阅读13分钟潜行者2鼠标延迟、瞄准不跟手，多半来自游戏自带的鼠标平滑与视角加速没关、Input.ini 还在走引擎默认值，再叠上系统指针加速和外设回报率。
鼠标本身大多没坏，多数情况不用换外设或重装系统。以下方法在 Windows 10/11 实测可用，每改一项就退回主菜单重进存档，试一次手感。
适用系统：Windows 10/11；最后更新：2026-09-28。
鼠标发飘、瞄准不跟手，多半是这三层在叠加延迟
游戏会把输入设置写在 C:\Users\你的用户名\AppData\Local\Stalker2\Saved\Config\Windows\Input.ini，如果文件里 bEnableMouseSmoothing 还是 True，转视角就会带一层迟滞。桌面鼠标也发飘的，多为控制面板里 提高指针精确度 没关；只有游戏里发飘的，问题在游戏内设置或配置文件默认值。可以先看下面这张图里的几个方向，对照自己的现象判断。

先分清是游戏平滑、Input.ini 默认值、系统指针加速还是外设回报率在拖后腿，再对症处理，能省下大量换鼠标和重装系统的时间。
方法1 游戏内先关掉鼠标平滑与加速
进游戏设置里先把平滑和视角加速关掉，这一步在游戏里就能做，做完多数人手感就有变化。鼠标平滑会把手部的小幅移动做插值，转视角就有拖影迟滞；视角加速让准星速度随转动幅度变化，瞄准很难跟手。
操作步骤
- 游戏里按 Esc 暂停，或退回主菜单，打开 设置 → 控制（Controls）
- 找到 鼠标灵敏度，在默认值基础上小幅下调，别一路拉满
- 把 鼠标平滑、鼠标加速、视角加速 这类开关逐项关掉
- 水平与垂直灵敏度先设成同一个数值，再分别微调
- 改完退回主菜单，再重新进存档，否则设置不写进配置文件
灵敏度调得越高，手部很小的移动就会被放大，准星容易飘过目标；先关平滑与加速、再把灵敏度小幅下调，通常比一味调高更跟手。

方法2 编辑 Input.ini 彻底关掉平滑与加速
界面开关有时盖不住引擎的默认输入设置，直接改 Input.ini 最彻底。这个文件在 AppData 里，默认是隐藏的，路径随启动平台不同而分开。
操作步骤
- 打开 文件资源管理器 → 查看 → 显示 → 勾选 隐藏的项目（AppData 默认不可见）
- Steam / Epic 版路径：C:\Users\你的用户名\AppData\Local\Stalker2\Saved\Config\Windows\Input.ini
- XGP / WinGDK 版路径：%localappdata%\Stalker2\Saved\Config\WinGDK\Input.ini
- 先复制一份备份，改名为 Input.ini.bak，改坏了能还原
- 用记事本打开，在文件末尾另起行写入 [/script/engine.inputsettings]、bEnableMouseSmoothing=False、bViewAccelerationEnabled=False
- 另存为时文件名保留 .ini，编码选 UTF-8 无 BOM，别存成 .txt
- 重启游戏生效；进不去就把备份改回原名覆盖回去
bEnableMouseSmoothing 管的是鼠标平滑，bViewAccelerationEnabled 管的是视角加速，两行都改成 False 才算真正关掉。文件末尾如果没有 [/script/engine.inputsettings] 这一节，自己补一行，参数才会被引擎读到。

方法3 关掉系统指针加速和全屏优化
系统层的指针加速会在游戏之上再叠一层延迟，桌面上鼠标也发飘，基本就是它在起作用。全屏优化同样会接管游戏的画面呈现方式，让输入慢半拍。
操作步骤
- Win+R 输入 control 回车，打开 控制面板 → 鼠标 → 指针选项
- 取消勾选 提高指针精确度，确定后再进游戏试手感
- 找到游戏主程序 Stalker2\Binaries\Win64\Stalker2-Win64-Shipping.exe
- 右键 → 属性 → 兼容性 → 勾选 禁用全屏优化
- 同一页点 更改高 DPI 设置 → 勾选 替代高 DPI 缩放行为（应用程序）
- 顺手关掉 Windows 游戏模式与 Xbox Game Bar 的后台录制，再复测一次
桌面鼠标就发飘的，先把 提高指针精确度 关掉；只在游戏里发飘的，重点查全屏优化和 DPI 缩放。Windows 10 22H2 与 Windows 11 23H2 上这两项都默认开着。

方法4 换 USB 口并排除鼠标驱动与回报率干扰
前置 USB 口、USB Hub 和扩展坞都会让轮询变慢，鼠标厂商的高回报率软件也会放大输入延迟。先把鼠标插到主板后置 USB 口，这一换常常就见效。
操作步骤
- 把鼠标插到主板后置 USB 口，避开前面板、USB Hub 和扩展坞
- 退出鼠标厂商的宏、灯光、高回报率驱动软件，任务管理器 → 启动 里一并禁用
- 把鼠标回报率从 1000Hz 降到 500Hz 或 125Hz 复测
- 临时拔掉采集卡、读卡器等占用轮询的外设
- 无线鼠标换新电池，接收器别贴着机箱金属面，尽量插到后置口
换口后如果手感立刻变跟手，问题就在接口或 Hub；仍旧延迟就查回报率设置；偶尔一顿一顿的，多半是宏软件在后台抢输入。

方法5 校验游戏文件并清理输入组件异常
游戏文件损坏或运行环境组件缺失，同样会表现成鼠标延迟、转视角卡手，改过 Input.ini 之后更容易出问题。先校验文件，再检查后台有没有别的东西抢输入。
操作步骤
- Steam → 库 → 右键游戏 → 属性 → 已安装文件 → 验证游戏文件的完整性
- Epic：库 → 三个点 → 管理 → 验证；XGP 走 Xbox 应用 → 管理 → 修复或重置
- 删掉被改坏的 Input.ini，让游戏重建一份默认配置再测
- 检查是否有第三方输入法、宏工具常驻抢输入，先退出再进游戏
- 用工具检查游戏运行环境缺失组件并修复，排除输入组件异常
- 若启动报 0x0000007B 一类错误，先回滚最近一次更新的显卡驱动
0x0000007B 多出现在刚更新完驱动之后，在设备管理器里回滚显卡驱动再启动，比反复重装游戏省时间。校验完文件记得重新进一次主菜单，让设置重新写入。
常见问题
《潜行者2》鼠标延迟只调灵敏度有用吗？
通常不够。游戏内的平滑与视角加速开关不关，Input.ini 里 bEnableMouseSmoothing 还是 True，手感照样发飘，先把这两处处理掉再看灵敏度。
潜行者2 XGP 版 Input.ini 路径在哪，和 Steam 版一样吗？
不一样。Steam 和 Epic 版在 C:\Users\你的用户名\AppData\Local\Stalker2\Saved\Config\Windows\Input.ini，XGP / WinGDK 版在 %localappdata%\Stalker2\Saved\Config\WinGDK\Input.ini，两处都要先开 隐藏的项目 才看得到。
改了 Input.ini 游戏进不去、启动报 0x0000007B 怎么办？
先把备份 Input.ini.bak 改回原名覆盖回去，恢复默认配置再进游戏。0x0000007B 多数和存储控制器驱动有关，在设备管理器里回滚最近更新的显卡或芯片组驱动后重启。
禁用全屏优化后还是发飘，是不是鼠标回报率的问题？
有可能。把回报率从 1000Hz 降到 500Hz 或 125Hz 复测，同时退出鼠标厂商的宏与灯光软件；如果换成后置 USB 口就正常，说明问题在接口或 Hub。
潜行者2 垂直水平灵敏度不一致、压枪跟不住人怎么办？
先把水平与垂直灵敏度设成同一数值，再确认 Input.ini 里关闭了平滑与加速。游戏本身的垂直水平比例存在偏差，只能靠小幅微调数值贴近，等后续补丁调整。
