Found this very good video around Lasso and AMD 3D cache perf, you might be interested it … (Has EN subtitles from the CC menu)

That was an interesting video. My biggest takeaway was that the 7950X3D performs best in two scenarios:
- Game Bar ON, no Process Lasso, ‘Balanced’ power plan.
- Game Bar OFF, Process Lasso to set CPU affinities, ‘High Performance’ power plan.
The latter being slightly preferred (although I’d like to see a CapFrameX comparison of 1% and 0.1% lows.)
For the 7800X3D (and presumably the 5800X3D) Game Bar ON, no Process Lasso, ‘Balanced’ power plan.
This contradicts my current understanding, but he seems knowledgable. More importantly, he did some actual testing.

Interesting. Its a year later and MSFS has seen some optimisations, on my 7800X3D (SMT off when i tested it), MSFS used all cores but core 0. Will test again as i have SMT on now again.

MSFS as been using all 8 (+8) of my cores for over a year
haha, weird. I gotta check tonight if that changes with the SMT on now.
