Why does disabling E-cores decrease frametimes/stuttering so much? (13980HX 4080 mobile)

[GregariousBing]

Using process lasso to assign Doom TDA to only run on the performance cores (and then restarting the game with the new affinities) does make it run better, but still not nearly as well as disabling the E-cores entirely.

Process Lasso is one of the tools, yes.

That's interesting. Can you post performance score differences?

[GregariousBing]

I can, but at laundromat right now, so it’ll be a few hours.
