I'm running Toshiba Satellite C55D-A, with AMD A6-5200, 4 GB RAM, and AMD Radeon HD 8400 VGA. I am having issues, the dxdiag said that my VGA have 2GB of graphic memory right ? yet games like skyrim is still looks a bit "slowed down" (not what i would describe as laggy though) its not as smooth as my friend's laptop with the same amount of graphic memory, in case of DOTA 2 it even crashes at some point when i play, the screen freezes but the sound is still playing and the game goes on, but i can't do things, and its not even a heavy game, and i play it in the lowest settings. can someone give me some help here
