@Fasy X: I know right. It's because of the "PCSS Ultra" setting, the accuracy of shadows and their draw distance is just insane! You'll notice from a viewpoint that shadows are visible for objects as far as you can see. Combining that with an enhanced version of HBAO+, high-quality anti-aliasing and the genuine feel of the Victorian era works like magic.

Note: I'd recommend using MSAA4X +FXAA option, produces the best results in my opinion. Cloth physics are locked to 30 FPS, you can change that by adding "FlexibleMotionSimulationFPS=1" under [OPTIONS] in AC.ini file located in Documents\Assassin's Creed Syndicate.
