Lightroom CC
Quick Develop
When I make any changes to a file (D800 NEF) in Quick Develop in Loupe view, I get a message "Loading" for about 4-6 seconds (forever) before the change is rendered. In LR 5.7, the same thing takes less than a second.
Fresh install of LR CC.
System Preferences reset to default, just to be sure.
"Use Graphics Processor" enabled (no difference when it is disabled)
MacBookPro 2014 fully loaded (i7,16GB,1TBssd) OSX 10.9.5
No other software running.
This makes "Quick Develop" largely unusable!
Please fix, ASAP.

The new GPU assisted speed in Develop module seems to be working fine, is appreciated, and is getting closer to how it should be.

I am pleased to report my slowness issue seems to be gone with the new release (2015.1.1). It is blazing fast. Thanks for the effort to fix it and keep improving both version CC and 6.

Today I ran Lr CC 2015 6.1.1 on a large project on my Win 8.1, i7 3.6 GHz, SSD, 32Gb, nvidia GeForce GTX 770 PC and the performance issues are still there. Checking "Use Graphics Processor" still results in the same clunky performance.

Working with a simple Radial Filter CPU usage was a solid 100% with "Use Graphics Processor" checked and around 35% with it unchecked. Export delivers a solid 100% CPU usage with or without "Use Graphics Processor" checked.
Serious work will still need to be done in the flawless performance king, Lr 5.7 (on the same tire-shredding machine).

It's been suggested that uninstalling/reinstalling Lr could be worth a try.
