The game is EXTREMELY lagging on my PC and I am blaming the inability to turn off shadows and other quality for that. I will have to wait to make them toggleable instead of choosing "Fastest, fast", etc because they don't seem to do anything.
EDIT: My specs are:
R5 230 Graphics (Very poor but can run most old-medium games with SHADOW OFF!)
8GB RAM, Intel code i5 4460 3.2ghz.
