Screenshots look good. I have an ATI card, though, so I'm out of luck.
I've got an ATI card so I also can't take advantage of all the new nvidia beta driver/FXAA excitement.
However, a few months ago I used what I found at this handy thread, JSGME FXAA and SMAA utils
, and I find CloD looks quite good to me (well, except for the ground colors).
I've not flown CloD in about a month (enjoying ROF more), but the "injectSMAA by mrhaandi v1.2 for DX-10" included in the above thread makes CloD look good to my eyes.
Ace-of-Aces makes it really easy to experiment with the various options, so you can try and decide for yourselves which looks best.
