GTX 760 is properly shown but doesn't get full acceleration

Hi!

Recently built, most stuff in my hackintosh is working fine. Except the video... you see: my EVGA GTX 760 is shown with it's right specifications everywhere in the system (Mavericks 10.9.3) and it seems to be working fine. However, it isn't. I can perfectly see in Launchpad how it is not working with it's full capacity, or not even half of its capacity. The fades are weird, games like Outlast run in 5 or 10 fps, iPhoto bugs all the time, Chimera doesn't show in Full HD.

What do i do?!

Thank you.

CPU: Intel Core i7 4770K
RAM: 16GB Corsair Vengeance 1600mhz (using only one stick of 8GB)
MB: Gigabyte GA-Z87-D3HP
SSD: Samsung 840 EVO 250GB
VIDEO: NVidia GTX 760 - EVGA
PSU: Corsair RM 650

You could try changing your System Definition to iMac13,1

Good Luck
