ultra slow performance Nvidia Gt620 2gb, help please

Recommended Posts

Hi guys, after try and try and try so many times to get Yosemite installed I found that Yosemite is ultra slow, so many graphics glitches, this are my specs:

MOBO : Gigabyte GA-970a-ud3 rev3

8gb Ram

Amd FX8350 processor

Nvidia Gt620 evga 2gb

D-link Dwa-132 USB wireless adapter

So in about this mac I can see the 2gb available of VRam but sstil it's super slow and glitchy also my Wi-Fi USB adapter doesn't work

Bootflags: npci=0x3000 PCIRootUID=0 GraphicsEnabler=Yes -v

I really appreciate any help.

UPDATE!!!!!!

Ok so the slow issue was because I was using Vesa drivers because I backed up graphics kexts so I installed the kexts again and when starting in the Grey screen when we can move the mouse it feels good and fast but before to login screen I got this:

Nvda: MMU ERROR: fault_pde at 0x0

I am not sure this is like what happened to me, but it seems like you have to fix your graphic card with a kext.

I have an amd sapphire vapor-x r9 290 and I had to install 2 modified kexts, then rebooted with PCIRootUID=1 and kext-dev-mode=1 boot flags to fix graphics and now the speed of the entire system is normal(fast). Before ding this it was so slow that I couldn't almost use Multibeast.

Look for something on Google
