ive been having this problem for a while now, already reinstalled my pc, got a new router, ppl don't see me spike, when i spectate people they look smooth, no ping spikes whatsoever.

my net is stable too:
when i play other servers i don't have this problem at all, clipped some gameplay on another server and it looked smooth.
it's not just 1 or 2 players that look like this on fgunz for me, its literally everyone, it's like the dash animation just doesn't appear, makes the game unplayable, can't aim anyone
