I just did a test after applying the Russian patch to the Russian games version and the big surprise on my config (quad 3GH, 8 gig ram, 6970 2 gig ram, win7 64) the game (1680x1024 resolution) is fluid all options to max, almost no micro saccade, smooth over the countryside and villages, some delays on towns and it's 200 to 300 above ground! I have not tested on London.
The paradox is that now on my config the game is more fluid with options at max with shadows that with medium settings and no shadows where I have no gain from the game unpatched!
Could this be the missing link between the "alternate universe" the team is playing their game in and our world? This could be a huge discovery actually. Anybody else know what the Russian version is performing like post patch?
