I've uncheck the box and restarted Lightroom however that didn't work unfortunately.
I changed it to 20gb, I restarted Lightroom however that unfortunately didn't work.
You need to Optimize the Lightroom Performance and see if that helps.
Also, if you can try and create new catalog just for testing purpose. Import few images and use the Tone curve and check the response.
When I use the Tone Curve Adjustment tool in Lightroom, the curve won’t follow my Wacom pen. It’s response is slow, not smooth and most of the time if prefers to move left instead of upwards. This issue is making it very difficult to make small adjustments. I've tried using a mouse and I still have the same problem. Has anyone else had the same problem and solved it? Adobe, can you help?
If the mouse you are referring to is the Wacom mouse it sounds like an issue with the Wacom driver. Please update your Wacom driver to the latest version for your specific model here:
If using a Windows system select 'Use Windows Ink' as shown below in the Wacom Tablet Properties. This is not available on Mac OS X systems.
I used a colleagues mouse and the mouse worked perfectly on the Tone Curve so it seems to be a Wacom issue. I own a Wacom Bamboo.
I updated the Wacom drivers and there was certainly an improvement but it's not 100% fixed. The improvement is good enough for me to work with so thank you very much for your help.
I appreciate you help and time on this gentlemen.
Try the Wacom Tablet Preferences File Utility. First click on 'Backup' and save the file to a folder location or desktop. Next click on 'Remove,' which will restore the default settings. If it does not improve the tablet behavior use the 'Restore' button and select the backup file with your previous settings.
