    Hi Unity team,

    Can somebody tell me if NVLINK on two a6000 GPUs is supported inside Unity? By supported I mean:
    1. Will Unity see the pooled 96gb of GPU Memory?
    2. Does this increase the raytracing performance in HDRP by pooling the resources of each card
    3. How about DLSS - will this be affected by the pooled resources on the cards?
    4. Will pathtracing take advantage of the two cards linked?
    Are there any specific settings that need to be enabled inside the HDRP asset settings to enable any features?

    Thanks

    OK - so I have set this up and but when I run out of memory on the first card the second one does not start filling up the memory - so can somebody tell me if this is expected behaviour?
