The problem with multiple GPU is not stability. The problem is getting it to work in the first place.
With the GTX980 or 1080 and NVS810 in particular, the problem is that the computer won't recognise the GTX when both are installed. Nvidia considers using these two cards together 'undefined behaviour'. So even Nvidia's own Control Panel won't show it as an available GPU. It will just show the NVS810. The result is that Resolume will start using the NVS810 as its main renderer, which does not pack enough punch to run 8 HD outputs.
The only way to make this work, is to first disable all the NVS810 outputs via Windows Display manager. Then the GTX becomes available, and you can start Resolume with the GTX as the main renderer. Then you can re-enable the outputs again via Display manager, and have all 8 outputs of the NVS810 available, plus the outputs of the GTX.
We haven't done any real performance tests, because we don't really recommend this setup. It seems to run okay enough, but it's just too much hassle to get it to work. Every time you want to start Resolume, you will have to go through this whole process of disabling and re-enabling. I don't wish it upon my worst enemies to have to do this during the stress of a mid show power failure.
Joris, old thread but hard to find answers so hope you might be able considering this old comment.
I'm using res7 as a media server.
X299 10980xe with rtx a5000, a have 24 sdi bi-dir but need more syncable outputs. (Datapath is already considered. This would be more cost, as it would require 2 units to give 8 more outputs. And even then an other gpu would be needed as 4 outs are in use from the rtx a.
Considering your old answer, is this above mentioned process still needed?
I was considering to add a nvs810 with rtx a (quadro card), would this not work out of the box using my rtx a as main/active gpu?
