System Requirements

Pre-populating the GPU cache 

The very first time you render with the GPU, the GPU renderer has to create a cache of shaders. This can delay the time to the first pixel for your first render.

To avoid the one-time delay, we recommend that you run Pre-Populate GPU Cache before you do any renders. Note that pre-populating the cache can take up to 15 minutes.

The cache only needs to be re-populated after installing a new Arnold version, updating to a new NVIDIA driver, or changing the hardware configuration of GPUs on the system.
