I have a machine using qnx rtp with a pci voodoo3 3000. The banshee
driver is being used, but I’m not getting any performance gains with
opengl programs that I’m writing. Today I did a quick comparison test.
I’m using a slightly modified copy of the tk.c file that was in the
mesa demos directory.
The test I did was to load an obj model of a truck (using glm.c from a
glut demo) that is about 27000 triangles. I had it spin, and found the
average frame rate over 100 frames. It was run in fullscreen mode.
I tried it with the banshee driver at 640x480x8 and 640x480x16, and with
the vesa driver at 640x480x8. The results at 8bit color were identical
for both drivers (about 4.7fps) and the 16bit banshee was slower (about
Is there something specific that needs to be done when compiling
software to get 3d acceleration? Or maybe some other system setting?
Here are the compile commands I used:
qcc -Vgcc_ntox86 -I. -O2 -c test.c -o test.o
qcc -Vgcc_ntox86 -I. -O2 -c tk.c -o tk.o
qcc -Vgcc_ntox86 -Wl,-rpath /usr/lib test.o tk.o -o test -L/usr/lib -lGL
-lGLU -lm -lph -lphrender
I tried running the quake3 demo, and it ran pretty smoothly (I don’t
know how to check frame rates in quake), but I don’t know if that means
Thanks for any assistance,
