I have just switched from a PC to a Macbook Pro 15.
I never experienced any issues on my PC in the last 2 years of work, but since I started to work on the Macbook I noticed that the my mouse/trackpad movements were being delayed (feeling sluggish) when I had rulers on. I later noticed that this issue is present throughout Photoshop and InDesign as well.

I tried community recommended fixes such as turning off dictation and disabling "Scale Cursor Proportionally", and none of it has worked.

While I can have smooth mouse movements with rulers off, scrolling/navigating through the canvas is ALWAYS literally laggy; looks as if frames per second drop to around 15.

It's really frustrating experiencing such issues on a more powerful device than what I previously had. Please help.
