Shadows still flicker in Serious Sam 3: BFE. http://www.youtube.com/watch?feature=player_embedded&v=J08MIHhPoNg This game has been released in November 2012 and it has not been fixed since then. I'm not quite sure if it's driver issue but it looks like. Game performance settings, patches and drivers version doesn't change anything. I'm using Windows 7 x64 SP1. Also any performance improvements for multithreaded rendering for this game would be welcome.
