--- Comment #3 from Gerald Folcher geraldf2@free.fr 2007-08-21 11:59:00 --- I experience the same (or at least very similar) slow-down bug with this game, but on my system it happens only rarely. I don't know how to reliably reproduce it, for me it only happens semi-randomly, when it happens it seems to be mostly at the start of a race against AI drivers, or when loading a track (still in the menu), and when quitting the game (see 3rd paragraph below). I have the impression it may be related somehow to high CPU load (but I don't know really).
It's specific to this game, I didn't have any such problem with any other Linux or Wine game.
I regularly run the game at 800x600, 1024x768 works too but probably has more chance of triggering the bug. USUALLY the game works very well, but I have a GeForce4 Ti 4200/128M gfx card, which, despite being older, AFAIK is faster/has more memory than Xwang's, so maybe that's why in my case the problem is not triggered easily with higher resolutions. While I'm at it, my other system specs are CPU: Duron 1.8 GHz, RAM: 512M, nvidia proprietary gfx driver v1.0-9639 (I had the problem also with v1.0-9631 too).
Also I'm not sure it is the same problem but, it happens more often, when I quit the game and there's the screen with the rolling credits, if I let it rolling (not hitting a key) for some seconds, it often suddenly slows down and/or halt and I have to Ctrl-C Wine (Because of this I've taken the habit of immediately hitting Esc when this screen appear, but sometimes I'm not even fast enough), it may be interesting to note that this simple rolling credit screen eats up 99% of my CPU (according to 'top').
Also, maybe it's unrelated but the game (on Windows) seems to be touchy when it comes to CPU stuff, look at this FAQ: http://forum.racesimcentral.com/showthread.php?t=105748 (search the page for "cpu")
