Did you even try to turn off the GPU acceleration and see if the crashes go away? This would take you only a minute or so.
Lightroom should run properly when networked drives are not mounted.
No, not yet. Thats a good idea and an easy test.
Yup, this always worked on prior releases (i.e.: LR5, LR4, and LR3 all worked without every photo being accessible), but now if any photos in the collection are not accessible, LR crashes which is why I ventured down the catalog path.
I'll turn off GPU Acceleration to rule it out. Thanks for the suggestion.
Yeah, I saw that, but when I checked LR's system report, LR indicated the Open GL test passed.
Open GL support passed:
Graphics Processor Info: NVIDIA GeForce 9400M OpenGL Engine
Check OpenGL support: Passed
Also, just as an FYI, LR auto detected the graphics adapter and enabled the accelerator by default during the installation.
I now suspect the web link is correct and LR has a bug since I've disabled the graphic accelerator preference about an hour ago and LR hasn't crashed <insert crossed fingers here> yet.
I suppose, that is exactly why it is explicitly listed. It's detected and also fulfills the requirements and still does not work as expected.
Thanks everyone! I'm convinced that explicitly turning off the GPU acceleration was the solution, despite LR6 incorrectly detecting and enabling it during installing...translation: LR6 bug.
I've been putting LR6 through the paces for nearly 2 hours now and haven't experienced a single crash where before, it would crash with every second, or third photo procesed.
Thanks again for your help, I really appreciate everyone's quick and professional responses!
