[PC] MUT 26 Online Stutter at Fixed Interval (~2s) – Likely Sync Issue?

I’m trying to figure out if anyone else on PC is dealing with this because at this point I’ve ruled out just about everything on my end.

Whenever I play MUT 26 online (Head-to-Head or Draft), I get a consistent stutter roughly every 2 seconds. It’s not random lag—it’s like a rhythmic freeze/hitch that happens over and over, making the game completely unplayable.

What’s strange is that:

Solo challenges and all CPU modes run perfectly smooth
No FPS drops during the stutter (frame rate stays stable)
No packet loss or latency warnings show up in-game
Happens every single online match, regardless of opponent

Troubleshooting I’ve already done:

Wired Ethernet connection (stable, no issues in other games)
Updated GPU drivers to latest
Rolled back GPU drivers to a known stable version (12/18/2025)
Disabled on-field visual feedback (community suggestion)
Capped FPS to 120 and switched to borderless windowed
Cleared DirectX shader cache
Fully reinstalled the game

System specs:

i7-14700K
RTX 3080
64GB DDR5 (6600 MT/s)
NVMe SSD
Windows fully updated

At this point, it really feels like something tied to online synchronization or netcode rather than a performance issue. The fact that the stutter is happening at a consistent interval (~every 2 seconds) makes me think it’s not typical lag.

I also don’t have this issue in any other online game, so it seems specific to Madden/MUT online modes.

Has anyone else run into this? If so:
