Performance
Performance testing are done with either the built-in tools in the game or by playing a replay or a cut scene that's close to actual gameplay and measuring the frame rate per second with FRAPS. Just like Battlefield 2, in Brothers in Arms we actually played a level in a certain, repeatable way, so there are some variances with the results. We ran the game three times and average the results, for each setting and resolution. Even without averaging, the raw scores are very close to one another, usually within 5 %. We haven't done extensive testing with Battlefield 2 yet, so no Battlefield 2 scores (for now).Our test setup
AMD Athlon 64 3000+ socket 939

Gigabyte GeForce 6600GT Silent Pipe graphics card
Maxtor DiamondMaxPlus9 80 GBs Serial ATA 8 MB buffer
ASUS E-616 DVD-ROM
450 watts ATX power supply
Windows XP Professional with Service Pack 2 installed
NVIDIA NForce 4 6.66 reference driver
Creative SoundBlaster Live! 24 bit 5.12.1.512 driver.

all respected games used for benchmarks have been updated to their latest, final builds
The results:
Call of Duty - Dawnville
Forceware 66.93
Forceware 77.72
Forceware 78.01
Looks like we're off to a good start. Performance with the latest Forceware 78.01 is basically the same as with Forceware 77.72. Forceware 66.93 is slightly faster (particularly on 1600 x 1200 with AA and AF), but for all intent and purposes, the three drivers offer the same level of performance.
Splinter Cell - Caspian Oil Refinery. 1024 x 768

Forceware 78.01
Splinter Cell - Caspian Oil Refinery, 1280 x 1024

Splinter Cell - Caspian Oil Refinery, 1600 x 1200
Forceware 66.93
Forceware 77.72
Forceware 78.01
Looks like the shader 'bug' we've seen on the Forceware 71.22 up to 77.72 is still present in the newest drivers. Unlike previous test results, we now see quite a significant difference between the 66.93 and 77.72 / 78.01. Instead of 1 or 2 fps, it's now 4 to 12 fps. Mind you, these results came from the Gigabyte GeForce 6600GT Silent Pipe which has a slightly higher clock than the reference specification. This might explain the performance difference between these and previous results, but it doesn't explain why we're seeing this much performance difference by using a different drivers (particularly since the image output is not the same).
