Late '15 iMac 5k fan noise with Adobe LR CC

Great video and I actually did hear people mentioning this last year when Yosemite came out and people had the retina iMac.

I guess we did it right then by buying the i7 so at least Lightroom can use that extra power compared to the i5.

I will test it as well when I get mine around mid November.

Does the picture load instantly when you zoom in or is there a delay there as well? That along with the sliders are what I care the most of course with colors loading as well. LoL

Here's a video I did demonstrating how LR is faster with the GPU off. This has been my experience with ALL four of the macs my company owns...

I see the same behavior on my 2015 iMac 27. However it is only in the Develop module; I don't see it when switching photos in the Library module.

Just because Adobe says LR "uses the GPU" we don't know for what. With Photoshop the GPU acceleration is limited to selected functions like scrubby zoom, Smart Sharpen, Liquify and Warp. Has Adobe ever stated exactly what LR functions use the GPU?

This can't be right.

Apple makes the best products in the universe and there's just no way their sacrifice on cooling & component decisions in pursuit of ultimate "Ive Sex Drool" desktop thinness could be a poor choice.

The GPU is only active in the develop module.
