well Les, thank you

i guess that wit htime and mroe powerfull CPUS 1600 planes as a limite sounds really reasonable. i cna only believe such a enourmous ammount to be needed to SIM a massive USAAF raid on germany. i remenber reading that something like 1000 bombers and 1500 escorts were used.

CLod would need a 500 limit to be able to sim the BOB i believe. ATM i cnat handle more than 50 or so.

From the quick search I did, the biggest raid on London involved about a thousand German planes (400 bombers and 700 fighters), but I don't know how spread out they would have been in space and time, or how many British fighters met them, so to recreate something like that in a video made using 'Cliffs of Dover' could indeed just require using a couple of hundred planes, which is do-able now.

But to make it playable in real time...it's probably possible to work out what sort of theoretical system requirements you'd need based on how much I had to slow down the game to get decent frame-rates using my current system. Very roughly speaking though, as I had to slow down the game by at least a factor of four, you'd need a system approximately four times faster than what I'm using (GTX580, i7920). At the current rate of hardware development, that's still some years away yet, probably 5-10 years. Which, funnily enough, would fit the projected life-span of the new IL-2 series itself. It fits in too with how long the hardware took to catch up with the previous Il-2 series. So, yeah, if all goes well, we'll finally have the hardware to run the game at decent frame-rates with a realistic amount of planes some time towards the end of the game's life.

Thanks for your nice comments about my videos a few pages back. I'm putting another one up tomorrow...

This is a reference about Allied raids..but can be used as a comparison...

Some of the largest raids employed 1000 bombers to strike targets in Germany. This bomber stream could be as long as 100 miles (161 km) and as wide as 1 mile (1.61 km). At 180 mph (290 km/h) over the target an air raid could last from 35-45 minutes.

With regard to numbers of aircraft needed to be seen in a COD mission emulating raids of the Battle of Britain time frame, I should think that no more than a couple of hundred would suffice. If the Luftwaffe flew a maximum of 1500 "sorties" on some 'maximum effort' days across the breadth of southeast England against geographically separated targets, and over a duration of several hours, clearly no more than a few hundred would be at any specific location-in-space and time.

The USAAF attacks on Germany in 44 and 45 did number in excess of 1000 bombers, and perhaps an equal or larger number of fighters, but that stream of bombers and escorting fighters would likewise have been spread out in time-and-space. Thus, again, even an emulation of an air battle over Germany in '45 would not require more than a few hundred aircraft to be 'spawned' in a COD game/flightsim at any one point in time.

Therefore, I think that the investigation into 'smoothness' of the simulation in handling 1600+ simultaneous aircraft is interesting only in theoreticals. Of course, if it can be shown (tweaked) that such a massive number of aircraft can be generated smoothly, that bodes very well for extremely smooth, non-stuttering air battles of a realistic 300 aircraft or so.

imho

Definitely entering into the theoretical realm at this point, well beyond anything that could be considered realistic.

I could be wrong, but from what I've already seen I don't think the game engine itself will have a problem rendering several hundred aircraft at once, at playable frame-rates, when the hardware is capable of doing so.

And in the meantime, right now, purely in terms of numbers of planes, video's can be made, using the current game, with enough aircraft in them to recreate anything that actually happened during the Battle of Britain. Whether anyone has the skills and commitment to work around the game's other limits and actually do that is another thing.

Hmmmm, tempting. And with the right choice of shots it could even be watchable, if not jaw-dropping. But without the kind of planes that were actually involved, able to fly at the right altitude, over the right kind of locations, it would have to be a fantasy scenario at the moment, and would take a lot of effort to do even then. Too much for me to do in any case, but it certainly gets the imagination going.
