View Full Version : Nehe lesson38, slow fullscreen!!!

Hi All,

I am trying to figure out why Nehe's lesson 38 would be slow when running fullscreen. When running in the default windowed mode, the images fall at an acceptable speed.

I thought it might be because of the pixelformat?? but I have recompiled with "bits" set to 8,16,24, and 32 and this does not seem to help.

I am using a Dell notebook with an ATI M1 graphics chip and 8 Meg of video memory (I know, this is not new technology, but it runs Unreal Tournament at a decent rate so 50 butterflies should not be a problem!!!)

Any help would be appreciated,

I would say that you simply do not have enough Video Memory to run full screen with OpenGL 8mb gets you not alot, and you will also be dropping into software rendering mode. You certainly do not have enough for any texturing either
