FCPX using dual Vendor GPU's?

[devon807]

Was editing a video in FCPX today, and realized that during export FCP was using my AMD and Nvidia GPU's. I ran several tests to see if it was maybe just using the Nvidia card for downsampling or just effects, but was used across the board even for native 4k->4k video exports. Can anyone else test this, It would be pretty cool to see FCPX taking advantage of two different GPU's

AFAIK, FCPX can utilise all available GPU (for compute only).
