# Top runs: * **Highest FPS**: `scx_lavd` with a mean FPS approximately 1% higher than the next best run. * **Smoothest FPS**: `scx_bpfland` with the lowest standard deviation and variance of FPS values. * **Best overall**: `scx_lavd` due to its highest mean FPS and comparable stability with the smoothest run. # Issues: * The `scx_lavd` configuration had the highest CPU temperatures, approximately 5% higher than other runs, suggesting a potential issue with thermal management. # Summary The benchmark compares the performance of the Steam Deck 512 LCD running Forza Horizon 5 using different scheduling configurations within the `sched_ext` framework against the default BORE configuration. Four configurations were tested: BORE, `scx_bpfland`, `scx_lavd`, and `scx_rusty`. Notably, `scx_lavd` achieved the highest average FPS while maintaining competitive stability, making it the best overall performer. The `scx_bpfland` configuration recorded the least variability in FPS, indicating the smoothest performance. However, thermal management under `scx_lavd` showed higher CPU temperatures, which could impact long-term reliability. Overall, the benchmark highlights the potential of `sched_ext` configurations to enhance gaming performance on the Steam Deck, with particular success seen in `scx_lavd`.
