Thank you very much for this extra info. I will pass it along. I hope we can find a solution...

Do things improve with a clean OS start?

Do things improve with a clean OS start?

An on/off power cycle of the computer does not change anything.

I have not tried a clean macOS reinstall. Is that something that might help? If so, would I need to reinstall everything onto the computer from scratch or would using a Time Machine back-up after reinstalling macOS work the same?

I can see in the Activity Monitor that the WindowServer function is also using quite a bit of GPU resources. The amount fluctuates but at times it accounts for up to 50% of GPU usage according the percentage stats in Resolume. If Resolume stats show 40% GPU usage in the Activity Monitor Resolume will account for 20% of that and WindowServer accounts for the other 20%. If this is relevant I can take a look at what the WindowServer uses while other apps are running, I haven't checked that yet.

The actual FPS is still high though, right? so the GPU can do what it needs to.

Set to Auto the FPS is fine and set to 60 it holds with only occasional dips to 59.

Set 50, 30, or 25 and the FPS stays 1-2 frames under the set number. With each lower FPS setting the GPU usage drops as well. At 25 FPS the GPU rocks around 20%, the same content at Auto FPS runs the GPU around 80-85%. My comps have pretty much always been set to Auto so these may be normal results.

Indeed, lower FPS would mean lower load and less GPU usage.
