Is there anything to be done about the artifacts seen around the gun when running in stereoscopic 3D?

Can you explain the artifacts?. Are you sure it's not motion blur or another game effect?. I often see anomalies in 3D Vision gaming, even 3D Ready games. Maybe nvidia will update at some point in the future with a Crysis 2 profile?, although, as far as i am aware Crytek have done there own 3D technology which supports nvidia's 3d tech.

Each eye sees an area around the gun that appears to be a transparent outline of the same shape where the other eye sees the gun geometry.

The background is filled in on each eye's transparent section but it is not aligned properly with the real background.

In the screenshot above, look at the iron sight at the end of the gun, the tip of the barrel and the near sight.
