Battlefield 2142 gun shaking

I recently purchased BF 2142 and it has been working great with the exception of one thing. Sometimes when my character runs the gun jolts up and down as if I am sprinting then stopping. It is extremely annoying to look at and i was wondering if anyone knows of a fix to it. I was thinking it was my computer but everything else about the game runs well and smoothly. Thanks for the help in advance.

 

So does no one have any idea how to fix this?

 

that sounds like very bad lag...what servers are you on? sometimes i get that problem when i am running next to someone with high lag too...so even if yours is around 30 youl still get it if your near someone with more than 50....

 

make sure you go on the servers with the green latancy button and check your lag in the screen that pressing tab brings up
