intel i7 950 @ 3.8 Ghz

Beta 2 (14305) had reintroduced the bad stuttering for me and so I had rolled back to the previous beta1(14214) which gave my system practically no stutters and smooth FPS throughout. (gave feedback in the previous thread for that).
This beta3 (14413) has major performance improvements for me over beta2, but it still does not seem as smooth as the earlier beta1 in this series of patches.
In game settings set to max (except High trees and Low building detail). Epilepsy filter off. SSAO off.
Full screen mode:
Both GPUs on my card are being used and the ATI Crossfire logo appears on screen when actually flying if I turn that on in CCC to check. GPUs are only being used to 60-62% on both GPUs however (using MSI afterburner for the numbers). I have no idea if 60% is good or bad, just including the numbers here for completeness' sake.
Minor stutters are present. Overall it still does not seem as smooth as the beta1 however it is largely playable. I have not tried a mission over London however.
One rider with the stutters though, they can be rather inconsistant in this beta3..sometimes they appeared immensely more noticeable than others whilst testing today...one one flight in particular, they were really bad (rubber band) when low down over a town (Folkstone I think), but generally they have been hardly present at all.
FPS is slightly reduced. Get big slowdowns again when close to another plane (not EVERY time I am close to another plane but frequent enough...this was cured in beta1 for me)..I also get mini freezes when panning view around quickly with TrackIR (also don't recall that happening too often in Beta1).
I am getting terrible flickering in and near clouds as others have reported. If I was not epileptic before I may well soon be if that keeps up
My card is throttling up to full power whilst flying in game, however I never had that particular problem previously anyway.
Vsync is working for me (no tearing when using TrackIR in full screen mode when Vsync on...lots of tearing when it is off).
Seem to have smoother performance with Aero off and with triple buffer on in ATI CCC. Turning Aero off made a big difference in beta1 for overall smoothness.
I have tried most of the Quick missions (except over London) and performance seems similar throughout.
Pseudo full screen
This regresses performance back to beta 2 level for me in regard to stutters...unplayable in this mode.
Hope this is of some help.
S!
