Is this card compatible with 3D acceleration? The "nv" driver that comes with XFree86 does not support HW 3D acceleration, but it should still work unaccelerated with the OpenGL libraries and glx module that come with XFree86. NVIDIA's binary drivers will replace XFree86's GLX module and OpenGL libraries with ones that support HW OpenGL acceleration on NVIDIA hardware. > 4. Should the examples from www.opengl.org run in a non-accelerated card? They should run with even with the software OpenGL rendering used by the "nv" driver.
