# Downsides and Limitations of the Compatibility Layer

Unfortunately, compatibility layers are not perfect and do not support every Windows or DirectX call yet. While compatibility is quite mature and stable on Linux, it still rapidly improving on macOS. Some issues might be found, and some games might not work at all, although this is a small number. Some of these limitations include, but are not limited to:

1. **Performance Impact** Games running on Linux may experience up to a 10% performance decrease, while macOS users could see a reduction of up to 25%. On the other hand, some games might have better performance depending on how they were developed.
2. **Shader Lag** DX9/10/11 games might exhibit lag due to real-time shader caching. Once the shaders are cached, they persist until a game or driver update.
3. **Anti-Cheat Incompatibility** Kernel-level anti-cheat systems (e.g., Vanguard, Easy Anti-Cheat) suffer compatibility issues. While Easy Anti-Cheat and BattleEye offer support for compatibility layers, this must be enabled by game developers and requires a specific library file within the game folder to work on Linux. macOS support for these anti-cheat products is not yet available when using compatibility layers.
4. **Bugs and Glitches** Users may encounter bugs and glitches when some system or DirectX calls are not fully supported by the compatibility layer.
5. **Additional Workarounds** In some cases, installing additional Windows libraries (e.g., vcrun, dotnet) may be necessary to run certain games. On Mac and Linux, HyperPlay ships with Winetricks, making it easy to install these tools. An automated way to install these workarounds is planned for a future HyperPlay release.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.hyperplay.xyz/developer-docs/compatibility-layer/downsides-and-limitations-of-the-compatibility-layer.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
