glCompressedTexImage2D with PBO

Hi,

Does anyone here have ever use glCompressedTexImage2D with PBO ?!?!

If yes, how are the performances compared to glCompressedTexImage2D without PBO?

thanks,

J-P

I have used PBO with glCompressedTexImage2D on nvidia cards for real-time DXT compression on the gpu and had no problems, performance seemed good. Haven’t tried comparing it to without PBO.

If I read between the lines and don’t take you literally, the answer is “yes, and better”. However, you’re unlike to use that API with PBOs if you’re really trying to solve a performance problem.

Yes with the tip you gave me in the other thread for compressed textures, the performance are better with PBO.
