Your i5-9600K is powerful, but it might struggle under heavy gaming loads if your graphics card freezes frequently.
Have you performed a complete Windows reinstall? Are the games displayed in full-screen or borderless windowed mode?
From what I've learned, Windows 11 might actually reduce performance even after major updates. Reinstalling Windows could be worth considering if you want improvement.
You may encounter a driver clash with the drivers from your previous motherboard. You can obtain new M.UI drivers from the website if you haven’t done so yet. A system reinstall is usually suggested to prevent issues, though it might work after applying the updates.
