SOTTR can now run in proton-experimental (it used to crash due to a missing vulkan feature), but how does it compare to the native version?

Normally I would just use the native version, but got the game from epic, which doesn't provide the native build. So if I wanted to run native I would have to acquire the game from other sources (keep in mind that I own the game on epic), which is less than ideal. But I wouldn't do it if there's no advantage.
