Or less: Re-Testing Windows vs Linux in 2025 - AMD & NVIDIA Gaming Benchmarks on average of 20 DX12 games. Actually there are games that are more impacted, and probably this is system related. For some reasson Ancient Gameplays in their test had one of the lowest average loss (15% at 1080p, 10% at 4K).
Bottom line: I still prefer freedom and play at “only” 87 fps than having a giant spyware and play at 120 fps. Does not mean this should not be corrected of course.
