lucky me, i’m running mitigations=off and smt=off on a 7950x.


Out of curiosity did you have smt=off for performance reasons or other reasons?


performance testing vulkan and physx on linux.


Note recent reports of mitigations=off _hurting_ Zen4 performance in many cases.

I don't have Zen4 so I'm not super up-to-date on this -- r2-t2 above disagrees, but offers no data.
