Hy,
I play with resolution 800*600

I played with Medium crosshair, but now i change it on small.
now:
small - is good for secondary werapons, but 4 primary are ........
medium - is good 4 primary weapons but 4 primary not right

Go on 640*480 Large green !

640*480 large green ftw ;)

Just practice. the crosshair is just there to help you aim.

640x480 large best

800x600 for one shot ! 640x480 for spray !

640x480 medium it´s for all the best ! spray and oneshot
you will see!

640x480 medium ;);)
