NVIDIA 40.72, GeForce4 Ti4600, & 3DMark

I'm having a bit of trouble lately with 3DMark2001 SE and NVIDIA's newest beta drivers 40.72. Here's my machine for the one's out their that need all the details:

AMD Athlon XP 1900+ @ 2100+
512MB DDR333 Corsair XMS Memory
MSI GeForce4 Ti4600 128 MB
Nvidia 40.72 Drivers
3 Western Digital Hardrives (13.6GB & 2 @ 40GB)
16x10x40 LiteOn CD-RW Drive
16x LiteOn DVD-ROM Drive
SB Audigy MP3+ Audio Card
10/100 Ethernet Card

Running with the 30.82 drivers and this video card, I get the following fill rates and 3dmark score (only listing fill-rate and 3dmark 'cause they are the only ones I am seeing odd results with):

30.82 Drivers:
Single Texture Fill Rate - ~1152 MTexels/s
Multi Texture Fill Rate - ~2232 MTexels/s
3D 2001 SE Mark Score - 10592 3DMarks

Here are my results with the 40.72 Drivers:

Single Fill - 662 MTexels/s
Multi Fill - 662 MTexels/s
3DMark 10462

If anyone knows what may be causing these horrendous fill rates for the new drivers, their input would be greatly helpful!! Everyone is raving about the 40.72 drivers, but I'm just not seeing it here in the fill rates.

Thanks,

I think it may be a 3d mark problem, but if it is, why does the same build of 3d mark show such higher fill rates for the 30.82 drivers?? Another thing I've noticed with the 40.72 drivers, is that the Cg browser crashes alot when previewing different shaders in Nvidia's SDK. Also some of the shaders show horrendous performance as well.
