Isn't that just normal motion blur? Check the wiki.

What is your framerate when this occurs? I've seen this before, but only at 
less than 30fps (in which case its not worth having on anyway). I believe it's 
due to the matrix used to produce the velocity buffer not getting updated 
enough/at all for some reason.

You get the same issue if you set the game speed to 0 or close to it as the 
velocity buffer matrix is tied to the games update rate.

I'm a frequent user of CMT's A30, so I know all about the blur being affected 
at low framerates. I've been trying to pinpoint the cause of visual lag, and it 
usually ends up at being worst when looking directly at the lift. At first, I 
thought the lift was causing lag with it's higher-quality animation. However, 
even with all settings at low-quality/high-performance, I was barely getting 
around 15-20FPS. I have adjusted almost every setting in Windows 7 to be aimed 
at better performance. I also disable dwm.exe when gaming. Two of my processors 
are averaging around 50-85%, while the other two stay below 30%. RAM usage wile 
in-game is around 60-80% (I only have three GB's). General information for my 
laptop model: http://us.toshiba.com/computers/laptops/tecra/R840/R840-S8410

I'm pretty good with computers, so I have tried a lot to improve performance. I 
just need about a thousand bucks so I can buy an Alienware x51.
This bug is especially annoying when trying to explore the user-created maps "

This is caused by the GBuffer shaders using vertex shader constants c96 onwards 
for their own data. I had thought Halo would only use c0 to c95 since that is 
the number of guaranteed VS constants available in shader model 1.0, but it 
looks like Halo can use extra VS constants when available (possibly only on 
custom models).
