《一起开火车2：汽笛重鸣》性能更新

本次更新为《一起开火车2》带来了巨大的技术革新！鉴于部分玩家习惯了《一起开火车1》较低的硬件需求，我们希望大家能在类似的配置下也能畅玩本作。既然《一起开火车2》是一款面向所有人的游戏，那它就应该能随时随地畅玩。如果你之前遇到过运行问题，现在是时候重新启动游戏了！

在1080p最低画质设置下，我们将Intel HD 520的帧率从35 FPS提升到了85 FPS——提升了两倍多！

即便是搭载1.3 GHz Intel i5处理器和集成显卡Intel HD 5000的2013款MacBook Air，现在也能在1440×900分辨率、Vulkan模式下的低画质（甚至不是最低画质）设置中以流畅的60 FPS运行游戏。

对于技术大佬们，以下是重大变更：
- 游戏现在支持多核运行，从而更有效地分配CPU负载。我们通过在一个单独的线程中完全模拟游戏，并在绘制每一帧之前合并更改来实现这一点。这样，即使引擎仍在向GPU提交数据，我们也能继续进行模拟。
- 我们还通过使用模版缓冲区处理描边以及重制水体着色器，显著改善了GPU的工作负载。
- 我们将Godot 4.3.1升级到了最新的Godot 4.5.1。这包含许多修复，以及我们要向引擎提交的第一个PR：

一些额外的小提示：
- 在比较老的硬件上，某些驱动可能无法正常工作。如果游戏无法启动或出现画面错误，我们建议使用Steam中的“Safe Mode”（安全模式）启动选项启动游戏。进入后，你可以自由更改设置，这些设置将在下次正常启动时生效。最重要的是，尝试所有绘图驱动，直到找到最适合你的那个。
- 别忘了尝试开启和关闭垂直同步（VSync）设置。有时开启它能带来极致的丝滑体验；有时则会增加微小的延迟，影响游戏乐趣。

\[Update]

We rollbacked to the last stable release as the update broke the steamdeck by either launching only a black screen or not recognizing any inputs. We're working on a fix as quickly as we can!

The update can be played on the "Performance-Update" branch in the meantime already.

The update is online again with the following hotfix

- Improvement: Much more efficient outline rendering

- Improvement: Update to Godot 4.5.1

- Improvement: More efficient water rendering

- Improvement: More efficient night rendering

- Improvement: Mining rocks on island interchange should be faster on low end platforms

Gameplay

- New: 8 player time mode

Visual

- Improvement: Water and background anti aliasing improvements

- Improvement: Lower splash image screen resolution for 1080p or lower resolution users

- Improvement: Camera transition between map segments is a bit tighter (it starts later and ends earlier)
