To repeat - this will cause JKA to crash every time on Multi Player - but it works great in single player I just reproduced it on a desktop (GeForce FX 5900 Ultra + 45.23 WHQL drivers):
This crash bug isn't isolated to notebooks : The Problem : JKA will crash under multi-player when started with a custom resolution r_mode -1 (in this case a widescreen resolution for widescreen gamers) On a personal note : JKA is AWESOME looking in a widescreen with a proper FOV. Posting here because this info might be useful for some players on widescreen computers who want to play JKA in a non-stretched out resolution in its full glory (this works fine in single player mode):
Most of the info in this post is available on line (and has been available on line for years now) given that JKA uses the same variables to control a widescreen output as Quake 3A This is my attempt to get a problem with widescreen and JKA fixed.
