I suspect a good chunk of the difference is due to WINED3D_CS_SPIN_COUNT being unreasonably large, which is something we're already aware of and should have a solution for in the near/medium term.
Fundamentally Fabian is right though; higher CPU utilisation isn't necessarily a problem if that results in better performance. FPS/frame time is one measure of that, but you'd want to look at GPU utilisation as well.
my tests yesterday were done with cmst enabled. Disable it allows to have a lowest cpu-load and temperature. I thought csmt was related to OpenGL only.
I tried to do a graph for DXVK/DAMAVAND (with csmt disabled)
