Hi Grzegorz , please remind what Linux distro you're using and how fresh is its' drivers/software. AMD drivers really improved during the last couple of years, but if you're running some ancient "debian" - of course GPU performance is lower than expected. Myself, I'm currently using Artix Linux - while it has a really fresh software (just like Arch), it almost never breaks, and doesn't have a SystemD (good for you if you don't like it as well).
