Screen lags with GA-Z97M-D3H

[Kenneett]

Hello,

I have installed Yosemite on my SSD and I can start my computer with "dart=0 PCIRootUID=1 nv_disable=1 GraphicsEnabler=No -v" The problem I am having is that the screen lags. The mouse stand still and will not move some times. When I logg inn and my desktop appears the picture flickers and white lines goes from the bottom to the top several times before the desktop appears. I have no idea why this happens.

I have been searching the forum for information and i found some links where people using my motherboard and CPU have made it work. http://www.tonymacx86.com/mavericks...-4790k-16gb-ram-intel-hd-graphics-4600-a.html
I tried to use the same MultiBeast setting as him but it did not work.

When I am using the -v and -v-x i get the message "Unknown CPU models 0x3c" And something about that my power supply is not identified and might can not be used. I have been in the BIOS and disabled vt-d.

I see at this post that he had to Update BIOS to F5, Turn VT-d off, Turn IGFX on and enabled, Set X.M.P. Memory Profile to Profile1 and Set USB stick to Boot Priority #1, SSD to priority #2 before installing Yosemite. Is things like this important before installing or can I do they after installation? He also installed Yosemite without the graphic card inserted. Is also this important? http://www.tonymacx86.com/yosemite-...-geforce-gtx-970-2-0-sc-yosemite-install.html

I am currently using:
Intel Core i7-4790KMSI GeForce
GTX 750Ti 2GB PhysX CUDA
Corsair Vengeance DDR3 1600MHz 8GB CL10
Corsair CX 750M, 750W PSU

Those white lines appear at login because of the nv_disable=1 flag, that disables any Nvidia kext and therefore any QE/CI. You have to use that tag because you need install the Nvidia web drivers. They are required to use a GTX 750/750ti or any other Maxwell based card. Once the drivers are installed remove the nv_disable=1 and add nvda_drv=1.
