yes just 1 specific boxing window, I have the video settings to lowest on that specific window, normally all 5 are on good with no issues.

Anyway I ran the cpu wizard, don't remember now what it was on before, I tried a couple of different ones and now it works fine.
It was on one of the ones that assigns cores to each client or something, think somehow it didnt like whatever it was on, somehow.

now video settings are back on good and fps is around 30

So somehow the cpu assigned meant was causing an issue because its good as gold now.
