I've recently got JK2 and I've had no problems in single player mode. After a while, I wanted to try out lightsaber battles against a bot, but when I run the game in multiplayer, the 2D screen overlays become corrupted upon entering the arena, and subsequently in the menus. In particular this effects the font so I can't read any text.
As far as I know, I'm running multiplayer mode with the same settings as single player (texture detail, resolution, etc), so I'm confused as to why this is only happening in multiplayer.
My system is P3 500Mhz, 128mb, Voodoo3.
