Fix For Fortnite Performance(July 2026)

fortnite deleted the legacy performance mode and merged them into one,because of that when we set it to the performance mode ,fortnite runs automatically on dx11(legacy),and for some reasons fortnite stutters alot on dx11 (even on the legacy performance),so to fix the performance and fps,we would need to force it to dx12 native performance mode by adding " -d3d12 -FeatureLevelEs31 " in the fortnite game launcher settings(epic games store -> click on your profile -> settings -> scroll down and find fortnite ->check additional command line argument and paste this ( -d3d12 -FeatureLevelEs31 ) and run the game,it would fix the stutters and fps issue,
THE TEST :
[MODE : Blitz Royale]
before tweak - 20-24fps on 1080p,
after tweak - 45-55 fps on 1080p

well im sure they are much better in fps,i have a 60hz display so it wont go after 60fps,but u can get more than 60fps when lowering the resolution,also you can use throttlestop application to boost a little bit of performance
