I've got the 1.17 release of Q3A, on a PMG4 400, 256MB RAM, Radeon, 9.0.4 and all latest updates.
When I run Q3A, everything is fine unless I set the texture detail to max. That's the setting where it has a slider with four positions. On the fourth position, when it loads the level, it freezes on the screen that shows all the icons for weapons, items, and bots. I reinstalled Q3A and same problem. I have 180MB RAM allocated to Q3A, and hunkmegs is set to 150MB.
Anyone else have this problem? Any suggestions?
