你能真正获得的帧数
没有神奇的配置。Unity 播放器真正读取的三个启动标志，真正消耗帧数的图形设置，以及一份大家复制但毫无作用的标志的简短列表。

两个答案都会改变下方的启动选项和设置列。
6-8 core CPU, 16-32 GB RAM, mid-tier GPU. Target: 100-144 FPS at 1080p/1440p.

Steam 库 → 右键点击 Rust → 属性 → 通用 → 启动选项。三个标志，每一个都有实际作用。
-window-mode exclusive -gc.buffer 2048 -force-d3d11-window-mode exclusive
Forces true exclusive fullscreen instead of borderless, which removes the desktop compositor from the present path and measurably lowers input lag.
-gc.buffer 2048
Bumps the garbage-collection buffer to 2048 MB so the client collects less often, which is what most Rust stutter actually is.
-force-d3d11
Pins the mature, well-optimised DirectX 11 renderer, which is also the path Nvidia driver threading and Reflex are tuned for.
On Nvidia cards, set Reflex to "On + Boost" in the graphics options: it cuts end-to-end input latency by up to 38% by keeping the render queue from backing up, and it costs you nothing in average FPS.
8 个滑块，按性能消耗排序
针对 Mid-range 档的推荐。图形菜单中的其他设置相比之下都不重要。
| 设置 | FPS 影响 | 推荐 |
|---|---|---|
| Shadow Quality Shadow cascades are the single most expensive thing the Rust renderer draws, so cutting them back frees more frames than any other slider. | 高 | 1 cascade, short distance |
| Grass Displacement Displacement recalculates the grass mesh around every moving player each frame, so it costs FPS exactly when a fight starts. | 高 | Off |
| LOD Bias / Object Quality LOD bias decides how early high-poly meshes swap down to cheap ones, which is what dictates your draw-call load inside bases and monuments. | 高 | 0.75-1 |
| Water Quality + Reflections Real-time water reflections re-render the scene a second time, so leaving them on can halve your frame rate on any coastal base. | 高 | Simple, reflections off |
| Anti-Aliasing FXAA is a cheap post-process pass while the temporal modes cost real frames and smear moving targets at range. | 中 | FXAA |
| Graphics Quality This is a master preset that silently re-enables the expensive sub-settings, so set it first and only then tune the individual sliders. | 中 | Good |
| Draw Distance Draw distance is mostly a CPU cost, and dropping it too far trades frames for losing long-range spotting you need in open terrain. | 中 | Medium-High |
| Occlusion Culling Culling spends CPU time to skip hidden geometry, which is a clear win in dense bases and monuments but can lose frames in open fields. | 视情况 | Test both ways |
流传多年，仍然无效
这些出现在网上的每个启动选项列表中。Unity 播放器不会读取它们。
-high
Cargo cult: the Unity player does not parse this flag, and Windows already schedules the foreground game sensibly — forcing high priority mostly starves the audio and network threads.
-USEALLAVAILABLECORES
Cargo cult imported from Unreal Engine games; Unity does not recognise it and already threads its job system across every core it can use.
-malloc=system
Cargo cult copied from Unreal Engine launch-option lists; Unity does not recognise it, so it changes nothing about how Rust allocates memory.
按 F1 打开控制台并输入 perf 2 在更改任何内容前后。它会显示 FPS、内存和垃圾回收统计，这是判断标志是否对你的机器有影响的唯一诚实方法。所有这些都取决于补丁：Facepunch 会重命名图形选项，Unity 播放器也会在渲染器更新后悄悄停止遵守启动标志，所以在大客户端补丁后请重新检查。控制台的其他内容请参阅 命令参考.
