Hi, I was wondering if you are aware of any advantages of using CPU pinning with a multi-CCD Zen3 CPU (e.g. Ryzen 5900X and 5950X).

As far as I know only Ryzen 7900x3d and 7950x3d will be autodetected so I was wondering if I should manually set some values for the gamemode.ini's pin_cores and park_cores to get better game performances with my 5950X.

One more question about pin_cores: what values can be set besides yes and no? Is it possible to specify the CPU topography, for example setting that the CCD1 uses cores from 0 to 7 and the CCD2 from 7 to 15 or how can this parameter be used to do some manual core pinning when the autodetect doesn't work?
