I was expecting that too, but really it wasn't bad at all and still very playable. I play on a 40" TV.
Turning vsync on made things smoother for sure, but it wasn't a deal breaker.
But I only fly ww2 stuff, primarily the 109 which I'm betting are a tad bit less stressful than the jets? I know the one time I sullied myself with a jet flying the mig-21 it was very jittery.
