JudasIscariot: You can try running it without having QuickTime installed but make sure to install it somewhere on C:\ :)
Crsldmc: It worked without QuickTime, hence why I asked if having it would increase quality or something, as the game runs smoothly without atleast on my system, so if installing it will bring the same perfomance as without it I don't see the need of having another program taking space in my PC. :)
Thanks answering Judas!
