Title's self explanatory. Maps like Stryde-sniper when played in DM does not lag even if a high count of players while playing the same map in TDM / COOP will begin to lag almost immediately with 2-4 players.
Playing other maps in COOP that does not utilise TDM skins like EGRW does not lag.
Is this a bug or this is just how the game works. Or is it an issue with my side?
