When i watch others when they play fortnite no matter if bad or good pcs the graphics looks very nice and for me but not it looks like playing on a lower resolution speaks on less pixels to my pc gtx 1080 the rest is too actually very good that doesn't matter anyway I don't know why
Screw the textures and post-prossesing at least to high.
Set your 3D graphics to 100% and anti-aliasing to low.
If your pc does it then the shadows on high.
And always consider distance to be epic.
Maybe it's on the monitor? What resolution does it have?
Yes no I have no problem with that. They have everything the same as I do in-game but it just looks different with them
1920 to 1080
