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.

DLSS is upscaler. Game is rendered at lower resolution and then image is upscaled in a bit smarter way than simple "stretching".

More precisely, DLSS is a set of models that use AI to interpolate an image. This interpolation can take many different forms:

Interpolation can be used to take a lower resolution image and upscale it, which is the main feature of DLSS.

You can also use DLSS to take a high resolution image and scale it down, with less artifacts, as a type of antialiasing. This is DLDSR.

You can also use it to take information from an image, combined with motion data, and interpolate how blocks of pixels might change into a new frame. This allows you to generate intermediary frames. This is Frame Generation.

You can also take a very noisy image, composed of discrete dots, and interpolate how neighboring pixels should look. This is Ray Reconstruction.
