NVIDIA DRIVER 326.84 vs DRIVER 326.80

I did a driver comparison using Fraps in CoD Black Ops 2 multiplayer. Driver 326.84 vs driver 326.80. I was testing because I couldn't figure out why I seemed to be doing much better in the game while using the driver 326.84.

Test setup:

GTX 680 at default clocks, Haswell 4770K cpu at 3.9 GHz, Windows 8.1 Pro Preview 64-bit
In-game AA set to 4x MSAA, resolution set to 1920 x 1080, AO and DoF set to Off, MaxFPS set to Unlimited.

Benchmark was run for 60 seconds in map Hijacked with just me running around. Results:

Frames    MinFPS    AvgFPS    MaxFPS
21044      278           350.733     439      - Driver 326.84 1st run
21454      279           357.567     429      - Driver 326.84 2nd run

21170      278           352.833     432      - Driver 326.80 1st run
21476      282           357.933     438      - Driver 326.80 2nd run

Analysis of results:

1) The differences in MinFPS, AvgFPS and MaxFPS are not significant. They can be explained as normal variance in the different test runs.

2) The 326.80 driver showed a slight tendency to process more frames during the testing.

3) The 326.80 driver had a better IQ. It made things look better than the 326.84 driver.

When I got more kills in the game using the 326.84 driver, the enemy players might have thought I was lagging a bit, based on their reactions to my movements. I'm wondering if I was scoring better with the 326.84 driver because I was processing less frames per the packets I was sending, or because of the worse-looking graphics.
