i dont have a proper graphics card yet and i dont have the game
but if you want a sharper and more realistic looking graphics it shouldnt be a big deal to fix.
i did some changes in Photoshop but the same changes can be done in the nvidia control panel
all i did was to add some sharpening and a higher gamma setting.
try to higher the "image sharpening" under Color Correction to around 50% (slider in the middle)
and also higher the gamma to something like 1.64 and you "should" get the same effect as in the picture.
Edit: Gamma at 1.16 and image sharpening at 25% (slider 1/4) seems to be best
