Hi All,

I've been testing the latest KarmaXPU update on my M1 specced machine. Currently it doesn't look like XPU is utilising GPU cores on the M1 machines? is this correct?

When I go to render I still see Embree CPU 100%. Shouldn't this be 0% if GPU is being used?

XPU only supports Nvidia GPUs currently.

Ok I was confused switching between CPU and XPU. XPU seemed faster than CPU so I thought it was using GPU.

They're two different renderers. Karma CPU uses VEX-based shaders that are someone backwards compatible with Mantra. Karma XPU is a new renderer that only supports MaterialX based shaders and USD preview surface shaders and a few others that are specific to XPU. XPU uses CPU and GPU if available.
