 The following settings are available under the **Session Replay** section in the plugin settings:

-- **Replay duration (ms)** (`SessionReplayDurationMs`, default `5000`, range `1000`–`60000`) — The requested length of the retroactive replay window. On Windows and macOS this is the rolling clip length kept on disk for crash attachment; on Xbox it's the requested length of the OS-captured clip (which may be shorter if not enough frames are buffered). This value is ignored on Android, where the underlying SDK determines the duration.

 - **The `AVCodecsCore` and `NVCodecs` engine plugins must be enabled** in your project. The Sentry plugin only compiles the recorder when these are present.
-- **An NVIDIA GPU is required.** Encoding goes through NVIDIA NVENC; machines without a compatible NVIDIA GPU fall back to no recording (the feature self-disables and logs a warning).
+- **An NVIDIA GPU with a recent driver is required.** Encoding goes through NVIDIA NVENC; machines without a compatible NVIDIA GPU fall back to no recording (the feature self-disables and logs a warning). The engine's NVENC integration requires a minimum NVIDIA driver version of **531.61 on Windows** and **530.41 on Linux**. On Linux, the proprietary NVIDIA driver is required — NVENC isn't available with the open-source Nouveau driver.
 - **A plugin rebuild is required after toggling the setting.** Whether Session Replay is compiled in is decided at build time from `AttachSessionReplay`, so after enabling or disabling it, delete your project's `Binaries` and `Intermediate` directories and rebuild.

Any sensitive information shown on screen (player names, chat, email addresses, in-game purchases, and so on) will be present in the captured video. Only enable this feature if the content rendered by your game is safe to record, and make sure your data-handling and privacy policies account for it.
