Except that in this case, it is due to a bug in id software gameengines. One of the first things the software in Quake 3 (and alsoQuake 2) engine do, is to ask for the openGl extensions supportedby the graphic driver. It also sets aside a memory buffer wherethe reply from the driver (a list of extensions) are stored.These early games didn't anticipate the number of extensionsthat would be supported by subsequent versions of the API. So youeither get buffer overrun or seriously cut down list of extensions(if the application writer at least checked for a max limit) whicheither crash the game or affect regular functioning.I downloaded Return to Castle Wolfenstein source code, to fix itmyself and the problem was obvious. Actually, the code even hada comment about the buffer size not enough for future compatibilityand someone had arbitrarily increased the size about two orthree times as a quick workaround.When nVidia released OpenGl 4.0 support, their customers ran intoexact same problem. Quake 3 games stopped working. To their creditthough, they fixed the issue quickly by detecting the applicationand then only sending extensions supported by OpenGl 2.0. ATI's10.10e (hotfix) drivers do the same and most Quake3/2 games work(with Call of Duty as the only big exception)Until ATI added fix for game engine's shortcoming, the workaroundwas to copy atioglxx.dll (from Catalyst 10.4 and before) into thegame directory. I am not sure why that method stopped workingfor Trimble. Currently I have three Quake 3 engine games installed.Alice and Quake 3 (both original and Live) run fine without anyissues on 10.10e driver, and Call of Duty requires copying the dll file.My 2--Noman
Last week CodeWeavers had released CrossOver Games, which is a more frequently updated version of their CrossOver Office software and is optimized for use with Windows games. If you're still using WINE directly, however, you'll be pleased to know that a new release is out today with a number of changes. WINE 0.9.59 has improved support for Microsoft's .NET framework, improved service handling through a separate services.exe process, support for ATI's fragment shader, improved support for HTTP proxies, window management fixes, and pre-compiled fonts can now be found in the WINE source tree. In addition, there are also a number of bug fixes. Head on over to Wine HQ for the full change-log and download links.
