GPU Mercury Playback Engine (metal)

Salut,

Dans la dernière MAJ Adobe premiere pro, il y a une nouvelle option dans le réglage du projet :GPU Mercury Playback Engine (metal)
C'est en rapport avec le dernier système mac El Capitan ?
Il est préférable d'utiliser OpenCL ou Metal ?

Une réponse du Forum Adobe que l'on peut approfondir en attendant un conseiller ici....

" Well I have some preliminary results of it. It looks as if using OpenCL is still better.

I've been using one of the trash can Mac Pro's (Model Identifier: MacPro6,1) with 2GB of graphics memory, 16GB of RAM, and a 6-Core Intel Xeon E5 at 3.5GhZ clock speed and for one hour of final product video, it took Encoder ten hours to export it using Metal. OpenCL would have done that way faster. Also, I noted that if I set my project settings to use Metal over OpenCL, then I notice that it requires me to render more often (Red Line) than if I'm using OpenCL which normally doesn't require me to render hardly at all (Yellow Line).

So in conclusion, I feel that OpenCL is still the render engine of choice for me. I hope this is useful and helpful to you all!
