I recently purchased my new notebook (Lenovo Y570) which comes with OPTIMUS integrated Intel graphic card coupled by GeForce GT 555M 1GB. I tried to play some games; however for some reason in game options show, that my Intel HD card is being used as a default graphic card. This suggests that OPTIMUS technology is not switching the graphic card properly.
Below are the things i have tried but the card still will not be used.
Change nVidia Control Panel settings in windows by setting the option to use "High performance Nvidia"
Updated nVidia graphic card latest version published on nvidia website (version 275.33) but has error message during installation. It always showed the error message that there is no compatible Nvidia hardware has been found.
I see on Nvidia website this is a common problems with many notebooks on the market using this Optimus Technology. Apparently there is also no way to supress the onboard Intel grahpic card as well.
Does Lenovo offer any sollution to this?
Please make sure you have done these prior to using Optimis card successfully.
Ensure the physical switch of discrete graphic card is enabled. Check out this article on how and where to enable the switch. Note: If you don't do this, the computer will show the Optimus Card 555M as being installed, but it will only use the HD 3000 graphic on the CPU.
