Hi Dark_samurai
Unfortunately the dplay_smooth algorithm has (or at least had) some bugs in it that causes overshooting. The ent_sendnow was suppose to help, but it didn't completely eliminate the problem. The issue seems to be the algorithm doesn't handle rapid changes in motion very well. You might start by just shutting it off, but that presents some other issues.
Here are a couple of MP form threads that might be of interest.
