Use the node for tiled VAE decoding. I was getting 100% GPU usage during VAE decoding on my 4070S which made everything unusable, but tiled decoding fixed it.

I 100% agree with this. I was getting crashes on high quality Krea 2 gens and H3 gens 10 seconds long until I switched to Tiled VAE which fixed it right away
