Trials 2 is a DX9 game, so I had to enable the DX9 trick to get it past it's hardware check, otherwise it just complains about the hardware not being enough. It then brings up a simple settings screen with graphic and audio options. I can get that far, but after hitting the Start button to play nothing happens. I saw a wine process churn up the CPU for a short time but otherwise nothing happens, no window, sound, no indication that it was ever opened.
This may be related to my hardware, a Mac mini with GMA950, the game works fine in Windows at least. I have no other hardware to test it out on unfortunately, hopefully it works on better stuff.
