display quality poor

I'm running DraftSight version V1R3.1 x64 on a Dell Precision 64 bit workstation with AMD FirePro M5950 graphics. It works great for SolidWorks, AutoCAD, etc.

The text and dimension appearance on the monitor in DraftSight is very poor compared to the exact same document view in AutoCAD 2004.

The screenshots are Capture1: AutoCAD; Capture2: Draftsight (the difference is much more dramatice on screen).

What can be done?

Thanks.
