Dual GPU (RTX 4080 + 4060 Ti 16GB) for Daz 4.24 Iray

in Technical Help (nuts n bolts)

I do heavy animation rendering in Daz 4.24. Since the RTX 4090 is too expensive, I'm planning a mixed GPU setup: 1x RTX 4080 (16GB) + 1x RTX 4060 Ti (16GB).

This gives me a combined 14,080 CUDA cores. I know VRAM doesn't pool, and I strictly optimize my scenes to stay under 16GB. I cannot upgrade to Daz 6 or use the RTX 5000 series because my entire workflow relies on Daz 4.24 plugins.

My question: Will this dual setup work smoothly in Iray to speed up my animation renders? Are there any hidden bottlenecks I should be aware of?

    Iray scales fairly well, so yes you should see benefits - there are some overheads, though, so you won't get the absolute combination of the two cards' potential.

    Can you explain it exactly?
