I tested character performance in a empty map using Performance Mode. It can’t even reach 200 FPS. However, when I respawn, so that the character wasn’t rendered, the FPS just went up to 300. I checked the latency stats. The game thread cost 7 ms, while GPU time is below 1 ms. Why is Fortnite character so CPU heavy? And I’d played some creative island PvP games with about 10 players, they can’t even reach 100 FPS.However, I tested similar scene with a playable character in UE5, it can run at 1000 FPS with DX11 backend (500 FPS in DX12).
