    Why is Lightroom So Painfully Slow?


      I would like to know why Lightroom is so slow on my computer when all my other programs, including Photoshop, run very quickly.


      It constantly hangs and freezes when doing simple things such as scrolling through my library (no matter how small the catalog is), and it's even worse when working in the develop module. Simple things like moving from photo to photo take ages and making adjustments lags a lot, especially when using local adjustments. The spot removal tool is one of the worst, the mouse jitters all over the place making it frustrating to use.


      I have no idea what could be causing this, I have tried disabling GPU acceleration, tried different catalog sizes, tried using a new user account on my computer, even overclocked my CPU and all this has done very little to improve performance. I've also tried using the catalog on my SSD and that also made no noticeable difference.


      Here are some details of my system taken from Lightroom:

      Lightroom version: CC 2015.7 [ 1090788 ]

      Renderer: AMD Radeon HD 7700 Series

      My CPU is an AMD FX 6300 (is it something to do with AMD over Intel, or could it be the GPU?)


      I've tried working with my catalog on the Mac computers at college and it is lightning fast in comparison, and those Macs are underpowered and are almost 7 years old!

      What am I missing here!!?
