This guide made using Daz Studio 4.15, some information may be outdated if using a later version of Daz Studio. But there is no rule here, you can build your PC however your want, and as long as your PC can handle the power, cooling, and space requirements to add extra GPUs, you can use any combo of Iray supported GPUs you like if it works for you.This small guide will cover the Progressive Rendering sub menu within the Render Settings of Daz Studio.

I suggest a 12gb card as it would be the same size as your current 3060, meaning they would both be rendering most of the time. That is much, much, more preferable over trying to force an aging 1650 into action. If you can pop another 3060 in there, you would almost double your rendering speed. Your best option is to add another 3060 or 12gb sized GPU to your desktop. And this is assuming it is even possible to get this setup to work.

If by chance the 1650 could fit the VRAM, it is still so much slower that it barely impact rendering times. So if the scene is bigger than the 4gb a 1650 has, the 1650 will do nothing at all. When you use multiple GPUs, the scene must fit into each one's VRAM. Odds are very high that even if you could make this happen, the 1650 is too VRAM constricted to participate. The 3060 can run circles around around it, and has 3 times the VRAM. There is no point to trying to add a 1650 laptop to a 3060.
