Desktop window manager is exactly what it says - if it's using a lot of GPU that means some visible windows or desktop elements are updating frequently which is causing it to repaint and do a lot of stuff. If you're running at a high resolution or have DPI scaling at anything other than 100%, or run games in windowed mode / borderless window or have any desktop overlays, screen capture stuff going etc... This is all going to put load on your dwm which translates to bandwidth consumption, rop saturation etc...

 

Edit: Also make sure this is actually an issue, is your card actually running at proper clocks when playing games or is it stuck at a super low frequency. This is a power saving mode, and if your dwm is using 30% of your GPU but your GPU is running at like 100MHz to preserve power then that's all fine. Could be that the card isn't ramping up when you hit it with a load. Check drivers in this case.

TLDR; DWM using a lot of GPU is a symptom issue.
