I have seen native versions tank as the default distro setups change over the years. As weird as it sounds it feels more reliable to use the windows version under proton/wine. Often game modding communities stick to the windows version.
Once M$ inevitably introduces Windows Cloud with subscriptions and the lowest tier being ad supported with anti-adblock and a registration fee, then Linux will become the preferred experience native or otherwise.
For the time being though wine and proton are good enough. I have been doing all my gaming on the steam deck and there haven’t been any games that make me feel like it’s a lesser experience in any way. The few games I have any difficulty running tend to be shitty games with micro transactions and kernel anticheat that doesn’t even prevent cheaters. Several can be made to work anyways. You can even install poorly made games and mods using the case folding toggle in ext4 that steam deck does have access to.
I am admittedly still waiting for someone to tell me that Wayland incompatibilities are a thing of the past…
