Speeding up the scene transfer.

[eyepiz]

I find that one of the drawback of RT GPU is the scenes texture load time to the GPU. Is there any recommendations on what textures formats work best for GPU? seems like the textures are the taking the longest to load.

Would converting all my textures to jpeg or any other format speed things up? It's is my understanding textures expand on the GPU so I'm not sure if it would be any help.

So far using the re-size textures on the GPU slow the loading times down, as well as using the VrayHDRI loader it's seems to slow down the loading as well.

I would appreciate advise.

I'm using Titan X's for my GPU's

I don't think it depends on the texture format so much; we just need to keep the textures on the GPU and/or speed up the CPU part of that process.

Thanks for quick response! I think if we had the option to cache the textures on the GPU it would really help, maybe like the use cached assets in DR option or someting like that.

Some scenes just have hundred of textures and I guess we a also bottleneck by the PCI express bandwidth as well.

Do tiled formats like tiled EXR or .tx help at all? Or will the entire texture still be loaded at the start?

For the moment, everything is uploaded (we know that we have to fix that ).
