I wanted to post a follow up on my notes on Lightroom CC/Lightroom 6 of a couple of weeks ago. In it, I noted some glitches and performance problems mostly with Smart Collections, especially when doing a lot of modifications or putting many of them in a sub-collection and working with them.
The nice people at Adobe reached out to me to discuss what I was seeing, and they recommended testing a couple of things. It took me until early this week to find time to do some significant testing, but I wanted to let people know that one of their suggestions — turn off the GPU acceleration — worked like a charm for me and Lightroom has been fast (noticeably faster than Lightroom 5) and rock solid since I turned it off. The other night I spent some time re-arranging a number of my folders of Smart Collections as part of a refactor of my collection and I’m convinced that would have triggered the bug if it was still hanging around, so I can say with confidence it was the GPU support that caused it.
This isn’t too surprising: that code is brand new, coding GPUs — which are built by multiple vendors and differ from computer model to computer model — can be a tricky thing. There have been reports around the web of other people seeing glitches with the GPU support. Turning it off solved it for me, and the performance without it is more than find for me, and I know Adobe will track down and eliminate these glitches.
I can therefore upgrade my view of Lightroom 6/Lightroom CC from “pretty good” to “really good, solid and fast” and it’s well worth trying out. If you’re running Lightroom 4 or earlier, you are making a big mistake by not upgrading because the features and performance updates can really streamline and improve your post processing and the time needed to work your images.
And thanks to Adobe for helping me debug this.
