How to reset all graphics setting to default?

Last patch i manually changed texture_quality parameter in production_Config.ini file to 4. After i install Fall of Oriath all image on a screen become highly pixelated(like biiiiiig pixels). I tried to change texture quality parameter manually back to 0 or 1 = nothing changes. Same thing with usual method - Graphic Options inside PoE.
Could anyone share production_Config.ini file or told me how to set graphics back to normal?

Up?

delete the config file in ur documents/mygames/pathofexile
it will recreate after starting the game
