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.
I wasn't sure how you were installing it, if you were using something like a gog installer lutris for example could handle the installation for you, but sense you have it installed that's irrelevant
steam runs natively on linux though so no you wouldn't have to emulate it or anything
Without knowing more I'm not sure about the prefomance though, and I'm not an expert, but if you are dual booting it might have something to do with the file system you are using, I've not messed with dual booting before so I can't be sure, and I wouldn't know how to fix it either
I'm sorry, I've been confusing myself in the comments haha thought you were advising about how to get the windows version to run better now realize we're on Linux sorry!
So lutris is for running windows .exe on Linux! Good to know, and no I'm not dual booting yet just windows 11 just considering install Ubuntu/fedora or something to dual boot with and running cyberpunk from it instead of win11, or just going back to win10 and seeing if it helps
