Resxt IT WORKED!!!! THANK YOU SO MUCH!!

Xerxes I'm sorry, but where do I find this folder?

I wanted someone's help, I installed the normal game, it started and ran, but I wanted to increase the FPS but in this, I put "2X MSAA" and "FXAA" and I think something else and the game closed and crashed , and I think the error is in them, would it be possible for me to reset the settings?
