Now I have some problems with my laptop. Everything worked perfectly, but I don't know what happened with my graphic card even onboard and Nvidia.
When I play PES 2013, the setting dedicated 32MB from both intel HD graphic 5500 and Nvidia GT 830M, so I can enter this game even low setting. It's so bad.
I check display adapter in device manager, dxdiag, and GPU-z. they always show the appearance of two card. But the intel HD graphic 5500 is dedicated 0MB????
They were up to date in dell website and autochecked by themselves. I check on nvidia and intel website, they have new versions for them but can not install because they are not compatible with system.
Now I am not able to play any game with high configuration such as PES 2013 or FIFA 13 with this new laptop.
