In another fascinating insight into the workings of Flight Simulator X , Phil Taylor’s latest blog entry explains exactly why Autogen has such a dramatic hit on performance:在另一项有趣的洞察到运作的飞行模拟器X的 菲尔泰勒的最新博客条目解释,正是autogen有这样的戏剧性创下的业绩:

Now, a typical scene has 50 1km x 1km cells in the scene.现在,一个典型的现场已五○一公里x一公里细胞在现场。 Autogen trees are pegged at 4500 max per cell (when the slider is all the way to the right). autogen树木挂在4500的最高每细胞(当滑块是所有方式的权利) 。 You can set the max up to 6000, so let’s call it 5000 for easier math.您可以设定最高达6000 ,让我们的呼吁,它更容易为5000数学。 5000*50=250,000 trees. 5000 * 50 = 250000树木。

Holy Autogen Batman!圣autogen蝙蝠侠! Yes, this is why autogen brings the system to its knees.是的,这就是为什么autogen使系统瘫痪。 Crysis doesn’t try to render 250k trees. crysis不会尝试,使25万棵树木。

Now, as much as I admire the team for their creation, I really do have to ask myself why these calculations weren’t done a few years back during development!现在,虽然我佩服队为他们的创造,我真的要问自己,为什么这些计算没有做了几年,回到期间的发展! In Phil’s (and the team’s) defence, he does confess that they should have done so and at least they’re looking at them now.在菲尔的(和团队的)辩护,他并不承认,他们应该有这样做,至少,他们正在寻找他们的现在。 And it’s good to know WHY it has such a performance hit.和它的好知道为什么有这样的表现击中。
