mercury greyed out on gtx1080 cc2017

[ccced]

Mercury Playback is greyed out.

My rig is z840 2x Xeon

7 x nvidia gtx 1080

Latest Nvidia Drivers (381.65)

I can't understand why Premiere does not see it / use it.

Thanks

You have 7 videocards?

Moved to Hardware forum for expert advice.

[ccced]

Yes, I use GPU's for rendering (Octane).

1 1080 is in PCIe in motherboard, and the other 6 are in Cubix Xpanders.

However the fact that Mercury is not using even one of them is a bitter surprise.

Thanks for moving it to the correct forum.

Cheers

Run Adobe's GPUSniffer.exe in a CMD window and show us the results

As friend adviced me I got older Nvidia driver: 378.78

and now it's all working fine!

Crazy that newer drivers are not working well!

Thanks,

I would just temporarily disconnect your second monitor and see if that might be your problem, it has occured with s few setups.

[ccced]

Thanks Bill,

What I did now is to switch off one monitor and detach one Cubix so I have 5 x1080 working. It has solved the problem, I can use the GPU's in Premiere and the playback of 4k material is very smooth.

However this is a problem since I use this workstation for GPU rendering as well and needles to say every additional render node saves precious time.

I can see that GPU sniffer says that only 4 GPUs can be supported by premiere, but this is still 5 GPUs.

I tried earlier to install the latest NVIDIA drivers and that just caused my entire system to crash, and I had to restore Windows.

I know it's not a common setup, but it would be helpful to have someone from official Adobe support to intervene on this. I'm sure I'm not the only one with multi-gpu rig.

Thanks,

Ced

have you tried setting nvidia control panel premiere.exe as primary gfx app for just 4 cards?

Hey guys,

Just to let you know that Mercury works in CC Premiere 2018. It is flying with different layers of 4k and lumetri. Finally...

Thanks,
