Hi all:

I also am experiencing similar problems with Fonts and OpenGL. In
addition, I am starting to hear of similiar performance happening in
Vega/OpenGL apps also.

Currently I am porting an app that uses Performer with some direct IrisGL
calls to OpenGL (a non Vega app). We used to use the font manager in
conjunction with the direct IrisGL calls (fminit etc) that I understand
utilized raster fonts. With the OpenGL port, I am using now using X to set
the font and print the strings. The resultant performance hit virtually
kills the app. I am currently writing some simple code that will test
the use of the Performer fonts (pfFont, pfText, pfString etc) with my app.

My question is: Has anyone else experienced similiar problems when
porting to OpenGL? What have you done to get around the subsequent
performance hit? Any comments, stories, solutions, etc will be welcome.

Thanks in advance.
