See this lengthy post concerning AMD driver issues with LR 6/CC: OpenGL Failure in Lightroom CC
Even users with high-end AMD GPUs are having performance issues. You can try updating the graphics drivers, which seems to help some users. On my i7-860 quad-core, Nvidia Quadro 600, Windows 7 system the performance is actually quite good with GPU disabled. I'm using a 2560 x 1440 monitor and would expect lower performance when using a 3840 x 2160 4K display (3.7Mp vs 8.3Mp).
Try disabling GPU support and see if it improves performance.
hi trshaner - many thanks for taking the time to respond. I had already updated graphics drivers but I will try disabling the GPU and see if that helps. Everything works fine on 2560x1440 monitor so maybe i just need to work something out re workflow where i use that monitor for intensive editing and the 4k monitor for low level work. 4K is so much better aesthetically - such a disappointment that the technology and software are not up to the task yet ..
To make the Develop module more responsive drag the side panel and filmstrip edges towards the center of the screen to make the Loupe preview smaller. In other words maximize these three panels, which will minimize the Loupe area.
Thanks trshaner - great suggestion. I turned off graphics card and that has stopped the focus/defocus issue which is a big help - thanks ! have also taken your advice re reducing loupe view. Will keep my eye out for graphics card driver and lightroom updates in hope that performance might be improved down the line. Many thanks for all your help:)
