Ive got a HD4570 with 1 gb i set everythin to low and all options managed by application. But i get the receiving bug everytime when i play the large maps and getting near a big city. On smaller maps the bug doesnt appear ... ok less often but it is playable. What i noticed is that my ati card gets very hot above 100 degree. BUT and thats funny its only in arma if i play prototype or some other next gen games und HIGH details the graphiccard is under 70 degree. Even after hours of gaming ... don´t know why that happens. AN i cannot find any errors in the windows event log, and there should be one if the graphic card resets or something .. I love the game if it runs i can live with all the minor bugs but that bug is a killer ... only thing that works is if i get killed at the receiving screen it starts instantly over and i can respawn.. So what i do is i only drive with unarmored vehicles so that my teammates can kill me if necessary. Ehat btw is a very nice feeling. You shout to get killed u only hear the sound of the shot and see the respawn screen (doesnt work always!). But i cannot play any armored vehicles or planes or helicopters ... i mean i can but if i get the bug the team is fucked if i am the driver ....
