The patch can make TA a lot faster the problem is that the game crashes because it becomes multithreaded. Command&Conquer (which crashes when you move the mouse) felt a lot faster, further StarCraft is a lot faster too. When the multithreading issue is over TA will most likely be playable on your system.

I fired up Total Annihilation just yesterday with Wine 0.9.2 and it was very slow. TA uses 8bit color and I'm running in 24bit at 3200x1200 (2x 19" CRTs) on a Pentium II 450Mhz with a GeForceFX 5900XT -- a bit of an odd combination... I know. If you'd like a speed comparison, perhaps with associated CPU usage I may be able to oblige.
