I converted my application over from using TAO.SDL and the SDL TTF library for rendering fonts to using the OpenTK fonts.
The OpenTK fonts don't have the correct pixel precision and the look blurry. Also the bottom of the font is getting cut off.
Am I missing a setting? I did find that if I change the font size to 8.25 instead of 9.0 the bottom of the font does not get cut off.
OpenTK Version (Updated with fixes resulting from this thread)
