I don't get it. How can you render anything in 30 minutes? I use a single RTX 2070 on a decent gaming rig, and 3-12 hours would be minimum for anything worth looking at. Like certain hairstyles already cut the FPS in the viewport in half, adding environments reduces the FPS at least by another 75%. And it seems like the render time grows exponentially with the amount of light sources.
Or is it really so that the RTX series isn't properly supported by DAZ? Because during renders my CPU is always at 100%, and the GPU only shows very occasional activity. RAM is also more like 8 of 32GB in use. It's kinda frustrating when you have a GPU that cost more money than most people's entire rig.
