Found these screenshots by Jaws2002 over at the IL2 forums in a thread discussing Rise of Flight. Not too shabby :). You can now purchase the Pfalz D.IIIa in the Rise of Flight store.
Be sure to click on the images for a much higher resolution version!
Edit: And these last two shots are not of the Pfalz in action (doh), but the Albatros D.Va (thanks athlondude for the correction).
