The testing where I noticed a drop in frame rate by switching to DX11 was when I was testing with 0.4.2 trying to fix that horrible timewarp judder, as the vsync behaviour seems to be quite different between DX11 and DX9 it may just have been an artifact of that. Ideally I'd sit down with vsync disabled in both and do a raw performance profile between the two, but as DX9 is hosed at the moment that isn't possible.
