Lag Spikes only during Hordes

Issue Description:
Lag spikes correlate with horde intensity; the higher amount of mobs generated, the higher the lag spike. High intensity missions in Damnation often cause disconnects.

Attempted Solutions:
Switching network bands has had no effect. It seems to be noticeably worse during high traffic times of day. Likely affected by packet loss.

Platform:
Steam

You are not alone there.
It got better after I complained to my ISP a lot one day.
And they also came to check the fiber and fixed some excessive signal issues on the fiber.

I have no idea what truly made these spikes happening every evening for 2 weeks to stop one day.

My lag spikes on horde leading to desyncs began after a patch amd lasted 2 weeks after, always on peak hours in the evening beginning at 6, so I was linking them to the agressive traffic shaping

Me complaining about their traffic shaping to the ISP hit a callcenter wall, but who knows if they changed something on my line after.
Or was it the jitter on the fiber they reduced.
Or if Fatshark chabges somethjng on their server close to me, or their routing or …

Try to contact your ISP and have them check your line if that is possible where you live., maybe ?

Let me add a correction : this is definitely Fatshark servers.

This just came back massively with the new patch.
