Hello
I have brought a brand new Hp Pro book 450 g2 5th gen core i5. previously i installed windows 7 ultimate 64 bit. beacause of some compatibiity issues i had to install windows 8.1 64 bit. the problem is in the system resolution task bar the dedicated video memory is 0mb. previously in windows 7 it was 2500mb. why is it so i have installed all the drivers from the internet but the problem is still there. i have tried to run games like gta 5 and max payne 3. the gta5 after running for 5 mins give an error and the maxpayne is not working
Kindly guide me
