flew another hop over different terrain (A65 to A69) and FR was choppier dipping down as low as 38...but was in a 1 on 3-4 over eny base with carrier and base puffies + airfield...fight was vertical from 8k down to deck and up for 5+ min with no issues of any kind...accept I appear to have had a connection issue which might have accounted for earlier problem....so all in all you can run hi-res with full detail (all sliders full left) on a 3500+ with this card and should have zero issues...
