What is wrong with the text? Does it look like a jumbled mess of a bunch of numbers/ letters? If so then try lowering the AA settings to lowest settings. There is two different AA settings in game and i think they conflict with eachother which makes the text hard to read. Or if the text is just very blurry/pixelated then it's probably a resolution problem which would mean you need to try raising the in game resolution or turn on automatic screen res.
