can i use nvopengl.dll instead of opengl32.dll ???

[T2k]

if so, how do i do this, and is there a performance boost ???

This is the driver for your card, and it's automatically loaded for you. It's opengl32.dll that does this job for you.

No way.
ICD does not export OpenGL functions.
It has speciall interface to communicate with opengl32.dll
