# Top runs: * **Highest FPS**: `Proton 9` reaches the highest average FPS, exceeding alternatives by more than 5%, providing a significant boost in performance. * **Smoothest FPS**: `Proton 10` offers the lowest standard deviation and variance in FPS, promising more consistent frame delivery over time. * **Best overall**: `Proton 10` achieves a strong balance with high average FPS while maintaining superior smoothness compared to other runs that offer higher FPS but less consistency. # Issues: * Proton versions on Steam Runtime consistently outperform CachyOS by a notable margin in FPS, suggesting a significant performance gap not driven by hardware differences. * While comparing Proton versions, the CachyOS setup experiences higher CPU and GPU temperatures and slightly elevated CPU load, which could impact thermal performance and efficiency over extended sessions. # Summary In this benchmark comparing different `Proton` and `Proton-cachyos` versions on `CachyOS` and `Steam Runtime`, the `Proton 9` on `Steam Runtime` achieved the highest FPS, demonstrating the superior performance of the Steam version. However, `Proton 10` on `Steam Runtime` offers the best balance with smooth performance and high FPS making it the best overall option. The `Proton-cachyos` versions lag behind, indicating a less optimized experience possibly attributed to software compatibility or configuration settings within their OS environment.
