If you have to choose between prettier graphics and a faster framerate, there's always going to be a large group of people who go for prettier graphics.I remember when console gamers swore until they were blue in the face that frame rate didn't matter and 30fps was perfect. I'm glad more people are getting to enjoy games at a proper frame rate this generation.
The beauty of the FPS Boost (and patches or PC) is you don't have to choose. Makes it easy to enjoy!
