We purchased two Quadro P5000 video cards and set SLI mode in the OS Windows via Nvidia GUI. After this we launch the Siemens NX programme (3D build programme) and we see that the image is twitching. Such a feeling that there is a desync between video cards. There are times when everything is working fine. But more often, everything works badly.
These are new video cards were purchased from a shop

Use one monitor.
DP or DVI I tryed diffrent cables.
My observations:
When I set “Rendering mode SLI” in One Graph Processor that The problem with jerking the image has passed but this is not what we need.
So it seems like you are not using an SLI-certified motherboard and is not using a Quadro SLI bridge. Thus, we have not tested, nor do we officially support, the configuration you deployed—which is likely why the results are unpredictable.
However, the since you also seems to be using only one display, you can try using one GPU to try to isolate if it is providing the same behavior with just GPU…thus, likely something else, such as cable, monitor, etc.
