Why on 1080p image with 13,000,000 gsplats, no speed up?

Hi, nice to have such a great work! But I met some problems when I was running the codes
When I render the training views of a scene with more than 13M. There almost no difference between FlashGS and vanillna 3DGS. Is it reasonable? I assume at least prune tiles could helps. But it seems almost same. Do I run wrongly or something?

This workload may have a long tail, that is, a tile contains too many small Gaussians. Pruning doesn't help it.

Thank you for you reply! Have you tested flashgs on large model? Is it the similar conclusion that it doesn't speed up a lot on large model? Since I just wanna make sure that I made no mistakes when I was running flashgs.

Do you know how to replace the code in original 3DGS?
