I have very badly recognizable edges in fortnite that are very pixelated when I have anti-aliasing on low. If I set it to high, which makes it fairly easy to play, I only have 50 to 90 fps.
I have a 144hz 1080p (full hd) monitor. A ryzen 5 2600 and an RX Vega 64.
If I watch tests on youtube with this card, people sometimes have 200 to 400 fps. The graphics settings are all low except for the viewing distance.
I really don't know what to do anymore and have not found any contribution on the internet, maybe someone here knows more.
Try to reinstall the graphics driver, maybe something has changed.
And see if you have these additional programs from AMD. This recognizes games and then "optimizes" them automatically… Maybe this program has changed something and overwrites the settings in the game.
I have already done both, but thank you.
You can also run the "HWMonitor" program while gaming, which then shows you which components are running at the limit. + it shows you whether a component is too hot (and therefore clocked down → loss of performance.)
Which power supply unit have you installed?
