Is anyone else experiencing a significant drop in internet download/upload speeds when launching Battlefield 6? I can run a speed test right before launching the game with 600+mb DL/UL, but when I launch the game it dips to 8mb download 6 mb upload. Ping and Packet Loss is equally terrible. I'm getting shot/dying behind cover. dumping whole magazines into enemies only to die to single shots by them. Any help/fix would be appreciated
GimmeUR1stBorn please download HWiNFO and post a screenshot of your System Summary.
OskooI_007 Hi, I'm having the same issue. Internet speed to only my PC drops to 10% of what it was before launching BF6. Other devices on wifi are not affected.
cody34562 Hi, I noticed in your HWiNFO screenshot that XMP memory overclocking isn't enabled in your motherboard BIOS settings. The memory is running at 2400MHz instead of 3200MHz.
If that doesn't fix your lag then please post an in-game screenshot with the network performance graph on-screen.

OskooI_007 I have the same problem, normal internet speed >500/500mb/s but when I lunch the game it's like 10mb download and 0,5mb upload, what should I do, I changed the router, changed EEE and green ethernet on ethernet card and others, nothing works
Patryk2k1 are you running a speed test while BF6 is running?
Yes, while bf6 is running I have 10mb/s download and 0,5mb/s upload on my laptop but when I do speedtest on the phone the internet is fine (500/500)
I have good ping, everything is fine within the game but discord has a huge packet loss
Patryk2k1 interesting. I don't know what's causing slower network speed when BF6 is running.
Patryk2k1 There are a number of things that could be at play here
CPU saturation from decompression/processing: Battlefield downloads and streams compressed assets. If your CPU is busy decompressing or handling game threads, it can starve the networking stack. Speedtest then reports artificially low speeds because the CPU can’t keep up with packet handling.
Turbo Boost / PBO instability: enabling Turbo Boost or Precision Boost Overdrive can cause voltage/frequency oscillations. That instability can slow down decompression threads and even affect NIC (network interface card) driver scheduling, making Speedtest results nosedive.
I noticed in the screenshot you posted to OskooI_007 that Turbo was enabled. That could be a potential factor and would be worth turning off in the bios and testing speeds again.
Network stack contention: Battlefield 6 may open multiple connections for telemetry, matchmaking, or background updates. These can interfere with Speedtest’s sockets, reducing available bandwidth for the test.
I think we can eliminate Network stack contention as Speedtest.net's sockets require TCP port 8080 to be open for outbound connections to function correctly. To my knowledge BF6 does not utilize TCP port 8080
Disk I/O bottleneck: Speedtest writes temporary data to disk. If Battlefield is simultaneously streaming assets to your SSD/HDD, disk contention can slow Speedtest’s ability to measure throughput.
Update
My own testing as follows
From bottom to top speed tests ran in the following order: No BF6, BF6 Splash Screen, Loading Shaders/menu and Conquest Match
There is around a 90% drop in DL and 54% in upload speeds from No BF6 to in game
