after registering the environment variable forllowing were the results:
hw_available Is it possible to create hardware surfaces? AVAILABLE
wm_available Is there a window manager available NOT AVAILABLE
blit_hw Are hardware to hardware blits accelerated? AVAILABLE
blit_hw_CC Are hardware to hardware colorkey blits accelerated?AVAILABLE
blit_hw_A Are hardware to hardware alpha blits accelerated? AVAILABLE
blit_sw Are software to hardware blits accelerated? NOT AVAILABLE
blit_sw_CC Are software to hardware colorkey blits accelerated? NOT
blit_sw_A Are software to hardware alpha blits accelerated? NOT AVAILABLE
blit_fill Are color fills accelerated? AVAILABLE
I've nVidia GeForce 2 MX 200, doesn't it support the rest of the
functionalities (I am particularty interested in sw to hw blits). or am i
missing something once again?
