I spent around 2 hours doing everything you told me, following all the instructions, the games performed fine under all the parameters, so I guess this is a Windows 11 problem? The instructions were complicated but I'm very confident I did what was asked, I couldn't find a problem in either half of my programs so there wasn't any need too wittle it down until I found it, it just wasn't there.
I've just performed a normal boot and my games right now are fine but they wont be in around 20 mins, it seems my system can't change game once I've been in one for a little while. I wasn't confident that a start up program would be the issue as the issue doesn't actually accure until I change game shortly after playing one.
I'm willing too completely reset my computer if its guaranteed too solve the issue, if that is a thing, thanks
