From what i heard of it, it seems that R* doesn't give a rats' ass about this game.
I think its true what you've heard.
The game is buggy and badly optimized. People reporting freezes during loading screens, missing textures, the game doesn't support gamepads (my buddy tried to manually configure his pad, and then he coulnt leave the control menu.) Also your character cant "Side step", so if you hit left or right, he will be running in circles. Mouse behaves very sluggish: if you slowly move your mouse, its movement wont be registered by the game.
Very crappy port.
Also there is a duplicate of a "Shaders" folder in "..Bully Scholarship EditionShaderBinaries", called "Copy of Shaders" lol
