# Top runs: * **Highest FPS**: `proton-cachyos` and `proton-cachyos-ntsync` both stand out with closely matched highest average FPS values. * **Smoothest FPS**: `proton-cachyos` offers the smoothest experience with the lowest standard deviation and variance in FPS. * **Best overall**: `proton-cachyos` is considered the best overall due to its combination of high FPS and smooth performance. # Issues: * The `proton-ge-921` run did not share the same OS environment (Steam Runtime 3 vs CachyOS) as the others, which may affect direct performance comparison. However, it still managed to perform well in FPS metrics. # Summary This benchmark evaluates the performance of "Doom Eternal" across different Proton versions (`proton-cachyos`, `proton-cachyos-ntsync`, and `proton-ge-9.21`) on an AMD Radeon RX 7900 XT GPU paired with an AMD Ryzen 5 1600X CPU. Both `proton-cachyos` and `proton-cachyos-ntsync` offer almost identical high FPS, but `proton-cachyos` stands out for offering a smoother performance with lower frame variance. The `proton-ge-9.21` version, although running on a different OS environment, demonstrated competitive FPS output yet with slightly higher variability compared to the others. Overall, the `proton-cachyos` delivers the best combination of high and stable FPS, making it the most effective choice amongst the options tested.
