Caused by #111915, FYI @amanasifkhalid. Only one commit in the range. Larger regressions on older hardware with newer hardware having a decent bit less.

Larger regressions on older hardware with newer hardware having a decent bit less.

@LoopedBard3 what's the difference between these two configs? Just wondering if the former is affected by JCC errata.
