Caporegime
Windows seems pretty decent at this now. Whenever I'm gaming on my 7950X3D i can see it park an entire CCD without issue.With two Vcache CCD's, the OS only needs to keep the game on a single CCD....*any* CCD.
When the extra cache is only on one of the two CCD's, the OS has to first pick the correct CCD and then *also* make sure it keeps the game on that *specific* CCD.
