I already get a warning from Autodesk XSI starting it every time and the menu texts and some numeric entry field, plus 3DSMAX's menus got distorted, overextended, because i'm using a bigger General Display DPI setting. :)
Bigger 'Add Event' and 'Parameters for' fonts in C2 would be a godsend.
The idea is, the eye uses much more fuel if it has to concentrate on small fonts all the time and people tire quicker, only they do not identify the cause.
Using bigger fonts, the eye has it easier, a developer can work longer hours without getting too bad red eyes.
