Title: 9950X3D2 Core Affinity
Post by: Adenoid on July 28, 2026, 12:11:48 AM
Any X3D2 owners out there have weird thread scheduling/affinity behavior? New build, 9950X3D2, new Windows 11 Pro install, latest BIOS on an X870E-E board w/ latest chipset drivers. Random games will be set by Windows to CCD2--if I look at the affinity they are set to core 16-31 only, 0-15 are disabled. This isn't the usual thread scheduling you'd expect to see (all core affinities enabled, but just 0-15 being used for games). The games that are affected are completely random as well. So far I have seen it with Nioh 3, Grim Dawn, Alaloth, and King Arthur Legion IX.

At least with Nioh 3 the performance is crippled to being unplayable--about a 30-40% performance hit with wild fluctuations--unless I open task manager and change it to all cores (works normally if I do that) or use Process Lasso.
