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.
That's actually making sense. the GT820M is a VERY weak GPU with 14.4GB/s of memory bandwidth, even a dual-channel DDR3 @1600MHz has 25.6GB/s.
I bet that by taking the resolution down the GT820M will still outpreform the HD 4400 by 40-50%. it's just not built for high resolutions.
