does anyone have the same problem with me and my ASUS N43SL? my lappie spec: Processor : Intel® Core™ i7-2630QM Processor (2.00 GHz, 6MB Cache) Memory : 4 GB DDR3 PC-8500 Max. Memory : 8 GB (2 DIMMs) Video Graphic : NVIDIA GeForce GT 540M 2 GB OPTIMUS & integrated VGA INTEL HD Display Size : 14" WXGA LED Hardisk : 640 GB Serial ATA 5400 RPM the spec seems good compare to the price (around US$ 800-850). But when i test with the applications which i usually used like AE, AI, PS, etc. my dedicated GPU (NVidia GT540M) didn't works (there's showed on NVidia GPU display) and it seems the applications running on integrated/INTEL GPU. I tried to update or downgrade the driver, and forced the application running on dedicated GPU ("manage 3D setting" and "set physX configuration" in NVidia control panel) but the problem still exist... does somebody know how to shut down this optimus "thing", so i can use just the dedicated NVidia GT540M in my lappie? or perhaps the notebooks that have similiar specs (without NVidia GPU and the optimus "thing" -> ATI maybe?) with similiar price? thx for your suggestions ^^Y
