Imported line text is blocky, prints fine though - display issue?

In my attempts to create cured text, I produced the text in a 3D CAD programme then exported as 2D DWG. Opened in DS, but text is very blocky and angular. When you click on a line it shows a blue path that looks like the font SHOULD look like, but the actual white lines are not correct.

Is this a problem with DS, or my display?

When I print the "blocky" text out, the print out is fine, in the correct font.

Any ideas? Thanks.
