Memory Usage Optimizations for GPU rendering

[diego6S3FN]

Hello,  I'm just starting to use the GPU for Arnold, I got a RTX 3090 with 24 GB Ram but when I open some projects with a lot of textures and models it gets stuck because of the Ram consumption.

Could someone tell me where to get information on how to optimise projects for GPU? I've always used 64 GB on CPU and I don't care much about this.
Thanks in advance

Are you using .tx files for your textures?

If you can't render on GPU, one thing you can do is render on CPU (with AA=2 so it doesn't take too long) and enable info level log messages, and then look at the memory stats printed out at the end of the render. That will help guide you on what you need to optimize to get memory usage down enough that it will then fit on the GPU.
