Hi you all,
I need to do texture subtractions as fast as posible. Any suggestions?

try this extensions:
ARB_texture_env_combine
EXT_texture_env_combine
NV_register_combiners
also glBlendEquation(GL_FUNC_SUBTRACT), on a card that supports none of the above.
It’s part of the imaging subset, so performance may(will) vary wildly from card to card.
