I didn’t realize you were new, it sounded like an issue anyone could have. Gaming on Linux is definitely not a perfect experience. Please don’t be afraid to ask around in the various linux_gaming communities, there are always people who are willing to help.

What’s your computer like? What brand and model is your GPU? What distribution? If the GPU is Nvidia, do you know if you have the open-source Nouveau or the proprietary Nvidia driver?

A bit of a glossary:

• Wine: a compatibility layer that allows Windows executables to run on Linux systems by translating Windows system calls to Linux calls.
• Proton: a derivative of Wine maintained by Valve, optimized for gaming on Steam.
• Wineprefix or prefix: a mock-up of a Windows filesystem. The application running inside Wine sees this as the C: drive. The default wineprefix is located in ~/.wine. The system’s root directory is mounted as the Z: drive.
• Lutris, Bottles, Heroic: graphical front-ends to manage many aspects of your Wine applications.
