I've been trying out Rate v Angle with these settings and, to me, it feels like it's recreating the motion instead of simulating it. Could do with tuning, but this is my base DCS settings.
MSFS acts similar to DCS. but can't get the same in IL2, as roll rate induces pitch only.
It takes some getting used to, it's quite violent but feels smoother in motion, anyhoo I'm digging it. YMMV
