I am having a problem with Lightroom 2015.6 constantly hanging or crashing when I go from the library module to the develop module. I have a Windows 10 machine with a AMD Radeon HD 7450 graphics card and have had NO problems in the past. Nothing else has changed.
Lightroom will not let me disable the graphics card in the preferences tab so I disabled it in the device manager and it seems to work now. Does this mean that I will have to buy a new graphics card just to run Lightroom?
Please follow these instruction to manually disable GPU acceleration for LR: Adobe Lightroom GPU Troubleshooting and FAQ
If done, re-enable the GPU in the Device manager.
If you are not using a 4k monitor, there's no gain for you to have GPU acceleration - simply leave it off.
Thanks for the information .
