Hi Dan,
If i set check the Metal checkbox and set the retina rendering to High Quality, the app will significantly slow down, beyond the point of usability...
However i did try to play around with the settings to see what will be the optimal choice. So here it is:
View Quality - Bilinear
Display - OpenGL/Metal (both perform relatively the same)
Retina Rendering - High Quality (for the sharpening view)
Hardware Acceleration - unchecked (when checked, it will lag severely)
I did also try to switch the Raw Engine from Serif (default) to Apple. But both perform almost identical.
Well at this point Developing the Image is not that big of a hassle. Don't get me wrong, it still has lag.
BTW, do you guys are rocking AP on Desktops or laptops as well ? Could you please share your experience with the app performance?
Much appreciate the help!
