Adobe’s next Lightroom Classic CC update will bring massive performance gains

Adobe’s next Lightroom Classic CC update will bring massive performance gains

According to a report by DPReview, a major update to Lightroom Classic CC is coming soon, and it brings major performance updates that should bring improvements for anyone using a multi-core machine with at least 12GB of RAM.

In Adobe’s own words:

In this upcoming Lightroom Classic CC 7.2 release, we were able to make significant strides with our partners at Intel on addressing key performance issues. We have optimized CPU and memory usage so that performance will scale better across multiple cores on computers with at least 12 GB of RAM.

 This means you should see faster import and preview generation, faster walking of images in Loupe View, faster rendering of adjustments in Develop mode, faster batch merge operations of HDR/Panoramic images, and faster export times.

Adobe Export Test

Adobe tested the new build on three machines:

  1. A 10-core iMac Pro with 32GB of 2666MHz DDR4 RAM, a 3GHz Intel Xeon W processor, AMD Radeon Pro Vega 64 graphics card with 16GB of RAM.
  2. An 8-core Windows 10 PC with 64GB of 2400MHz DDR4 RAM, a 3.2GHz Intel Xeon E5-1660 processor, and an Nvidia GeForce GTX 1080 graphics card with 8GB of RAM.
  3. A 10-core Windows 10 PC with 64GB of 2400MHz DDR4 RAM, a 2.9GHz Intel Core i9 7960X processor, and an Nvidia Quodro P2000 graphics card

All of the tests showed significant speed improvements when exporting 100 heavily edited RAW files as either full-resolution JPEGs or full-resolution DNGs:

  • The 10-core iMac Pro exported JPEGs 29.5% faster and DNGs 43.7% faster
  • The 8-core Windows 10 PC exported JPEGs 32.5% faster and DNGs 32.4% faster
  • The 10-core Windows 10 PC exported JPEGs 48.3% faster and DNGs 64.7% faster

DPReview also reports that while repeated testing with version 7.1 would see it slow down on Windows, that no longer occurs on version 7.2, so it seems Lightroom Classic CC will no longer slow down if you put it through a long editing session on a Windows machine.

Import speeds are also meant to see an increase, and DPReview reports that Adobe claims that they are “far from done”, and that there will be continued performance optimizations and improvements in future releases of Lightroom Classic CC.
