Are you using lots of edit fields to display text? I found FB3 no better than FBII at this, probably because Apple's Toolbox calls are still 680x0 emulations. Somebody please correct me if I am wrong. Perhaps you can speed things up by not using textedit for simply displaying text. Use quickdraw commands instead. Use functions such as STRINGWITH to justify text. I also don't use PRINT if speed is paramount. Quickdraw commands DRAWSTRING and DRAWTEXT are faster. Hope this helps ...
