How to improve gaming performance?

I have just bought Grand Theft Auto San Andreas, which runs beautifully on my XP install, but on my ubuntu9.04-wine/stable install it runs very very very jerkily. Unreal tornaument works better in wine thanit does on windows so yeah. And ideas how to improve the performance? Ive done the directx registry edits, not much of a change.

start it with the prefix "WINEDEBUG=-ALL" before your execution command, thus disabling all debug output - some games can be accelerated quite a bit that way.

My total system specs if you like

AM2 AMD sempron 1.6ghz overclocked to 2.5ghz
2gb ddr2-667 oc'd to ddr2-800
XFX Nvidia Gforce 7600GT XXX edition
Biostar MCP6P-m2+ motherboard

The debug thing didnt make much of a difference, so ive switched back to XP for the time being

Set OffscreenrenderingMode to fbo (search on the wiki) and disable
pixel shaders if needed, it will run like a charm!

I've heard that anecdotally, but - do we have any solid figures on this?

i.e. could someone with a pile of games please list for us their
before-and-after numbers?

It highly depends on how much noise there is.

If game prints 100s of lines per frame, that will be huge. Also some distros/setups redirect all X output into a file... You can guess how big it will get over time and how much it will slow things down.

At least on Ubuntu, all output gets redirected to /home/(user)/.xsession-errors for general degugging/basic system information/etc. Once the .xsession-error file gets to 195KB it ignores anymore output,or input into the file if you like. I think this sort of thing is all subjective, it runs faster(?) because you think it runs faster.

There are definite cases of terminal output slowing applications down.
To simulate it, try running your app with +all.

It doesn't happen often, but can. Especially when games follow
unexpected paths and lots of err's are produced, or a path is hit
repeatedly with the same fixme over and over.
