View Full Version : Hardware Acceleration with OpenGL

Is it safe to assume that any opengl program I run on my computer will be hardware accelerated or does something have to be specified when it's compiled?

I bought an opengl book and I was going through the example programs it comes with. One of them implements motion blurring using the accumulation buffer. The book even says that this is a slow method for motion blur, but it illustrates a point. What bothers me is that it seems too slow when I run it. The scene is composed of a cube and a sphere with the camera rotating around them. Motion blur is applied by rending 50% of the current frame to the buffer and then 5% of the previous 10 frames on top. It drags ass, even on my geforce 4.

Could this be caused by the program not actually using the hardware? I know there are lots of different SDKs available and I'm hoping that this program is going to slow just because it's being compiled with an SDK that doesn't use my hardware... if that's even possible.

that program or thing your running might only be setup to use software cause they dont know if it will be running on a good enough machine to use hardaware.

is there any requirements on the program thats says you need hardware open GL support

It's a demo program from an opengl book. I think it's meant to use hardware. I'm just surprised by how insanely slow it is.

i dunno i would think that its just supposed to run that slow
