I recently replaced Windows with Bazzite on my main gaming PC and so far I really like it. The system has a Ryzen 5 5600, an RTX 3060 12GB, 16GB of RAM, and a 4K 60Hz display. I usually play at 1440p or 4K on medium-to-high settings and aim for roughly 60 FPS.
Some friends told me that Nvidia hardware can lose around 5–10% performance on Linux compared with Windows when using Proton. Is that still generally true with current Nvidia drivers and Proton, especially for an RTX 3060? I know performance varies by game, but I'm wondering whether I should expect a noticeable difference overall.
Bazzite has been running well, and I'm tired of dealing with Windows, so I'd prefer to stay with Linux if the performance gap is minor. I'm also curious whether a gaming-focused distribution such as CachyOS would offer any meaningful improvement over Bazzite, or whether the results mostly come down to the individual game, driver, and Proton version.

Changing distributions usually won’t produce a magical performance boost. Bazzite, CachyOS, and similar gaming-focused systems can provide useful defaults, newer kernels, drivers, or performance tweaks, but the game and graphics stack are still the biggest factors. CachyOS may improve results in some setups, but it can also introduce different compatibility issues, so switching is mainly worthwhile if you have a specific problem to solve.
The biggest difference is often game compatibility rather than average FPS. Some games are nearly identical across both systems, while others have missing anti-cheat support, stuttering, or much lower performance. For a 4K/60 setup, a small percentage difference is unlikely to matter in most games, but it’s worth checking each title before assuming everything will work perfectly.
I’m using an RTX 3060 12GB and, in the games I play, performance is basically comparable to Windows. Nvidia support has improved a lot. I’d keep Bazzite for now and test your regular games with an FPS counter and frame-time graph before changing distributions.
There isn’t one universal performance penalty. Some games run a little slower on Linux, some are about the same, and a few can actually run better. With an RTX 3060, many games should perform close enough to Windows that you probably won’t notice the difference, especially when targeting 60 FPS. Check benchmarks for the specific games you play rather than assuming a fixed 5–10% loss.
The 5–10% figure can happen, but it isn’t typical for every title. Game engines, shader compilation, driver versions, and Proton compatibility all matter. A game that runs well can have smooth frame pacing even if its average FPS is slightly lower, while another title may perform dramatically worse or fail to launch at all.
