speed of glPrint

I’m using “glPrint(‘some text’);” to write some words on the screen, but the words makes flicker.

the render speed is about 30fps, and the scence is very fluency when Writing noting.

should I put them somewhere else?

I am not aware of a function with that name in OpenGL. Which library do you use for text manipulation?

It’s a function used in a few of the NeHe lessons and not actually an openGL function.
You could try one of the other two methods described in other lessons.
