Updated drivers, and that fixed it.

So my friend has been having some really strange glitches, with what as far as i can tell the smoke textures are glitching out and displaying patterns and solid colors whenever theres damage or explosions.

Is there anyone who has a clue how to fix this? Reinstalling and validating files didnt work, i tried it for myself.

Her graphics card is a Radeon HD 4850, 8gig RAM, and a Q3800 quad core intel 2 processor

Arrows, scorpions chain, green lanterns missiles, and batman's baterangs all cause the effect. Anything that explodes also causes it, like environment interactions.

This is for the steam version of the game
