what is the best software for my lenovo flex 2 with R4 and hd 8500M graphics?

I have a Lenovo flex 2 with A6-6310 APU with AMD R4 graphics, 4 gig ram and another 2 gig HD 8500M graphics card.

I installed radeon graphics version 17.7.2 which instantly slowed down my computer and would not even present an option to switch graphics cards so that I can use the more powerfulone for gaming.

so I uninstalled it and instantly my pc returned to normal speed and that gave me te feeling that even though the official AMD site ha recommended this software, it was not exactly compatible with my pc. I feel like an older version of Radeon might do the trick or I will be the saddest person knowing the reason wy I bought this laptop (graphics card) will never be be put to use... wen I run games they show that I only have 500mb of dedicated memory which is basically my R4 graphics.........please help its been almost a month already
