I have an issues with slow response to tools in PhotoPaint, especially the erase tool...very "laggy."
I have Win 10 installed in a partition on my 5K iMac, so I wouldn't think this is a hardware issue.
Any suggestions on to remedy this?
Thanks in advance.
There is a known issue due to Windows 10 and the latest updates and AMD video. It is also worse if the Video memory is shared with main board memory.
