    LR6 Develop Module: is my GPU working correctly? Color "flash" and "Live Preview Rendering Time" feels long.

      Hi,

      I don't know why, but in the Develop Module in LR6, it feels like Live Previews are not on par with the speed I would have expected now with GPU acceleration.

       

      SEE THIS VIDEO SCREENGRAB: https://dl.dropboxusercontent.com/u/5840419/lightroom6performance.mp4

      In this preview, the images I am viewing all have been Standard Size Previews generated.

      Note: each photo is a Nikon D800 Raw, and manipulations have been done to it (as you can see in the video, many sliders have been used to grade the photo).

       

      See what happens:

      - I click on photo thumbnail

      - The Large preview appears, somewhat desaturated and "blurred".

      - then a "Flash of Color" appears (the proper color saturation appears)

      - then the image becomes sharp (in focus, as opposed to soft preview)

      Overall, a process of about 4 seconds each time.

      Is this normal?

       

      I do not understand why.

      And GPU Acceleration is enabled. GTX 670
