This seems to go away when doing a perf/cpu profile, it might do something with process priority that fixes the problem? Regardless, in all profiles I see some 15-20ms frames on my fast CPU (12th Gen Intel(R) Core(TM) i7-12700KF 3.61 GHz) which will be much worse on the average machine.

I can reproduce, it's much smoother while profiling but still we have tons of frames running more than 50ms
