View Full Version : Fast Texture 1024x1024

01-22-2004, 10:39 PM
I have a problem:
My program (on windows) use textures 1024x1024 as the background, but it's load my CPU! I can't use OpenGL extensions, because program must work on old videocards.
Light is off.
How can I solve this problem?

I use:
P4 2.4G, 512Mb, Matrox Millenium G450 Dual Head (load ~50% of CPU);
Celeron 667M , 128Mb, i815 (it's integrated) (load ~90% of CPU);

Thank YOU!

Hi !

1024*1024*3 is 3MB, that is a bit to chew on, and then it is going to fill up the entire background and fill the entire framebuffer.

There is not much you can do to speed it up if you have disabled everything you don't need, lighting, depthbuffer test, depth buffer updates and so on.
