Crysis: See a "line" when moving around

I'm not sure if it's my computer or incompatibality but I always have this line of separation whenever I play crysis. I don't have a screen shot but I believe you can roughly visuallise .

So, is there anyway to resolve the problem? While I can live with it, it's rather annoying.

PS: this does not happen in Team fortress 2/portal/Half life 2 (orange box, basically).

Thank you in advance!

Do you have SLI/Crossfire?

Sounds like tearing (a problem seen on LCDs) - looks like its cutting two slightly offset images in half and pasting them together?

Try looking for a setting like "vsync", "image synchronization", or something like that, and turn it on - should fix the problem (may or may not cause a noticeable performance hit though).

Not sli/cf.

OH ****! Too used to playing Stream games where they allow vsync. Thanks pdehn!

How dumb of me...
