opengl issue


hi,

i just installed cygwin with xfree86 on my ibm laptop a31 with ati radeon mobility 7500. i am able to run glxgears and compile my linux opengl codes to use windows opengl and glut.

the problem is that I apparently get only software renderer for opengl instead of dedicated acceleration (note: I installed IBM display drivers) - because glxgears displays only ~400fps, whereas I used to get 1500fps on the same machine with linux.

is hardware acceleration not there by philosophy of cygwin/xfree86 or I can download somewhere proper libraries for cygwin and my gfx card? I see /lib/win32/*.a which I link against (-lopengl32 -lglu32 -lglut32), but these I guess are shortcuts for software renderer.

I havebt found anything conclusive in docs, only some remarks of using windows dll's - maybe that's the way? is there a way I can use hardware acceleration that DOES EXIST on the system already?

Any comments would be more than welcome.
Thank you
Dominik
