# 1. Clear k-buffers entries 1 and 2 to -1.0
#
# The following textures are used:
#
#   Tex 1: k-buffer entries 1 and 2
#   Tex 2: k-buffer entries 3 and 4
#   Tex 3: k-buffer entries 5 and 6

OPTION ATI_draw_buffers;
# this does not matter now, but will matter on future hardware
OPTION ARB_precision_hint_nicest;
