Nvidia RTX 3080 ti: 0.08 seconds per frame. Estimates to be done in about double the input time. (30 sec clip should take about 1 min.)
I hear the RTX 3060 does about like the RTX 2070 Imo mentioned. Maybe a little worse.
Maybe I have not used the Gaia HQ model on my other computer, but with Proteus and Artemis, it gets about 0.40 seconds per frame. It’s using a GTX 1060 3GB.
Edit: I got a chance between movies. It runs Gaia HQ at 1.25 seconds per frame. I feel like it shouldn’t be that much better than your 980.
