Texture writer slow

anybody experienced the texture writer being veeery slow on some systems?
i use an athlon 3500+ 64bit system and geforce 6800gt graphics adapter. but saving the textures to disk is way slower than on my laptop or on an intel mac … same patch, same texture size …

thanks for any tips.

Have you tired the screenshot writer, text
Its loads faster, and seems to work with non power of 2 textures now as well!

i would have if i didnt need to capture 4k textures …

agp or pci-express cards?
