wine users - Jun 2010 - getting l4d2 to run better?

Hey guys,

I'm running ubuntu 10.04 on wine 1.2-rc3 on a Asus G73JH Laptop. Ive gotten
steam and l4d2 to install and I can run both, but while in game with l4d2, it
runs okay at certain points but then studders/slows down when the action ramps
up. Is there anything I can do to improve the performance so its more playable?
Thanks for the help.

Maybe you can put you game in low quality mode ?

Force the game to run in DX 8 or lower in the luanch options , i did this with
CSS and it boosted my fps to about 150-200

-dxlevel 81  

or use 80 or 70
