GPU rendering - Metal vs CUDA


I am upgrading from a NVIDIA to a AMD GPU on Mac. I realize that some effects that I use a lot are not GPU accelerated on Metal, where the same effects were accelerated on CUDA. Examples: S_DefocusPrism and S_FreeLens.

Is that to be expected?
Is there a list of GPU accelerated effects?


Hi Annael,

Not all Sapphire effects are metal accelerated in Sapphire 2021. This is an ongoing area that we are working on, hoping to support all Sapphire effects with Metal acceleration for a future release. Here’s a link to the list of effects currently supported for metal: Boris FX | Sapphire 2021 Metal Performance
