You're kidding? Please tell me you're kidding? Their RAGE engine doesn't use GPUs? AT ALL?
It's so CPU bound as to make graphics largely irrelevant - setting all graphics to minimum barely increases the framerate. It's not like you can even apply anti-aliasing either. Despite that they still don't even allow you to max out the graphics because they've imposed an artificial limiter, which can be bypassed outside of the game. Then you can load High quality textures. However, the game is so appalling at loading textures that even within that limit I find them fading in and out in front of me. There seems to be a memory leak, as the longer I play the more likely it is to occur. That's if the textures load at all - sometimes I have to restart the game several times or else 90% of the textures are missing and I can see cars and pedestrians through the walls. Not only that but when I'm speeding along some objects only appear when I'm right on top of them, resulting in me colliding with a fire hydrant and flying out the front of my windscreen.
It has the graphical fidelity of a game from 2003, with performance that makes you want to cry. Crysis Warhead runs better for me. Not only that but they don't have any smoothing on the mouse, which only highlights the lower performance - if you use an X360 controller then it better masks the lower performance. And cars handle terribly on KB&M, being especially twitchy at high speeds. That means I end up using the X360 controller all the time, which is terrible for aiming (though helped from the auto-targeting system).
The game is a wreck, even with the latest patch. It's great fun when it works, mostly (despite some irritating gameplay decisions), and if it performed properly then I'd be happy with it as a game but it was definitely a disappointing purchase.
