AI renders "Actual Size" not to actual size anymore.

[BreadAndButter]

Hello, my AI doesn't render the actual size anymore with "Actual Size", does someone have a clue why and how to solve that? The true size is here rather ~130%. With my current hardware and software and same AI once it _did_ render it right, but after a reinstall of AI, it doesn't anymore.

AI CC 2017 21.0.0

Windows 10, with UI scale beeing 100%

GTX 1650, with the card's drivers beeing perfectly installed and configured

Can you check out the "100%" option in Preferences > General?

Hi Mrs Gause, are you sure there is this option in AI CC 2017? I can't find it!

It's been introduced in a later version, sorry. Did you have a newer version installed previously?

Yes, IIRC that was a newer version. So with CC 2017 I have to live with that bug, I guess.

I solved it otherwise. I created a new artboard in size of DINA4, then I took a sheet of DINA4 paper and held it onto my screen and adjusted the zoom level until I had a ~perfect match of artboard and real paper. That was 128.8% for me. I created a new "view" with that value, so that I will have a shortcut to change to that zoom level whenever I need to.
