Hello. My PC isn’t that good performance wise. I am also very new to UE 4, and am still studying the way everything works, but there was one time when there was a popup saying that my FPS was under 20 FPS, and that it’ll make some changes to the graphics, and so I clicked on the “OK” button. That’s where my question is: HOW can I revert it back to normal again??? I have looked into the options and reverted everything back to default, but the game still looks too ■■■■■■, and I cant have a real look on how the game looks like, both in the editing mode and the play mode… Also, it did the same on pretty much every other project that i’ve made… Anyone knows how to revert it back to normal?
Thanks and have a good day 
Hi there.
The editors graphics settings can be found under Settings → Engine Scalability Settings:
The popup should only set this settings to lower values. Just increase them again and everything is back at normal.
Thanks a lot! Much appreciated. Have a good day! 
You’re welcome!
