Poor performance

OpenGL
1

I’ve already reported the problem that i summarize again here:
i cannot pass attributes, if i pass even a float in this way:
glVertexAttrib1fARB(1,0.0);
performance goes down(10fps), and there is no difference between passing one attribute or 2,3,4,5.
For the moment i pass attributes via glMultiTexCoord3fARB and framerate is perfect(60 fps).
Maybe it’s a problem in driver or configuration:
Radeon 9700, windows2000 and Catalyst 5.3 (last release).
Does someone had a similiar problem?
