SteamOS vs Windows 11 on my $100 Graphics Card

I recently picked up an old RX 590 for £75 / $100. It's not bad for budget gaming in 2026, but I wanted to see if running SteamOS instead of Windows could fix it's problems, and maybe run better? Test Specs: i7 13700F 32GB DDR5 6000 RX 590 8GB Steam OS 3.8.14 Windows 11 25H2 Thanks for watching :)
