Battlefield 6 broken lag / LAT DEV spikes

Hi, I’m on a wired gigabit connection with a Netgear Nighthawk router and everything else online runs perfectly.

 

In Battlefield 6 (PC, US-East), I’m getting severe LAT DEV (jitter) spikes even though my latency stays around 30-40 ms.

 

To rule out my setup, I ran:

• ping -t 8.8.8.8 — steady at ~20 ms with no spikes during in-game lag.

• Then pinged the game server IP (found via netstat -n | findstr 30000) — huge spikes 100–300 ms+ while gameplay stutters.

 

This clearly shows the problem is on the Battlefield server/routing side, not my ISP or hardware.

 

Many players are reporting identical behavior (stable ping, massive LAT DEV swings). Please escalate this to the network/server team.

Thanks for taking my original post down for absolutely no reason!:)

  • OskooI_007​ I think i have solved my issue. I kept the user.cfg file, I guess I understand what your saying, but my results with the custom file cut cpu usage in half across all cores, if I dont use the file it really runs at 95-100% causing a bottleneck. With that said, I switched my xmp profile to 2, found out my ryzen 5 5600g its only officially rated for ram speeds at 3200mhz, thats why when I enabled xmp it was defaulting to 3200mhz when I had it on auto. I switched that to 3733mhz which is what the ram is rated for. That also somehow fixed the issue with the incorrect timing of ram aswell. 

    Im not sure if this is also related but i believe it did help a lot, i had my main monitor plugged into my mobo hdmi slot instead of my GPU because with both my primary and secondary monitor plugged into my GPU, bf6 would load in with my resolution set wrong even when I had the correct settings in game. I opened up Nvidia control panel and forced the display to render on the GPU not display, and checked rhe box to override any game setting. I also set the 3d settings for ultra performance. After all that the game is actually running how it should, thank you for all your help.
