Instead, you might want to use a mode such as 1440×1080 (if your display supports it) or 1024×768. One of the best memories from my Star Wars gaming holocron is loading up a LAN multiplayer match in Jedi Knight 2 with a low-gravity mutation switched on and a lightsabers-only weapon restriction. I'm trying to get JK:A to play in a widescreen resolution, e.g. I mean, okay, you can do it on widescreen resolution, but it's not as effective. Download jk2mv and u can play this game wit high grafic and widescreen.
Perhaps looking in another topic where the topic title is saying 'Game not working' at all might be a good start.
