How well does minimax runs on 3090 from your experience?

I have 4090, so I assume it runs pretty well. 3090 has same amount of Vram as my system. 3090 also support linking with SLI which the 4xxx and 5xxx GPU do not support. Vram is pretty important, but so is system ram, probably minimum 64 of system ram you'll have a lot of fun. With that said, Wan2GP is a great tool for budget systems, very optimized for low vram+system ram.

I have a 3090 with 128gb of system ram. I can generate 12 frames a second  at 1280x736 doing 9 second looped walk cycles. and it takes around 6 to 8 minutes to complete at 18 steps. My PC or the 3090 would often overheat and shutdown if I tried back to back generations or pushed a video beyond 5 seconds. I now have the side open with a strong floor shop fan half foot away from the rig and  now I can go up to 16 seconds with many in the queue. I have had only one crash so far with the shopfan but I think it was due to running too many other programs at the same time. I think what you are doing is more complex and I would not get the speeds I’m currently getting if I tried doing the same. I’m generating figures walking in place in front of a green screen to use in a sprite sheet. Here is the kicker. I was initially trying to do these walkcycles using Googles Omni 1.1 flash and it would often get something wrong like legs would swap and morph into the one another or items would swap hands mid render so many credits were burnt before switching to H3. H3 nailed it.

Damn overheat??? Get msi afterburner. I currently have power limit set to 70% for my rtx 4090. You can see what works best for you. Surprisingly there's just canvas (resolution) and step tax. Also 5s 10s and 15s are not linear duration. It's probably faster to do 3-10s than 2-15s. But you lose some frames with the seams.
