I have an ASUS UX31A which has 3317U and HD 4000 as graphic processor. I am using Windows 7 with lates drivers from Asus, only chipset driver is installed using Intel Auto Updater.
In Power options, i have set graphics for performance, checked it in Intel graphic options. But when i am running on battery power, graphic performance becomes awful, its quite enough when i plug the power in.
Is this a known issue? Any idea welcomes.
My best recommendation is to install the latest graphics driver from our side. You can get it at the following link:
A bios update using the bios provided by the computer manufacturer can also help on this situation since Bios updates are created to fix known issues.
