Probably these dual graphics don't work well because of the crappy driver. Try fix drivers optimized for APUs. (Simply type APU fix drivers for laptops or etc and google it). My friend has older gen APU (A6-3400M quad-core, definitely inferior than urs) and also dual graphics (6520G igp+6650M dedicated) and after installing SG fix driver (13.12 w/ revision 13.25) and tweaking his CPU to 2.6ghz he could even play Crysis 3 in Medium-High, with SMAA 2x, and could also run BF4 in medium-high, GTA IV in neally full settings w/ 4x AA...so on. AMD isn't that lame when u'r looking for a budget laptop, simply the DG drivers are ruined by laptop vendors.
