for posterity...
there is a hidden config option, USE AT OWN RISK, I'm on Creo 2.0 M100 :
text_height_factor
you can enter a percentage value, when I added the config it auto-populated with a value of 70, assuming that's default) I changed mine to 90 (smaller display size) and it is much better.
edit: Creo does seem a little slower on startup, noticeable but not that bad. Why this isn't an available setting out of the box is puzzling.
