Is anyone here using two RTX 3090's in NVLINK for Daz? 

How does it work?

Does Daz 4.20 detct the doubled GPU memory?

Windows 11?

I've never use 2 x 3090s, but I've used 2 x 2080Ti nvLinked, and the VRAM gets pooled 2 x 11Gb = 22 Gb.  I didn't get double the speed, mor like a 50% increase. But that was a few years back. The cards, because it's close proximity to each other, didn't get enough cooling, so I sold them both and got one RTX3090 instead.  The 3090 itself runs pretty hot, so I would suggest if you get a pair nVlinked, you have to liquid cool them

Memory is pooled for materials, not everything, and there is a speed penalty as a result of doing it. However, materials do tend to be the big memory hog.
