There is a known problem with Quake 3 engine games which use the OpenGl method in that ATI Catalyst drivers will not work particular since Cat 10.5. The most suggested fix found on the Net is to replace the file atioglxx.dll with a version from Cat 10.4 or earlier. This atioglxx.dll is in XP & VISTA in ' Windows System32 ' In Windows 7 its in 'Windows SysWOW64' Its the same for 32 & 64 bit versions.

Jedi Academy SP has Stopped. Application Timestamp: 3f999a27 Fault Module Name: atioglxx.dll Fault Module Version. Discussions Rules and Guidelines.

Or to install a pre 10.5 version of the Cat Drivers.(hardly satisfactory) I've been using this method OK until recently when I found the latest Catalyst 10.12 still wouldn't work in XP with an older atioglxx.dll & not well in Win 7. Much further Net searching yielded the following fix: The problem occurs at the start up of these games which can not cope with modern complexities in the ATI OpenGl driver.

By going into the games Folder & making a copy of the main EXE file then renaming that to QUAKE3.EXE that should now run OK. The quake3.exe name fools the drivers into using a configuration the engine can work with. The using old 'atioglxx.dll' tactic is now not needed. Indeed the lastest version will give better results.

What 'modern complexities'? How inconvenient, when a comprehensive OpenGL driver fix on ATi's part would probably have been a 15 minute exercise by one of their driver team. ATi's GL support seems to be always late and half-baked. Nvidia latest driver 260.99 with a GTX460 on XP32 SP3 has no problem at all with the DOS/DOSBox/ GL games in my collection that I have had an opportunity to run with this newer nV hardware and driver (Star Wars JK 1/II/Outcast, Kingpin, SOF1, Sin Episodes:Emergence, etc, etc.). I have stayed with nV hardware due to the generally excellent Dx/OpenGL HW and SW backward compatibility in their graphics drivers.

I have a large collection of 'classic' PC games that I like to revisit from time to time and play on my current gaming machine. Russian Roulette with graphics driver changes, or having to find manual hacks just to play an older game are not my kind of fun. Sample Of Welcome For Church Program.
