Thanks! Can you also tell me your settings?
Sure

Anti Aliasing: Multisampling 4X, checking the enhance in-game AA settings and the Gamma correction.
Anisotropic filtering: 16X
Texture filtering: High Quality
Negative LOD Bias: Clamp
Vertical Sync: checked and on, also using the triple buffer option
I used to have my AA on super sampling with transparency, but i didn't really notice that much difference in the Anti aliasing unless i zoomed out quite a bit, so for me 4X AA is enough
