But there's definitely no performance downgrade compared to other cards.
What is it that makes a flight sim so CPU limited? I've never really understood that.

How can hundreds of AI soldiers in an RTS or dozens of bots in a first person shooter (with realistic physics) run at 80+ fps when Flight Simulators seem to be stuck in the 20s indefinitely?

How can they be THAT CPU heavy with a single object moving through the air?

If they are actually simulating the movement of air over the wings, I can see how that'd bring a decent CPU load... but looking back at the numbers, it still seems like a bit of a stretch to think that the fastest cpu on the market can barely manage 30fps average.
