I remember scathingly refering to CFS1 as 'The Hang-glider Sim', because of the way the planes were supposedly doing 300mph ten feet off the ground but looked like they were doing 20mph, and felt like gliders during maneouvers.
I'm aware of the old rationale about having to be able to draw the scenery at acceptable FPS, but IL2 was doing an acceptable sense of realistic speed years ago. But then this is the CFS3 engine, and I guess they were still limited by the hardware back then.
But it doesn't explain the flak-bursts. Trees go by a lot faster on the deck, and there are lots of them without detriment to FPS. So how come a handful of flak-bursts need to be going so slow (or fast in fact, being that the plane is over-taking them at 3mph, which means they're going at the same speed as the plane minus 3mph)?
It's not just the far-away ones Olham, it's the ones you can fly through as well. It's very very weird, when you think about it.
Clouds do it too, I should add. Next time you're flying through a cloud, notice how slowly the mist is passing you. It's like you're at walking speed. It creates a surreal sensation of no speed.
