This guide was inspired by multiple users who wrote similar guides with unnecessary and outdated information, they weren't complete or they were inaccurate. If any user notices any mistakes simply write a comment or if you're not comfortable doing so contact me on Discord at Thanasoles.

My goal is to make this guide as simple to follow and as accurate as possible, it's good to remember that we all make mistakes, even those who push to be perfect.

If this guide helped you it would be heavily appreciated if you liked, favorited or commented on it!

If you're feeling charitable feel free to give me some steam points ~ check below for how!

If you are still having FPS loss my suggestions would be to do the following:

1. Update your GPU drivers.
2. Go through each individual setting and turn it to low to see how much FPS you gain.
3. Reinstall your GPU drivers or back up to the previous version.
4. Verify integrity of files on Steam.
5. Reinstall the entire game.
