network spike and DC in maps with breach

it dosnt happen in boss areas or unique maps only normal maps that breach spawns in them(the wall clearing one) when you get close to the walls ping spikes to 7000-10000 then i get DCed, sometimes i manage to clear the breach before DC and the ping goes back to normal (50-60ms) fix this pls its unplayble,

Im having same issue. exactly the same. To add, i also have long load times into towns, but while progressing its fine.

Dont know if shader related, since it allways spikes at the same time
