Hello everyone.... I have bought a Lenovo G 50-45 (80E300FSIN) laptop a few days ago. I have got myself GTA 5 too. The laptop has a 1GB of integrated (hd 8500) and a 2GB of dedicated(ATI JET LE R5 M230). Now, the problem is that in the game settings i can see that only 1GB of my Vram is being consumed. As a result the graphics are pretty shitty and the games lags like hell. I tried to google on how to switch between integrated and dedicated graphics. But being a computer noob I couldn't understand anything. They all said that going to the AMD Catalyst control and choosing high performance makes it switch to dedicated . But there's no change in the value. So I am missing my holidays cause i love the GTA seies. please help me out. Thanks in advance.....
