support DX12 indirectly.
However DXVK itself doesn’t support DX12 native games like Cyberpunk 2077.
