I was trying to get my game to run with higher fps, so I was messing around with the settings, but now my game won’t start. Is there a way to reset my settings to default?
You should always add some basic info to your issue, such as your OS, your graphics card, versions of gc driver, kernel and Lutris itself (native/flatpak), the title and Wine/Proton prefix used.
It’s also not entirely clear, what settings you’re talking about, your game’s or Lutris’.
Try to run Lutris in debug mode in a terminal and look for useful error output, i. e.:
lutris -d
