Summary: Major performance regression for AMD card
Product: Mesa

OS: All
Status: NEW
Severity: major
Priority: medium

With the latest git mesa, there are major performance drops. First noticed the
issue with the 32bit steam game "Move or die", but it seems to affect the whole
system. It basically makes the game unplayable.
Bisecting pointed me to the following commit:
