Re: Dwm.exe Desktop window manager is eating up my GPU

I think Microsoft sending you here is like saying "I don't know.  Go away".  The slowdown is within windows.  I don't know how much main memory you have or what you are using for a disk drive, but those are the 2 areas that provide the most general improvement in speed.  More memory is usually the first and easiest thing to try.  Memory can cut down on how often parts of the game or application need to be fetched from disk (paging) and an SSD can speed up whatever disk access is needed.  


The reality is that your machine is 3 or 4 years old and games are designed for the newest and fastest hardware.  Last year (2018) the CPUs got a lot faster for the first time in several years.  Games designed for that hardware will not appear as smooth with a system built before that time.  I'm not suggesting you run out and buy a new computer.  It is best if you can run some sort of graphics benchmark program and see if the kinds of things you do get faster.  For general graphics rendering, I like Furmark (freeware)
