LightBoost is good for 2D too.
There was a tweak discovered in the last few months, to allow LightBoost to be used without 3D. It is a strobe backlight that flickers like a 120Hz CRT --
see high speed video of LightBoost -- so you get the CRT perfect clarity effect, with fast pans that look as crystal-clear as stationary images. This is the first time an LCD has truly achieved this for gaming, thanks to LightBoost.
The thing is nVidia bundled LightBoost with 3D. Which not everyone is interested in. Fortunately, a tweak was found to enable LightBoost for 2D, without needing to enable 3D. See
TFTCentral.co.uk: Motion Blur Reduction Backlights Including LightBoost, as well as other
media coverage as well as google "LightBoost". Instructions are found in the
LightBoost HOWTO. The good news is that the difficult hack method is being replaced with the new ToastyX easy method (see hyperlink at the top of the 'Hack' section), which takes only 3 minutes to do to enable LightBoost for 2D, without needing to buy a 3D kit.
Be noted that LightBoost can degrade colors because it was pre-calibrated for 3D usage, but can also be adjusted (via nVidia Control Panel, or google "lightboost crimson fix") to get most of the original color back. There are many rave reviews about motion clarity -- see
some reviews listed on this page. Make sure, though, you are able to run at 120fps@120Hz, or LightBoost doesn't really benefit enough to compensate for the slight color downgrade.
