Hello guys, I have every texture quality maxed, and therefore it wonders me why I'm still having this problem. Is it because of the graphics cards or what? - I've already updated my graphics card so its up to date, so it really wonders me why this problem is still there. I've linked a screenshot below of the axe being in very bad details. http://steamcommunity.com/id/Blackflunky1995/screenshot/594701896644674750?tab=all
