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.
Downgrade to the 510 Nvidia driver. Runs absolutely solid on my rtx2080. It should be noted that this crash seems to be quite correlated to the rtx20x0 cards - my speculation is that something about dlss is a bit borked on them since they're the first dlss 2+ cards. It's not even exclusively Linux either, reports indicate that there's some sort of overlay (I blame the call overlay myself) that is tanking fps on windows as well. The 510 driver works great because dlss isn't available for it as I understand it.
