Hey everyone.... How r u all??? Nice to meet u all..... ^_^

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 graphics card 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??

laptop model: lenovo ideapad z570
graphics card: Nvidia geforce gt 540m

and one more thing...In one of the game I checked PES 2012 it shows as its using onboard graphics.. and I tried arkham city and tried enabling hardware acceleration physx but it said the laptops hardware doesnt support it....

one more thing I just went to nvidia control panel and in there 3d settings and there global settings its written there preferred graphics processor is integrated graphics.. and I couldnt change it.....

can I disable the onboard graphics card in device manager???

thanks....

Just change prefered to nvidia.
It should help as long as the drivers are properly installed.
Sounds like they are.

couldnt change the preferred one.. its grayed out tat is locked.... and not only tat i have my game to use nvidia and tat too it chose automatically...but the games wont lauch says my graphics card doesnt support...

i searched around internet.. the problem seems to the optimus technology... which uses both on board and nvidia... and cuz of tat my game wont run... is there a way to turn off optimus technology???

Might try going the the nvidia site and installing the latest drivers.
If it is not letting you select it,it may not be properly installed.

syaoran7li, just exactly what "graphics card" are you using with the laptop? Brand, model number, connection method, etc. would all be useful.
