I went back to 5.3. Both 5.4 & 5.5 slowed it down, but nothing like 5.6 did. Everything worked well with 5.3 so if it ain't broke, don't fix it. I do have 12gb of ram.
When you consider that there are no new features, only bug fixes and new camera/lens support. It is very hard to think that LR5.6 would have any performance issues different from 5.5. The introduction of LrM with version 5.5 was a new feature and performance issues might have been expected (although I never experienced any).
Bug fixes require a new compile of the whole source code. Even though the code is modularized a whole new executable is built. So a bug fix to LrM module could ripple onto Develop, Library etc.hi
but the bugs fixed are related mostly to lightroom mobile<->lightroom desktop
didn't find only lightroom desktop bugs fixed,am i right?
cheers
I can offer a suggestion. Most often the folks with problems are Windows users. Windows app are notorious for running all sorts of background "helper" apps and almost every Windows user is forced to run some sort of Virus scanning app that checks every file that gets touched by other programs like LR. If my Windows system had problems with LR and others did not, the first thing I would do is disable all of the background tasks and services, especially the Virus Scanning apps only reintroducing them one by one unto the performance hit was experienced. Once I figured out which combination of tasks and services caused my system to creep, I would take steps to remove the offender(s) so that I could run LR.Jim, it would be great to finally figure out why it does happen that for some users what should be a straightforward update turns into a performance nightmare....but you're right, it seems to happen with every update.
All I can suggest to the OP is to try what I posted in this thread earlier today.
Which is why I suggested starting up in Safe Mode to see if Lightroom runs OK in that mode. If it does, then a bit of detective work is needed to find the conflict.
