Sure, the more complicated a plan gets, the slower it will become.
Also the Trace & Reference being turned on can affect speed.
But you really shouldn't notice a big lowering of performance.
It is basically troubleshooting to try to find the problem.
That is why I suggested to turn off layers or try another file.
If it suddenly goes slow when you turn dimension layer on then that is where I would start looking for a problem.
What it could be I have no idea - something the dimensions are associating to?
That is when you should get in touch with your local Archicad Support if you have a Select Service or Forward subscription.
Also have a look at this post which has a solution.
Although there should be no need to change this to a simple setting.
To me there is something else causing the issue.
Video driver update maybe?
