- Go to Lightroom > Preferences.
- Also please Go to the Preferences > Performance Tab, and uncheck "Use Graphics Processor "
- Restart Lightroom and see if it works.
Please follow the above steps if you are working on the latest version of Lightroom, if not please let me know the version of Lightroom that you are working on ?
Thank you Tanuj! Unfortunately, this didn't work. It will work for a few moments and then it starts going slow and eventually freezing. I have lightroom version CC 2015.2.1 My sliders and tools work but only in the small preview window, not the large photo in Develop mode.
Thank you a million times, Tanuj!
You are Welcome, Glad to help.
