The game performs a lot better at fullscreen, makes no sense for me and it is annoying. I cant inject SpecialK and make it work proper at fullscreen, it adds a border to the window.
Tip for nVidia Users: Force AF 16x in control panel, and delete the shader compilation cache. This will fix AF and will not have that weird textures behaviors in game.
rant that pre-shader compilation has all the makings of a lazy port. I know all games need to compile shaders on you machine, never seen one doing all at once like this (except CEMU, a emulator).
