I had problems with the rotation tool - "OpenGL enabled document windows", so I looked on the community and found a way to fix it - turn on Graphics Processor, which I keep turning on and off when editing because there are some things that do not work without it being turned on and at other times I turn it off so there is not a constant lag.
So, I turned it on and went into Advanced and checked Anti Alias Guides, and 30 bit display. Now the lag is just extreme. I do a lot of complex editing on photographs and this is getting ridiculous. For close on a year now I avoid it because of all the lag problems.
Can anyone help? I have windows 10 and a year old gaming laptop, with extra RAM and a 1 TB ss drive.
