Thought I'd better post an update to my earlier, perhaps excessively negative note on IL-2 COD.
Eventually - despite my misgivings - it installed, patched & updated, via STEAM.
My rig is Crossfire running 2 x 5850 Vapor-Xs. Contary to earlier rumour I have had no Crossfire issues & framerates seem fine (over water) on "High" graphics settings for everything except aircraft (which I've as far as possible maxed out); buildings & trees (both of which I've set at "Medium" as they are framerate gobblers).
Coming from over water to over land; framerates do initially seem to get jittery; then settle down to quite playable levels. The graphics (particularly water effects) do look lovely; but there are still minor niggles like the Hurricane rear-view mirror stubbornly refusing to appear - & the absence of force feedback. I wonder how much (if at all) immersivity would improve through use of e.g., a Buttkicker Gamer 2 to substitute the vibration effects back in.
The ballastic effects also seem undermodelled when you come to IL-2 COD from BoB2: there seems to be be no bullet drop & in my first few attempts to hose down E/As I invariably shot over the top of their canopies; compensating for seemingly non-existent gravitational ballistic effects.
As other contributors have noted, there is no single player campaign yet; & there is still the issue of needing STEAM running in the background; about which I am not overly confortable. But in terms of the game visually; it runs well on my rig & looks amazing most of the time. No doubt it will improve over time; but as things stand I still prefer BoB2 one to ones & interceptions. I have yet to try a large-scale, multiple aircraft scenario in IL2-COD but will post further comments when I have.
