[SOLVED] Xonotic crashes upon joining server

Hard to help you without more informations about your computer (OS, GPU model, RAM, etc.).

My first guess is your machine isn't powerful enough to run the game with the selected settings. Locate the file config.cfg in your xonotic/data user directory, delete it or rename it, and run the game again. This time, in menu>settings>effect press low and apply. Try to load a map or a party, and only then enable more effects to improve the graphics.

Windows7 64bit.
i7 940 @ 2.93ghz
12gig ram
SLI radeon 6800s

Pretty sure I'm good on the Xonotic front. I'll try the suggestion but I've fully deleted the directory and reinstalled before.
