Hi guys,

After fixing the not booting with the nvidia web drivers bug on my GTX 970 another problem showed up.

I have 2 monitors dell u2515H 1440p monitors one is connected via display port ( this one does not turn on ), and the other is connected to the dvi-d port using an dvi to hdmi converter since the resolustion on hdmi was not 1440p.

On boot the graphics are lagging like crazy and it's not workable, but after replugging the DP cable in my GPU everything turns to smooth as butter.

Was running the macpro 6,1 SMbios but tried the 5,1 but having KP's now, will reset that back to 6,1 to see if anything changes.

If anyone knows how to handle this issue or where to look for for better troubleshooting let me know :)

Specs are in my sig, running 10.11.5
 
Fixed it in the end by doing a fresh re-install of OSX running multibeast and using the macpro 3,1 smbios in combination with the nvidia web drivers.

OSX runs smooth as butter now :)
