The overhead added by Proton, compared to the CPU time consumed by the actual game, is minimal. The greatest benefit is that you don’t have dozens of Windows services hogging half of your memory and CPU.
Some games have some quirks that can cause performance issues when running under Proton. Deathloop, for example, was good on Windows, but unplayable on Linux with the same hardware (Ryzen 5 2600, 16G RAM, RX 6750 XT). There was massive stuttering even on minimum graphics, and every level took several minutes to load. It works now, but since then I’ve upgraded to a 7800X3D, so I’m probably just brute-forcing my way through the same issues.
That completely depends on the game. Many play just as well if not better, some play worse or not at all. Check out a site called ProtonDB for a huge list of games and their level of playability.
Probably, but I’m already running ancient hardware and I tend to favor retro and indie games, so I’m not the best to ask about that. Some people do report better performance under Proton though. Windows has a lot of bloat that doesn’t exist with WINE/Proton running in Linux.
Are there ever any performance issues from proton compatibility?

It doesn’t get much better than Digital Foundry’s coverage on the matter.
Spoiler alert
Performance is about similar. So no significant performance issues.
