For playing Fortnite, it is generally recommended to set Jumbo Frames (jumbo packet) to Disabled or 4088. Most gaming environments, including Fortnite, do not require Jumbo Frames, and using standard Ethernet frames (up to 1500 bytes) is usually sufficient and recommended for better compatibility and performance with online gaming.
Setting Jumbo Frames to 9014 can lead to issues with packet fragmentation in some networks that do not support it, potentially increasing latency or causing connection problems.
In summary, for optimal performance in Fortnite, it is best to keep Jumbo Frames disabled or set to 4088 if you specifically know your network supports that size without causing issues.
