DXO OpticsPro 11.3.1 build 59 // MBP 16GB OSX 10.10.5 Yosemite
Just upgraded yesterday and already it has crashed twice. In each case, the circumstances leading up to the crash were neither obvious nor apparent, but in both cases, I had gone off to do something else, and tried to come back to DxO, and there was no response, before it finally threw up a Mac crash report.
There was a released version some time back that had crashing issues, which IIRC was attempting to see something in full screen.
This performance and track record is not encouraging. I've become accustomed to a DxO workflow and now know enough to select exactly what I want in the raw post-production adjustments. I really do not want to go learn a new platform (and trash all of my .dop files), but given the lethargic performance, I might have to do just that.
