Horrible Multiplayer Lag

Ever since the most recent hotfix, the lag in multiplayer has been awful. I don’t know what changed, but the already spotty SHiFT ‘networking’ they have to cross play with steam players has been so unbelievably laggy. My friend and I believe it has something to do with particle effects from grenades, but there are so many spikes in ping throughout playing that its almost unplayable. I’ve asked other friends who play with other people and they are experiencing similar circumstances. My friend and I will both time-skip, enemies will teleport, and bullets wont hit their mark. I’ve already done network testing on my own end just to see if its my internet. I have a GTX 2080 SC, Ryzen 5 3600X, 32 gigs RAM and the game is loaded on an SSD so I am at a loss as to why it is so horribly laggy.
