egon2003, please open another bug for specific issue.
This one is related to only 32bit some apps run much slower, compiler so gcc
involved, libc maybe... that sort of things.

I updated my videocard bios and that made everything a lot better, still some
minor drops here and there but for example Unigine Heaven runs as it should
now.

OpenJK even with -O0 is ~2.5x times faster then -O2 -mtune=generic :)
Anyway, just found code example from bug 83442 is useful here too, so maybe
more people can easely test if they are affected.

OK i found -mtune=generic is culprit for performance :). Played a little with

-mtune=i586 = slow
-mtune=pentium = slow

Default what Debian 32bit passes in addition to mesa options is:

Actually nothing to do with the -O3, but with the -mtune -march it seems.
On Debian default is -mtune=generic -march=i586 maybe that is the problem, if

Yes, it's 64bit for sure.

to compile it myself.

performance decrease, I should have made it a bit more clear, sorry.
