I have a Lenovo laptop with AMD A8 6410 APU with an AMD M230 and a AMD HD 8500M, 8GB ram. The laptop runs games like Gta V and BattleField 3 but when I try to play low requirements games like Gta sa and Crossfire it runs them at a low framerate. I set the radeon software and they're supposed to be run with the good graphic card but and high fps but they run at 15-25 fps which is low for those games.
How can I run them at the actual potencial of my laptop, or how can I disable the bad graphic card and which one is the bad one?
