Works nicely here!
I play all settings maxed out (SSAO on as well)- stable FPS, no such big lags when flying through smoke. (2500K, 8gb, 580gtx). Not sure about the numbers, but visibly its just as smooth as IL2:1946 on my machine. Almost anyway- CLOD is still just a touch jerky when when flying along the deck.
My favourite features are: 1. AI - no longer crazy barrel rolls at unrealistic rate. THeir behaviour is much more believable now.
2. Force Feedback - much much better with my MSFF2. Playable without any editing. Really makes the CLOD FM shine too - I can now definitely see that FM is on a different level to rail planes of IL2.
Playing through the original RAF campaign - did about 5 missions on a trot, its addictive.
Great stuff!
