Hi, i have installed Zephyrot's 10.5.2 and Natit for my display, it shows me in the system profiler:

I would like to know what is Quartz Extreme and why is not supported? I have a MSI GeForce 7100gs 256MB TC
Athlon 64 x2 AM2 3600+
MSI K9N Neo F

Thanks!

Remove NATIT and try NVInject. You card 7100GS must support Core Image Hardware/Accelerated and Quartz Extreme.
Quartz Extreme accelerates the GUI to give animation, transparency, etc
