+1 "the AMD RADEON 6530D 512mb is an intergrated graphics chip". I assume that you have an AMD APU with built in graphics. It's not meant to be a graphics powerhouse for high end games such as BF3. That particular GPU would even struggle a bit with Diablo III.
I tried Diablo III and running maxed out. don't see any problem. but the issue with battlefield 3 is the shadows even on Low they are EXTREMELY strong and they eat loads of fps. Like in battlefield 2 i get 150 FPS but with shadows on its about 70 which is okay
