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.

This is likely going to change as software support for gaming on Linux improves.

If you consider real high performance computing, with well optimized libraries that can properly use the hardware (including GPUs), 50 % difference between windows and Linux is not really surprising. This is the reason 100% of real high performance computing is done on Linux. It is a better OS for raw performances than windows. For some tasks we are easily talking over twice the performances. It is not always the case, but not surprising at all.

The differences clearly depend on the actual low level implementation of the code. But in general the current situation in gaming, with windows that competes with Linux on raw performances, is only due to lack of software support for gaming on Linux. As this is changing over time, we'll see games performances greatly improve in Linux. Hopefully until the physiological surpass of windows performances.

Currently most of gaming support on Linux is done via some kind of translation layer, that has itself an overhead. It means that the real linux performance would be even better than in all these benchmarks, if it was really possible to compare 1:1 Windows and Linux with native, well optimized code.
