Texture creation is too slow (textures are shadowed to RAM)

Hi!

I’m using the latest NVidia driver and my problem is that textures are created very slowly. I think it is because they are copied to the main memory. I also tried Pixel Buffer Objects but the glTexSubImage2D works only with 25MB/s. The program is available at texbind2.c . It takes 1.8 secs on my AMD 1800+ AGP 4x system with FX 5600. Does somebody have any idea how could I disable shadowing of the texture memory? (or measure the performance of my test program)

I was wrong… the problem was that I used RGBA colorspace instead of BGRA.
