I'm working with 4K footage in Premiere CC 2017. Working with effects and color correction is extremely slow. Using Lumetri CC panel is the worst offender, it takes 30+ seconds for an effect adjustment to show up on screen making it pretty much useless for subtle correction - if you blink at the wrong time you might not even see the change. I utilized past forum suggestions to speed up the work, but they're mostly older posts, and I didn't see any results when I tried the suggestions so I shelled out to upgrade my graphics card hoping that would fix the problem. It has made only a slight difference. Any recommendations on what is working for others would be appreciated.
