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.
casusally skipping millenium edition because most people opted to buy windows 2000, the enterprise server os instead.
Windows 2000 couldn't run games because it was based on Windows NT and the NT Kernel. ME was still based on DOS. XP frankensteined the NT Kernel and DOS to somehow make the most stable, longest running and best windows ever.
And 20 years later they're bleeding marketshare.
Windows 2000 could run games (I should know: I kept being a gamer whilst using it for years) but in the early days with so many games designed for DOS that required direct low level access it was a problem. If I remember it correct one had to boot in DOS mode for those.
Eventually with DirectX that stopped being a problem (plus, again if I remember it correctly, OpenGL also became compatible with it).
