For Fortnite FPS drops, test the same place in the same match type, then confirm the PC meets Fortnite's requirements and verify the game files. Try Performance rendering mode, turn off high-resolution textures if you do not need them, close background apps, and update the graphics driver. Change one setting at a time so you can see what actually improves the frame rate.
Choose one place or replay where the frame rate drops and note the starting FPS. Test the same scene after each change. Network lag moves players late, while low FPS makes the whole picture update unevenly.

Check requirements and files
Compare the PC with Fortnite's current requirements. In Epic Games Launcher > Library, open Fortnite's menu, choose Manage, and select Verify. Wait for damaged or missing files to be repaired.
In Fortnite, open Settings > Video and change Rendering Mode to Performance - Lower Graphical Fidelity, apply the change, and restart the game. This reduces visual detail to help less powerful PCs.
4
Remove optional large textures
In Epic Games Launcher > Library, open Fortnite's menu > Options and clear High Resolution Textures if you do not need them. Epic says this saves storage and can reduce the amount of large texture data the PC handles.
5
Reduce background load
Close browsers, downloads, recording tools, and unnecessary launchers for one test. Install the current graphics driver and make sure the PC vents are clear, especially if FPS drops only after playing for a while.
6
Use the Windows performance settings
On a laptop or a PC with more than one graphics processor, set Fortnite to High performance in Settings > System > Display > Graphics. Epic also documents Game Mode, power, and Delivery Optimization settings for low FPS.
Return to the same scene and compare the FPS. If none of the changes help, restore settings you do not want and follow Epic's full low-frame-rate guide before replacing hardware.
If the frame rate starts high and falls as the PC becomes hot, clear blocked vents and stop the test if the device becomes unusually hot; do not open hardware you are not trained to service.
If the PC is below Fortnite's minimum requirements, settings may help only slightly. An unsupported processor, memory amount, or graphics adapter cannot be repaired by a launcher reinstall.
