Low fps caused by windows 10
Low fps caused by windows 10
It could be an initial setting that wasn't designed for Windows 10, but I'm fairly sure it relates to DWM. If you noticed recent releases in the last couple of years, you'd likely see "Exclusive Fullscreen" available. The change happened because "Exclusive Fullscreen" became necessary due to DWM's strong influence and developers finding ways to bypass the compositor entirely by using this mode. Whatever the issue with MW3 is, I'm pretty sure it's not something that can be easily fixed or adjusted. Also, the developers might have noticed general performance problems after players started using Windows 10, even five years after launch, and could have made a simple fix to cap FPS.
I also had roughly the same goals for solving this issue, and I thought it was worth seeking advice. If anyone could clarify the exact causes, it would be really helpful.
