Depends on the game. Some run better on Windows, some on Wine. You need to check for specific titles with this kind of question.
I've seen multiple sources claiming that CoD2 and WoW run with better FPS on Wine for example.

Any software that is around 15 years or older has a really good chance of running, I would say even more than Windows 10.
Newer DirectX 9 games, specially with the wine-staging patches, have a good chance of running, but nowhere near what current Windows can attain.
Anything newer with DirectX 10, 11 or 12 is pretty much a train-wreck. Unless the game runs OpenGL or Vulkan, like DOOM 2016, which after removing the DRM and some patching from devs runs like a dream.
Unless you run wine with the gallium-nine patches (which implements DirectX 9, 10, and parts of 11 natively on top of the gallium driver system, providing native DirectX performance on AMD and the open source nvidia drivers).
Sadly, the wine maintainers prefer their ugly hacks for their DirectX implementation, so it’ll likely never be merged.

Also before it changed its name for the current retro acronym WINE used to mean WINdows Emulator: http://www.faqs.org/faqs/windows-emulation/wine-faq/
However, Wine is not an emulator in any way like the way that word is used in technology.
