As the title suggested, when opening some CAD drawings saved as PDF (not even heavy drawings), Acrobat just struggles enormously and this has gotten worse over the years, to the point where it's not even workable anymore. Opening, switching pages or zooming in takes a very long time.
I just downloaded Sumatra PDF, and I opened 20 CAD drawings in less than 2 seconds and the viewing experience is just on another level, it's blazing fast.
If the original developer of the PDF format doesn't know how to handle these basic PDFs whereas a free software does the job 1000x better and faster, there's clearly something wrong.
My workstation specs are quite ok: Threadripper 3990x, Nvidia RTX3080Ti and 265GB RAM so I don't think that's the problem.
