NVIDIA 310.14 beta has large negative impact on TF2 performance
The NVIDIA 310.14 beta (from nvidia-experimental-310 package), which is said to carry a number of performance improvements[nvidianews.nvidia.com] and is the recommended driver version for Ubuntu users, actually has a large negative impact on TF2 performance over NVIDIA 304.51 (from nvidia-current-updates). Meanwhile the Openbox window manager continues to have a slight advantage over Unity.

No newer NVIDIA drivers were available in the Ubuntu (quantal) repositories at the time of testing (Mon 26 Nov 2012), and I couldn't get Steam games to work with a manually installed NVIDIA 310.19 version[www.geforce.com] either. I'll look further into that in the future, but if anyone's got any experiences/advice, please share.

Anyway here's some of the timedemo benchmarks I've made:

unity - nvidia-current (304.51)
benchmark00: 183 frames 3.298 seconds 55.49 fps (18.02 ms/f) 15.797 fps variability
benchmark01: 864 frames 7.874 seconds 109.73 fps ( 9.11 ms/f) 20.261 fps variability
benchmark02: 115 frames 0.623 seconds 184.64 fps ( 5.42 ms/f) 54.990 fps variability

unity - nvidia-experimental-310 (310.14)
benchmark00: 183 frames 4.679 seconds 39.11 fps (25.57 ms/f) 14.251 fps variability
benchmark01: 864 frames 15.568 seconds 55.50 fps (18.02 ms/f) 14.798 fps variability
benchmark02: 115 frames 1.935 seconds 59.43 fps (16.83 ms/f) 10.583 fps variability


openbox - nvidia-current (304.51)
benchmark00: 183 frames 2.833 seconds 64.60 fps (15.48 ms/f) 17.116 fps variability
benchmark01: 864 frames 7.413 seconds 116.55 fps ( 8.58 ms/f) 18.990 fps variability
benchmark02: 115 frames 0.566 seconds 203.35 fps ( 4.92 ms/f) 49.844 fps variability

openbox - nvidia-experimental-310 (310.14)
benchmark00: 183 frames 4.004 seconds 45.70 fps (21.88 ms/f) 15.923 fps variability
benchmark01: 864 frames 15.423 seconds 56.02 fps (17.85 ms/f) 15.832 fps variability
benchmark02: 115 frames 1.925 seconds 59.73 fps (16.74 ms/f) 16.319 fps variability

There are stable 310.19. Use it.

There is a PPA with the cutting edge drivers that is called xorg-edgers.

This looks like as if vsync is enabled with the newer driver.

You are very unspecific as to what your settings have been both in nvidia-settings and in-game.
