Lagging only in battle royale mode

For some reason I will have a perfectly good connection, no lag spikes or anything, when playing arenas mode but the moment I switch to battle royale it's like my connection to the server is running off a potato. I have no clue why this is happening, my connection in other games I play is perfectly fine, and my connection when playing arenas mode is fine as well, it's only when I want to play battle royale that my connection sucks. Does anyone have any suggestions?
