I can't seem to run any of the "Platnum" OpenGL demos listed on http://appdb.winehq.org/objectManager.php?sClass=category&iId=95&sAction=view&sTitle=Browse+Applications. Even with a clean .wine directory they just crash with a dialog box that says an internal error occurred. I'm running Ubuntu Jaunty with Wine 1.1.28. Video card is nvidia 9500GT with 180.53 driver, direct rendering on and OpenGL 3.0.0. glxgears and other native OpenGL programs have no problem running. What other files need to be refreshed to simulate a clean Wine installation? I just rename my .wine to something else and then try to run these demos. Are there some other config files somewhere else? Could my problem be related to nvidia TwinView?
Removing or renaming .wine is all you have to do to start from a clean Wineprefix, but some games might install registry keys or files elsewhere that are REQUIRED by the game before it'd run, so you'd have to reinstall the game if you start from a new Wineprefix and then try if it works. Also, run the games from a terminal and post the terminal output here.
Tried emulating a virtual desktop as well as different audio drivers. Still the same. I always get this: Code: wine: Unhandled division by zero at address 0x7d72f376 (thread 001c), starting debugger... This happens a few seconds after running it, along with the Wine generated "program error" dialog box.
