Yesterday I updated Catalyst driver to 15.7.
Now my Lightroom is unusable.
When I open it in develop mode it shows photo, but when I go to library and back to develop - it stops responding.
I realized it may be related to Radeon driver, so next time I opened Edit->Preferences->Performance, but when I try to disable "use graphics processor" it stops responding again.
How to fix it?
How to disable graphics processor not from UI? Can I edit some setup file?
PS. Windows 7 64-bit, AMD Radeon R7 200
