The issue of training efficiency

[Leven-Cheung]

Hi, thanks for your great work, I would like to ask how to improve the training efficiency? My device is 5090 but it cost me nearly 2h to render a 400 frames video while it only used 3gb vram to train.

I second this. On a L40S it takes >1h30m to process 300 images
