No, it's not a computational heavy effect. In fact, motion blur is added to make the game look smoother. Low framerates look less janky if you add motion blur. Lost Planet ran like ass on my old PC, but it had so much motion blur it looked decent.
Now i understand, thanks guys :)Originally Posted by RoboPlato
Uncharted 3 had a glitch with the motion blur. It was being calculated but not applied which is why the patch didn't have an effect on the framerate. Motion blur does impact the framerate but not too much on a modern GPU, they're probably doing more than just motion blur in the 30fps build.



This is a sports game, EA should be shooting for 60fps.
