Nvidia drivers have never been a mixed bag when it comes to performance or stability, they only lag in feature support for things such as Wayland compared to upstream drivers like AMD's or Intel's. Being an out-of-tree driver also means that your distro must give special support to it.
Performance will depend on the title, there will be some 5-10% average loss in performance for titles running in DXVK (DirectX to Vulkan translation layer). Vulkan titles should see no difference, and Doom famously runs better under Wine than natively.
The biggest problem with Linux gaming with Wine nowadays is just lack of support for games that depend on rootkits or other such malware to run, like some forms of client-side anticheat that run in-kernel, but there's been a lot of progress in that front. You might've seen the Roblox news that hit front page a couple of days ago IIRC; and some people have been able to temporarily get anti-cheats like EAC to run, until an update changes something and the pile of hacks fall apart.
