Well that's good. Though still a little disappointing you can't run an old QC comp....
I was checking out your turntable, nice work. I can definitely sympathize trying to recreate QC stuff.
Yeah, event throttling vs enqueue events probably wouldn't help much for your low fps situation. Came up for me recently trying to build a list of cubes and pass shaders to the built list. The cubes in the built list were missing some shaders because the enqueud list of shaders wasn't making the journey from a subcomposition made for the six sides of the cube, showing some with checkerboards. Switching to drop events fixed that one.
