My copy of the game keeps crashing after about 45-60 min. of play. I use the updated version of the game and have since startup. The game loses all text and there are blank black bars where the ammo and score HUD notifications should be. The game then makes all Character modles, furnature and walls invisible, although still playable (the cammera still follows my character and I can still kill enemies, use weapons, etc.). Then the entire map and all entities dissapear, only leaving the flashing background and music. I cannot change graphics cards as I am on a laptop. Specs: Toshiba 15.7', Intel i3-m @ 2.5 ghz, Intell graphics 4000, direct x 11, 600GB Hard Drive, and 6GB RAM running Windows 8. please help. The crash does not kill the game, but it is annoying. Any GENUINE help would be greatly appriciated. No spam comments and not helpful fixes like "Lol noob get a better computer XD" or [insert generic answer by a person who has no solution to the problem, but wants to sound smart]. Thanks.
