Input buffer desync in online matches — server-side netcode issue Xbox Series X
Platform: Xbox Series X
Region: Europe (Poland)
Game mode: FUT / Rivals / Champions
Connection: Wired Ethernet, 1 Gbit FTTH, dedicated gaming router with QoS
Server: GCP Warsaw (europe-central2), confirmed via live telemetry
Issue:
In online matches, directional inputs are processed out of order by the server. Example: I input a forward pass, but the game registers my next input (stick direction change) before completing the first action, resulting in the player passing backward instead of forward. This is not input lag — the inputs arrive on time but are executed in wrong sequence.
This started after the April 1st update and affects every online match. Offline modes (Career, Kick-Off) work perfectly with zero delay.
Network diagnostics (measured during gameplay):
- RTT to EA gameplay server (GCP Warsaw): 14 ms
- Jitter: 0.089 ms (std dev, 300 samples)
- Packet loss: 0%
- Bufferbloat: -0.004 ms (effectively zero)
- LAN latency to console: 0.4 ms
- DSCP EF marking active, Voice queue priority, zero drops
These numbers confirm the issue is not on my network. Packets arrive at the server within 14 ms with sub-0.1 ms jitter. The input reordering happens server-side in the input prediction/buffer system.
Other players across all platforms report the same issue on EA Forums after the latest update.
Requested action:
- Investigate the input buffer/prediction engine changes introduced in the April 1st patch
- Check if server-side input queue ordering was modified
- Provide a fix or rollback the netcode changes
