The first 90%
“Global” represents a big change for us. Infinite Flight started as a hobby project many years ago and evolved into a full featured flight simulator with multiplayer and ATC, something that no other simulator (desktop or mobile) offers natively. During this journey, we took many shortcuts in order to iterate quickly and do our best to meet the demands of a growing audience.
For “global”, we had to revamp a lot of code due in parts to those shortcuts we took but also to some decisions we made a while back when we were young and stupid. ;)
All of this work is more or less done. At this point we can say that the global update is “feature complete” meaning that most features we needed for global are done and most issues introduced by supporting a full scale planetary terrain (instead of flat small regions) have been solved.
前90％
“全球”对我们来说是一个很大的变化。无限飞行多年前开始成为一个兴趣爱好项目，并演变成具有多人游戏和ATC功能的全功能飞行模拟器，无需其他模拟器（桌面或手机）。在这次旅程中，我们采取了许多捷径，以便迅速迭代，尽力满足日益增长的受众的需求。
对于“全球”，我们不得不将部分代码转换成我们所采用的快捷方式，但是在我们年轻而愚蠢的时候，我们做了一些决定。;）
所有这些工作或多或少完成。在这一点上，我们可以说全球更新是“功能完整”，这意味着我们需要全球化的大多数功能都是完成的，并且通过支持全尺寸行星地形（而不是平坦的小区域）引入的大多数问题已经得到解决。

The other 90%
The biggest roadblocks at this point are performance and memory consumption. Simulating a full scale Earth with accurate topography and 15m satellite imagery takes a lot of memory (RAM) which can cause the app to crash after a little while if we are not careful (the app itself doesn’t crash, the OS automatically kills apps that use too much memory). We currently still have a lot of issues on devices that have less than 2GB or RAM but are working hard to solve those.
About performance, there are still many optimizations we need to do, especially on Android. Recent iOS devices (< 2 years old) seem to be very stable but we still have to improve some bits to make sure we don’t kill your battery. :)
One solution we put in place is to offer a few different rendering quality levels; the pictures we have posted so far are usually from the highest quality with full atmospheric effects.
Our “Low” quality settings are closer to what we currently have in the version that is in the App Store (with satellite imagery instead of repeated textures).
Those quality settings are something that we will continue to optimize down the road as we find better techniques that fit in our performance budget.
另外90％
此时最大的障碍是性能和内存消耗。使用精确的地形和15米的卫星图像来模拟一个全尺寸的地球需要大量的内存（RAM），这可以导致应用程序在一段时间后崩溃，如果我们不小心（应用程序本身不会崩溃，操作系统会自动杀死应用程序使用太多的内存）。我们目前仍然有不少于2GB或RAM但正在努力解决这些问题的设备上的很多问题。
关于性能，我们还需要做很多优化，尤其是在Android上。最近的iOS设备（<2岁）似乎非常稳定，但是我们仍然需要改进一些位，以确保我们不会杀死您的电池。:)
我们制定的一个解决方案是提供几种不同的渲染质量水平; 到目前为止，我们发布的照片通常是从最高质量的全气候效应。
我们的“低”质量设置更接近我们目前在App Store中的版本（使用卫星图像而不是重复纹理）。
这些质量设置是我们将继续优化的道路，因为我们找到更适合我们的性能预算的技术。

Low/Medium Quality Rendering (simplified atmospheric scattering simulation):
低/中质量渲染（简化大气散射模拟）：

High Quality Rendering (full atmospheric scattering simulation):
高品质渲染（全大气散射模拟）：

But really, when is the update?
We really don’t know. There are still a couple of problems to which we don’t yet have a clear solution for, so we can’t estimate the time it will take to implement.
That being said, our current target is to ship this update - WARNING, HIGHLY SPECULATIVE - during summer. Please understand that this is subject to change.
但真的，什么时候更新？
我们真的不知道。还有几个问题，我们还没有一个明确的解决方案，所以我们无法估计需要实施的时间。
话虽如此，我们目前的目标是在夏季运送这个更新 - 警告，高分辨率。请谅解，这可能会改变。

One more thing
We mentioned this in the past but we wanted to reiterate: the 15m satellite imagery (what you see in most preview pictures so far) is limited to certain areas of the world at the moment; here is what is covered so far:
还有一件事
我们过去提到过这一点，但是我们想重申一下：15米的卫星图像（到目前为止，大多数预览图像中看到的）只限于世界某些地区; 这是迄今所涵盖的内容：

More precisely, the area covered by 15m satellite imagery are:
Australia and New Zealand
Contiguous United States 48 states (CONUS)
Alaska Mainland and Hawaiian Islands, US
Canadian provinces of Ontario, Manitoba, Saskatchewan, Alberta and British Columbia
Western Europe and surrounding area (33 countries)
Japan, Taiwan, North and South Korea
Israel, Syria, Jordan, LebanonLibya, Egypt, Tunisia, Morocco, Algeria, Western Sahara
Turkey, Iraq, Iran, Afghanistan, Pakistan
Arabian Peninsula (Saudi Arabia, Yemen, Oman, Qatar, Bahrain Kuwait, UAE)
Sudan, Somalia, Ethiopia, Eritrea, Djibouti
It would probably take many months of non-stop flying at high speed to explore all of it but we wanted to set the right expectation.
The imagery for the rest of the world is very low quality at the moment (500m/pixel, looks very blurry) but the topography (elevations) is accurate (between -60 latitude and +60 latitude) and will still have airports to explore. Our plan is to gradually improve the quality of the remaining areas as we are able to acquire new datasets.
We can’t wait to finally release this incredible update that will take Infinite Flight to the next level. Our team remains hard at work and appreciate any show of support you can spare to help us through the remaining problems we have to solve.
更准确地说，15米卫星图像所覆盖的地区是：
澳大利亚和新西兰
美国48个州（CONUS）
阿拉斯加大陆和夏威夷群岛，美国
加拿大安大略省，马尼托巴省，萨斯喀彻温省，阿尔伯塔省和不列颠哥伦比亚省
西欧及周边地区（33个国家）
日本，台湾，南北韩
以色列，叙利亚，约旦，黎巴嫩利比亚，埃及，突尼斯，摩洛哥，阿尔及利亚，西撒哈拉
土耳其，伊拉克，伊朗，阿富汗，巴基斯坦
阿拉伯半岛（沙特阿拉伯，也门，阿曼，卡塔尔，巴林科威特，阿联酋）
苏丹，索马里，埃塞俄比亚，厄立特里亚，吉布提
可能需要几个月的时间不间断地高速飞行才能探索所有这一切，但我们想要设定正确的期望。
世界其他地区的图像现在质量非常低（500米/像素，看起来很模糊），但地形（海拔）是准确的（纬度-60纬度和+60纬度之间），仍然有机场可以探索。我们的计划是逐步提高剩余领域的质量，因为我们能够获得新的数据集。
我们迫不及待地终于发布了这个令人难以置信的更新，将无限飞行提升到一个新的水平。我们的团队仍然努力工作，欣赏任何支持的支持，可以帮助我们解决我们必须解决的剩余问题。

搬运完毕顺便吐槽一下机翻

高画质的卫星图像地景暂不覆盖中国
最有可能的更新时间是今年夏季。
也不排除提前和跳票，不过今年7，8月可能性最大

对于IOS设备来说，购买两年内的或是1G运存的可以用稍低画质运行，但真正想要高效不掉帧还是2G运存起步。对于安卓机型来说，因为不同于IOS设备的运行机制，所以开发团队目前就对安卓设备的优化花了很多时间，因为新的版本很快可以吃满安卓设备的内存并且导致系统自动结束程序进程，导致IF崩溃。

明明就是你看不懂了

那安卓要多大的运存？6g？8g？
