My father bought me a Hp r007tx 2 months ago. When i saw the sticker of nvidia on the Laptop i was very happy thinking of playing games smoothly.But when i tried to play games like NFS hotpursuit and Most wanted. The 820M performed very weak. I tried with integrated intel hd4400 and the FPS were far more better than that of Nvidia. I searhed in youtube and the other peoples 820m performed very good.but mine sucks. I mean how can intel hd play games at greater frames than nvidia. Is it my laptops problem. For.eg. In youtube a guy with same specs as mine got 55 fps on NFS.....but i stick with 15 fps in Nvidia and 28 fps on Intel. Please Help.
