thanks for the prompt response. :P I basically said that because adding ~5000 quads to the scene seems a bit wasteful for large bodies of text. I would think that games that require large amounts of text in game would see a performance hit when displaying a dialog box with individually textured quads. Granted that you'll rarely see all 5000 of those quads on screen at once, it's still a lot more polys than I feel comfortable adding to the pipeline especially when those polys could be put towards the environment or characters. Unfortunately, my app isn't at the stage where I can add thousands of quads and not worry about the speed hit. So, I'm just testing the waters to see if other options are available. E.
