Oh, so that is why everything felt slow when I went to F45.
I sysprof'd only to find my P-cores were completely silent and wondered "what is this madness?" given the historical context of burst-to-finish-faster being better.

Turns out, the new lpmd just straight up disables P cores in balanced mode. No intelligent balancing, just off.
Dope engineering y'all.
So if you're getting hella drop'd frames, there ya go.
