[LEFT][SIZE=12px][FONT=Verdana]well my friend bought a laptop it has on board graphics and also a additional nvidia graphics... now when I run game the on board [FONT=inherit][FONT=inherit][FONT=inherit]graphics [/FONT][FONT=inherit]card[/FONT][/FONT][/FONT] is getting detected and not the nvidia card.. I tried in bios but in the display part there are only 2 options 1 is optimus whic allows bot nvidia vga and intel vga to work and the other one allows only the intel vga to work... so is there a way to make games recognise nvidia or can I disable onboard graphics through device manager??

Hi , The option is the one where the nvidia card and intel on-board are shown, and the BIOS should select the nvidia card as priority if it can, and has a choice.
It's sometimes known as 'Primary Video' & the option is called PEG.
Make sure you save the settings when you exit or they won't be changed from before.
