Everytime I play dod....I see huge white squares whenever somebody shoots. It happens when I shoot as well. I am running with fog on, on open_gl. I have a GeForce4 TI 4200. What the hell can I do to stop those damn white squares!?

thats normal, its a bug because of the fog, theres white squares around the borders of all the sprites. it happened when 2.0 was first released as well. try going to a different fog mode (ie. if youre on cl_fog 1 go to cl_fog 2), and if that doesnt work, turn off fog altogether. mine does that sometimes too, its weird, one time i'll play and see the boxes, then i'll play again a while later without changing the fog settings, and the boxes won't be there. hope i helped.

I've heard that the minimap may have an effect on fog, try turning it off and see if that helps.

its cause the fog doesnt react with the particle system type cl_particlefx 0 if you want fog on, it will get rid of the muzzleflash though.
