nDisplay, multi-node, multi GPU setup

Hi Everyone,

We have a LED wall that is currently running off 2 rendernodes, each containing 2 x RTX A6000s. The wall is split into quarters and each node is responsible for half the wall.

We have recently been running the wall with mosaic just fine


and using the VIVE Mars tracking system but found there were a few latency issues. To resolve this we thought to try nDisplay without a mosaic setup to see if that would improve things.

When we remove our mosaic setup nDisplay only seems to render to the top quarters of our wall and the bottom two quarters don’t show do anything at all.

I know this is a quick run down of our setup but would anyone here know what might likely be the culprit for each rendernode only rendering to one of it’s designated viewports?

I have tried playing with various GPU index settings but no success in getting the rendernodes to render their bottom quarters.

Any help would be greatly appreciated.
