Have you actually tried to run the Windows version of Factorio through Proton and experienced slowdowns? In my experience, WINE doesn't result in a noticeable slowdown compared to running on Windows natively (without "emulationware" as you call it), unless there are issues related to graphics API translation which is a separate topic.

I believe OP is referring to the fact Factorio has some optimization on Linux such as using fork() to autosave (which is copy-on-write unlike its Windows counterpart), which result in zero-stuttering during auto-save for large-SPM bases.

I’m a huge fan of Wine, but there’s no reason to run Factorio under it. The native Linux version works flawlessly from my experience, and I’m even using a distro where problems with native binaries are common.

That says very little about whether there'd be a noticeable slowdown compared to running a Linux-native version on Linux natively, though.

But there almost always are problems in that area. I've never had a game run with the same FPS and stability in Wine vs natively in Windows.

My point was it's not inherent to WINE. There's a lot of Windows games which support Vulkan or OpenGL, those work excellently.

Csgo is OpenGL and doesn't work excellently in my experience, but yeah, in theory they should.

CS:GO is Direct3Dish with an OpenGL shim (or alternatively with a better Vulkan shim now).

Exactly the same fps, unlikely.

But phoronix has tons of benchmarks showing that WINE/proton are in the same ballpark as the native windows version, sometimes a bit slower but as many times a bit faster as well.
