It is no surprise that P4 with SSE2 drivers accelerates some OpenGL performance tests. OpenGL uses vector math for everything. If there's anything about 3D graphics that requires double-precision floating-point, I'd like to know what. The people who designed OpenGL produced many generations of machines using only single-precision datapaths in the graphics pipeline. That means the Nvidia drivers might be optimized for SSE, not SSE2. And there's no reason Nvidia couldn't have a similar driver optimized for AMD's 3DNow!.
