OpenGL Flickering
« on: September 23, 2011, 12:27:31 pm »
I'm trying to make an electronics simulator kind of thing which needs to be quite fast to allow really bit simulations to run fast on it. When I draw something just once, and leave it there it flickers and I would really rather not go through all the pixels every frame as that would be rather slow being a pixel based thing so it would need to draw each one individually.

Thanks for any help :)
If a picture tells 1000 words, then a YouTube video clearly tells 1000000 making a YouTube video obviously a larger work than the Lord Of The Rings, or some other massive novel. Thus are the laws of YouTube videos.

There's no persistency, windows need to be refreshed continuously.

What do you mean refreshed? I'm doing App.Display(); every time...do I have to also redraw all the OpenGL stuff as well?

Yes, that's what I meant.
