提高FPVSIM性能和帧率

本教程涵盖的内容

Start with the Chrome Performance Launcher below, then compare the same track and settings on your computer. The simulator already uses the optimized renderer by default; no special URL or performance mode is needed.

选择任何屏幕截图以全尺寸查看。模拟器屏幕截图显示了早期的界面；使用突出显示的控件作为视觉参考。

Chrome Performance Launcher

Open FPVSIM in Chrome with the browser settings used in our performance testing, without editing shortcuts or typing commands.

ZIP downloads · Requires Google Chrome · Approx. 1280 × 720 page area · Normal Chrome window

1. Download and extract

   Download the ZIP for your computer and extract it. Keep the launcher, quit shortcut, README, and helper files together.

2. Open the launcher

   • Windows: double-click Launch FPVSIM.cmd.
   • macOS: double-click Launch FPVSIM.command.
   • Ubuntu: right-click Launch FPVSIM.sh and choose Run as a Program. If needed, allow executing it under Properties → Permissions. You can also open a terminal in the folder and run bash "Launch FPVSIM.sh".

   If Chrome is already running, save your work, then choose Close Chrome and open FPVSIM. You can also close Chrome yourself and choose Retry.

3. Fly with your FPVSIM profile

   The launcher opens the simulator and reuses your existing Chrome profile named FPVSIM, including its login and controller settings. If there is no matching profile, it reuses or creates a separate FPVSIM profile. Sign in and set up your controller there once.

4. Return to everyday browsing

   Save your work, then open the included Quit Chrome shortcut to close the performance session. Open Chrome with your usual shortcut to restore normal extensions and sync.

What the launcher changes

• Fits the simulator page itself to 1280 × 720 (16:9), with the frame-rate limit and GPU VSync disabled.
• Disables extensions and Chrome Sync for that browser session, and uses a separate browser cache.
• Checks the running browser uses the intended settings and profile.

Your track, camera, physics, collisions, and controller settings stay unchanged. Your Chrome profile is reused, not copied.

The launcher is optional. The flags reproduce our Windows test configuration; macOS and Ubuntu have not been latency-benchmarked. Results depend on your hardware and display, and the flags alone did not show a clear additional latency improvement in our Windows tests. Disabling VSync may increase screen tearing and power use. Compare the same track, and use your normal Chrome shortcut if you prefer its results.

Fine-tune your simulator settings

1. 选择合适的硬件模式

   低规格模式有利于广泛的兼容性。高规格模式公开了教程中使用的渲染分母控件。

2. 逐渐调整渲染分母

   分母越低，图形循环运行的频率越高；分母越高，这项工作就越少。降低值直到场景有响应，但如果您看到持续的抖动或卡顿，请再次提高该值。

   

3. 测试物理线程

   单核物理可以在简单的赛道上提供较低的端到端延迟。多核物理减轻了模拟工作的负担，并且在 Google 地图、湖屋或浮岛等大型场景中可以更加流畅。在您的硬件上测试两者。

4. 观看性能统计数据

   启用性能图并观察图形循环速率、物理负载和内存。如果物理负载持续较高，即使图形数量看起来令人印象深刻，运动也会变得不均匀。

5. 单独检查操控调校

   如果画面流畅，但无人机响应仍过于灵敏或迟钝，请在 Drones 中检查其 PID 设置。PID 调整改变的是飞行响应，而不是渲染帧率；这张旧截图中的数值仅为示例，并非可直接照抄的当前默认值。

   

隔离浏览器开销

1. Use your FPVSIM profile

   The launcher selects the FPVSIM profile and disables extensions for the session. If you launch Chrome manually, use that same profile and keep extensions off while flying; there is no need to create another profile.

2. 关闭不必要的选项卡

   避免在会话期间运行多个模拟器选项卡或其他繁重的页面。

3. 重新测试同一场景

   在干净的配置文件中重新加载 FPVSIM，并将相同的场景、车辆和设置与您的基线进行比较。

Manual setup shown in the video

The launcher above applies these flags for you. If you prefer to configure a Chrome shortcut yourself, the video demonstrates the following alternative.

--disable-gpu-vsync --disable-frame-rate-limit

1. 创建或定位 Chrome 快捷方式

   如果桌面上没有快捷方式，请在开始菜单中找到Chrome，打开其文件位置，然后将快捷方式复制到桌面。

2. 编辑目标字段

   打开快捷方式的属性。将光标放在 chrome.exe 周围的结束引号后面，添加一个空格，然后附加上面显示的参数。

   

3. 通过该快捷方式重新启动

   应用更改，关闭每个 Chrome 窗口，然后使用编辑的快捷方式启动 Chrome。

4. 比较操控手感

   再次测试FPVSIM。这些是不受支持的浏览器标志，其可用性和行为可能会发生变化；如果 Chrome 变得不稳定或停止接受它们，请删除它们。

额外的提示

• 本教程中的 FPS 显示测量图形循环迭代，而不是显示器的物理刷新率。
• 旧界面中显示的物理 FPS 控件在视频描述的 V2 行为中固定为 500；移动旧控件不会改变该值。
• 使用 F5 重新加载可以清除奇怪的会话状态，但它不能取代诊断可重复的性能问题。
• 运行时设置更改可能需要重新加载模拟器才能完全应用其效果。
