You folks forgot ONE THING there.. I said "someday", which can be even after years.
oh.. or did I forget that there will be no new technology available for graphics anymore?
Hangtime: Are you going to use your voodoo,tnt2 or geforce still after few years? poor you.
Did you also notice that I said simulator in no particular meaning?
But not even grandpa like you, hangtime, can't say that you wouldn't like to see that sort of details someday in a simulator.
Currently you could have more detail in planes than AH has, and even more detailed textures.. I'd say that it would go between 5000-10000 polygons, which begins to look pretty good already, but for older graphics cards and computers, no eye candy with that accuracy. (btw. WB III will use 3000-5000 polygons on the planes, if they get it done)
That tank probably has 70000 polygons

Well.. that would run fine with couple tanks and simply terrain

But anyhow, it wont take us long to have graphics cards available that can run game with 40000 polygon models.
(Hangtime, take a little history lecture while you moan about frame rates; that stuff gets more advanced every year, currently it is too much, but in the future, NO)
