Performance issues with Intel Arc A750 dedicated GPU
I think this issue might be known to some degree, but there's no issue for it in the issue tracker. I've seen complaints about this elsewhere.
OpenMW performance is noticeably worse with a dedicated Intel GPU versus an AMD GPU. I had no performance issues with OpenMW when my system used an Radeon 580 GPU. It wasn't until switching to the Intel Arc A750 that I began to run into issues.
Frame rate rarely goes above 60 when standing still in exterior cells, and when profiling the performance with the OpenMW profiler, I see a big drop in draw call performance (-50% frame rate) when panning the camera around versus standing still.
