Whenever i run a high demanding game (not a 2D) ,it looks like there are different refresh rates for different segments of the screen
(e.g the lower half of the screen is few ms ahead of the higher half).
It happens with both of the GPUs, and only in-game.
It doesn't happen in HD videos, and i couldn't even notice it in a "fraps" recording of the game (I have the latest GPU drivers).
Has anyone encountered this problem before, or has any idea how to fix it?

I forced VSync on Rage and Dead Island, and it works perfectly.
You have no idea how grateful I am, thank you very much!

My Acer ePower Management doesn't work. I tried reinstalling it through the Acer eRecovery Center, and downloading it from Acer's website, but nothing worked.
Do you guys have any idea how to solve this issue?

Well, I was wondering whether it has the option of setting a maximum charging percent for the battery. And if it doesn't, do you know of any other way/program to do that?

just right click, and choose nVidia - worked for me
