I was just trying to do this myself (for Jedi Outcast specifically). I used Topaz AI Gigapixel to increase the resolution of all the textures on the first single player map, Kejim Outpost. 2x original resolution worked perfect. However, 4x resolution causes the game to crash. HOWEVER it works fine if I compile the OpenJK version of JK2 and run that. The biggest textures x4'ed ended up being 4096x4096 so I tried halving those ones again just in case that was too big - but it didn't help. I also made sure they were saved in the baseline jpg format. The 4x textures look really nice! I just wish I could figure out why they seem to crash the game... (I have the ultimate weapons mod on in the 2x shot, but removing all other mods didn't seem to make a difference either)
