ABSTRACT:
Software for dynamically previewing changes to hardware driver settings for a graphics adapter is disclosed. Changes to the driver settings are dynamically previewed by forcing an executable graphics program module to load hardware parameter settings as changed, and drawing a region reflecting the changes using the executable graphics program library. The graphics program module may be forced to load new settings as a result of being newly instantiated. Conveniently, a preview region reflecting changes may be drawn in place of an already existing preview region.
