Why SDS loss

[VLadImirluren]

Although SDS loss has achieved good results, the recently published paper ProlificDreamer has improved SDS loss and achieved more powerful results. What is the reason that you chose SDS loss instead of adding vsd loss? Thanks

VSD loss is several times slower because it need to optimize a lora during NeRF optimization. Therefore we choose to use SDS for our current experiments.
