Xasthur, you're right about the water. I forgot to mention that in my last post. AH has better land, IL2 better water.
Panos: It's hype. HTC doesn't share this kind of stuff. In all my time of reading the AH forums (since after AH left BETA) I haven't run across any reference to "floating point models."
He's using his own made-up terms to describe something HTC has never talked about, so he's BSing to make TW look better.
Most folks in TW have left, given up hope, or out and out QUIT because the engine is so terribly buggy, inaccurate, and limiting that they can't do what they want with it. The "next version" has been in the works for 6 years, and in fact the main coders have left so it's never coming. The base code engine is so limiting that large amounts of drag are hard-coded into cooling flaps, regardless of which plane and which cooling flaps are in use. Durability of a plane part is directly linked to the weight given to said part, as well. Many plane builders have complained about these and many other bugs in the TW forums.
TW is so flawed on even the most basic levels that it will never be "accurate" as most TW folks claim. I think TW caters to the minority group that likes fiddling with engine settings, only....
They're not accurate settings!! It's plug-and-play! They plug in the power of the engine and a few other settings, and expect it to generate a perfectly accurate power curve. Most planes plug in the most basic values for the engine but then don't even include the WEP, max, takeoff, cruise, continuous throttle settings for the engine, meaning they never tested them in the first place. Which means they only compare top speeds, they aren't very accurate.
It's like trying to duplicate the Mona Lisa with legos. Only you have to use the ones you have. And you don't have many. You can come up with some things that might resemble it (what TW is now) but it is nowhere near accurate, and claiming it is (what TW fanatics say now) is absurd to anybody outside looking in.
My little $0.02 rant.
