Visable performance regression in sauerbraten game

[Maxim Levitsky]

Tested revision just before texformat-rework, and everything was fine,
after there few revisions that won't work, and then I notice significant
speed reduction, and hiccups.

Tested with default settings + 800x600, Intel G965

Best regards,
Maxim Levitsky

Is there a specific test case or application that shows the regression?

To reproduce, just start the sauerbraten game.
I play now the version in ubuntu 9.10 (0.0.20090504.dfsg-1)

I tested the 'Private stan sauer', part 2 (run and guns ||)
Here attached version of configuration I used.

With this regression, I see frequent hickups, that make the game almost
unplayable.


Without the regression I get about 18-24 FPS.


I bisected this bug (and tested successfully master branch with this
commit reverted)


2c30ee9bd69ed606b984c051748a7cdb34905eeb is first bad commit
