Just downloaded and applied Les's SweetFX modified files. "Works a treat", as they say in Old Blighty, or Oz, or wherever they say that.

However, as I was trying it out on a quick mission free flight in a Hurricane over the coast of England, I noticed there is still considerable flickering jagginess at certain spots, most notably the Chain Home radar towers on the coast, and also a little at the edges of the cockpit windows. I tried disabling anti-aliasing in the game video menu (someone said to do this), but it didn't seem to change. Should I be disabling anti-aliasing in the game video options? Or is something tweakable that would improve this in SweetFX?
Many thanks for your files, Les!
