i am not sure, but you never know until you ask.
i got crystal space and arkanae under linux. now with my geforce 2 gts i just get the lousy framerate of 1.5 to 3 fps. under crystal space i get 14fps with the software renderer. i am using red hat 7.1.
i am not sur if this helps, but i think i saw some module like glx enabled - though i am not sure.
what to do.
thank to you all,
