I removed CoD from my PC a few months back. It didn't look great or run great and I needed the HDD space.
I just reinstalled today to see how the patches were coming along..... And all I can say is WOW!!
The landscape. The sounds. It looks and sounds so much better the change is incredible!
I still have performance issues.... But I think they're more down to my PC now than anything in the sim (old PC, running Win XP 32-bit. Can't afford to upgrade). Although I still can't fly over London (lack of RAM on the part of my PC I'd guess..... FPS will suddenly drop then CoD freezes and crashes), I can now tweak the GFX setting so that flying anywhere else is smooth as silk.
It looks better. It sounds better.... And most of all it "feels" better than it did.
Ilya and the team have dome great things so far with CoD. Compared to what it was at release it's a whole new game!!
Very happy (...... You may have noticed!!

)
Edit: Meant to ask:
One minor thing that is a little bothersone is that the area under my plane (square in shape) is outlined with a thin black border. I'm guessing it may be the boundary where LOD levels change since the square gets smaller the higher I climb. I'm running an nVidia GTX260 768MB GFX card with up to date drivers (as far as I know!). Has anyone else had this problem and if so have they found a cure for it?
