Performance Problems..

I use "Decklink HD Extreme 3D +"

I want to play animation using OpenGl.

but "glReadPixels" is too slow. So, I cant play animation.

When I use glReadPixels, performance is really slow and shows a lag.

Anyone, know how can solve this problem?

Hi,
It would really help if you posted your system spec's plus what graphics card you have.

Thanks Radman for your comment.

Hi,
Have you tested your system with a 3D utility to check your system performace outside the Decklink influence. Framerate etc.

How do you have your internal hard drives set up. What are you running your media on?
Are all your drivers up to date.
