Question Intel i-9 14900k vs DX12

[mmolitor357]

Hello, so a lot of my games have been crashing when launching the m or straight up won't even load. And some games that do work will only work on DX11 and not DX12. Recently I saw a thing where if you lower the performance core ration to under 55x, that things will start to work. I did this and set it to 54x instead of its factory setting at 57x. Everything immediately started to work fine, no problems at all. So, my Questions are why is this? Also does changing it from 57x to 54x give me less performance in games and how bad?
