Not knowing which model you have I would go into settings, game mode on, when gaming. If your tv allows it then adjust amp settings to low or medium depending on source. AMP high can intoduce problems as in judder, or TBE on tv sports or fast moving scenes. If I remember, game mode removes the extra processing of the tv which may be your problem.
I have recently purchased the new Samsung LED LCD TV, and had a few questions concerning the Auto Motion Plus feature. I have been told that I should only use this feature for high speed action sequences or sporting events. Is this good advice? I am wondering about using it while playing a video game, or watching films in HD. I have found that when watching a film without a lot of action, where the camera is handheld, characters seem to be seperated from there backgrounds, like cardboard cutouts (but smoother). And when playing a game on my PS3, character movements actually seem jerkier, not smoother. Is this normal? Should I have the auto motion plus feature turned off when I play video games and/or watch non-action packed films? Or are there optimum video game/film settings for this feature? Thanks!
