Modelview matrix orientation slowdown

Has anybody ever noticed a slowdown when the Modelview matrix is oriented in certain directions (I’m not sure which at this time, maybe along y-axis). It seems that when I am oriented in a certain way, my frame rate drops. This happens regardless of what I am drawing and I have seen it in two completely different programs. Any ideas?

I don’t think the modelview matrix is your problem. You should look at what’s to be rendered. Like your polygon count, how large and how many textures you’re applying, what types of lighting you’re using, etc, etc.
