Hi, Problem solved.
The culprit was IDLEHALT=1 in fdconfig.sys. After removing it, Desi-III refreshes the screen under FreeDOS very fast, apparently just as fast as under MS-DOS. Here's a summary of the refresh times under FreeDOS (for a given drawing I used for testing): With IDLEHALT=1 and FDAPM APMDOS 11 sec With IDLEHALT=1 5.5 sec Removing both 0.4 sec (estimate) Nothing else had to be changed in FDCONFIG.SYS and FDAUTO.BAT. Thanks, and a happy new year!
