V-Ray Next optimised render setting?

Hi, I’m very new to gpu render, for my production render gpu, this is my render setting, basically just 0 out the max render time so it will render the allocated full max subdivs with noise threshold.

However, as I increase the gpu texture size to full size textures, the render time increase by a lot, sometimes we will use 8k, 16k texture.

Is there a way around it?

You can try the on-demand mip-mapping mode for textures, it’s quite efficient.
