please be more specific with your problem. What game are you running? what fps are you getting? what detail settings are you using?
Make sure your actually using the Radeon graphics and not the intel graphics.
Radeon Settings -> Prefrences-->Radeon Additional Settings->Switchable Graphics Global Settings and put everything on maximize performance, and your ready to go. Your laptop is not the best but you can still play alot of great titles from this year and the last, next year u might want to buy a new laptop But at least u will save some money for now.
