iMac Pro + Premiere pro = laggy playback

[Nejc Slatner]

My Premiere pro on iMac pro doesn't want to play smoothly RED footage anymore, even if I put files on desktop SSD.
Even if I choose 1/8 of the quality it doesn't play any more.
It is mega choppy playback.

I don't know what happened, before it was playing smooth 5K on full resolution in Premiere.

Solved. If Video rendering is set to OpenCL it works smooth

What was it set to before?

Metal(2) = Apple

OpenCL = AMD

OpenGL = nVidia

CUDA = nVidia driver for MAC

Software = CPU rendering

That's the general rule of thumb.

I think it was OpenCL before. I noticed that all premiere settings had a reset.
