Editing and note selection lag in Cubase 12

Seems like my “in place editor” (editing CC data) is slower now after my change from Windows 10 to 11? Same lag is happening in the score editor, when I use the keyboard arrow keys to change the selected not, there is a pretty big lag.

Any thoughts?

Here’s a video of me editing CC data. You can’t hear the mouse clicks but I’m trying to quickly draw a pattern with 45 degree slopes up/down/up/down, but cubase is not responding to the click of the mouse, thus it’s missing parts of my intended ‘saw tooth’ pattern.

Other programs on my computer react lightning fast…

This REALLY slows down my process…

I should update this with further info…

This seems to be a graphics type of issue, because it is happening in several areas, when scroll from note to note, and try to move notes, editing CC data, in the Score and Key Editors, even when moving from track to track in the Console. All of which I do with the keyboard arrow keys. The problem is most pronounced editing cc data.

My GPU is updated and is set for high performance in my Windows settings.
