Description Amarildo 2016-12-02 22:22:12 UTC
Just updated today and noticed a huge regression on X-Plane.
Mesa-git-87102.c45d84a works fine, but 87106.a7b510f causes the Sim frames to drop to 10 at certain areas.

I don't know how to bisect a git product, unfortunately, and the weather here in Brazil is hot and my processor would fry if I compiled for too long.
However, X-Plane offers a Free demo which you can try.

Downgraded to 87102.c45d84a for the time being.

Arch Linux

Was the perf regression fixed in later Mesa releases?

No response from original reporter so closing bug.
