Hello,
I get recurring desyncs in DayZ on several servers, official and community ones, but not on all of them. The game stutters and my character keeps walking forward as if the W key were stuck. It stops getting stuck when I press W again.
On 12 November 2026, I measured my network and my PC every second while playing on 195.82.158.67:10600, and logged 5 desyncs (Paris time, CET/UTC+1): 22:24:57, 22:54:31, 23:04:06, 23:31:00, 23:41:56.
What happens on my PC during a desync:
- DayZ's CPU usage drops sharply, from 10-16% to 4-8% of the whole CPU, about one core. The main game thread, normally at around 88% of a core, stops working and waits.
- GPU usage drops too, from 35-40% to 25-30%.
- No CPU core reaches 100%, and memory and video memory stay stable.
- In other words, the PC is not overloaded: the game has less work to do because it is waiting for data from the server.
What does not change during a desync:
- Ping to the server every 200 ms: 13 ms on average, 27 ms at worst, no packet loss in the desync windows.
- A second device on my network measured the same values at the same time, so my local network and router are not the cause.
- No errors on the network adapter (wired, 1 Gbit/s).
Setup: i9-12900KF, RTX 5070, 64 GB RAM. I stream with OBS at the same time; encoding runs on the GPU and stays steady at around 29% during the desyncs.
Since it happens on some servers and not others, and the client clearly waits for the server, could you tell me what could slow down the data sent to the client: server performance, DDoS protection or UDP relays, or a known issue with the current game version?
I can provide a CSV with one row per second around each desync (CPU, GPU, DayZ CPU usage, network throughput, ping).
Thanks in advance,
