I play on PC, bought the phantom edition on steam for BF6 and played the beta. In the Beta, my game was genuinely unplayable. the constant frame drops and audio tearing made me try everything I could find online about how to fix it and nothing did. now that the game is officially out, I booted it up and it was completely fine (100+ fps no lag nothing) until about 30 minutes in game when boom. instant frame drops, audio tearing, CPU usage at 100%. I cannot find a single fix and I'm starting to wonder if I'm the only one dealing with this issue. CM title edit

Hey,Personally, it's the opposite for me. During the beta, I didn't have any problems. My game worked perfectly, everything was very smooth (I'm also on PC, I got the Phantom edition on the EA app). But in the final version of the game, even the menu isn't smooth. My PC is having performance issues, even though I had no problems during the beta. I don't understand.

Update: Enabled A-XMP in bios, seems to have fixed the issue but I only loaded onto a conquest briefly. Will update later tonight. Just finished playing my first few matches and the packet loss and lag is insane, GPU is barely breaking 75% but my CPU is between 85 and 100 the whole game. Frames aren’t an issue but packet loss and connectivity due to CPU stress is killing me. Is anyone else experiencing anything similar? Does anyone have a solution? It’s almost unplayable and gets worse on bigger maps with more people. I’d like to think it’s not my internet as I play every other game just fine.Ryzen 5 3600XAMD Radeon RX 5700XT

Same here, after playing for like 10 minutes in the same map, it starts lagging hard. EA plz fix this!

The game runs on 100% on all cores and i had 0 issues before on the beta. This introduces heavy performance problems and nothing on the side is usablei5 13600k (MB is updated to the latest BIOS), 4070 Super. EA pro version PC, win11, nvidia 581.15 i checked all heavy CPU marked settings and lowered and no result, the game already sits on 40% just in menue. Sure i can update the gpu driver, but it should not affect this, at least it would be crazy and weird.Of course all the secure boot stuff is running (because i played the beta fine before as i said) Before someone comes and says get a x3d... don't have anything to do with it! There is something not running correctly, or they changed the specs to crazy things but I doubt that.If more details are required, pls ask for it!

Hey everyone,I’ve been seeing a lot of reports about extremely high CPU usage and overheating issues affecting certain CPUs while playing. I’ve been trying to spot a pattern, but so far it seems to occur across many setups — especially with CPUs that have 8 or more cores.Some players have attempted to fix this by creating a “user.cfg” file with their core and thread counts (you can find guides on YouTube or Google by searching “BF6 CPU issues”). However, for many users, this method doesn’t seem to help — even when matching their system’s exact core/thread configuration or limiting the game to fewer cores.For example, on my i9-12900K:user.cfg, Using all cores/threads → no changeuser.cfg, Limiting to 8 cores / 16 threads (performance cores only) → no changeuser.cfg, Limiting to 4 cores / 8 threads → no change, except a ~60% FPS dropI’ve also tried the following with no improvement:Undervolting the CPUUpdating BIOSUsing Intel default power settings in BIOSAdjusting Windows power plansTo rule out cooling issues, I ran several demanding CPU benchmarks — none of them reached the same temperature spikes I get in-game.Interestingly, some users reported this issue starting during the beta, while others (like me) only began seeing it after launch.If you’re facing similar problems, please post your specs and list:What you’ve tried so farWhether anything helped (and how)I’ll compile all the information from this thread and, if needed, send a detailed report to the devs.Thanks for helping track this down.— A long-time Battlefield fan who hasn’t been able to play since release due to this issue.

BF6 Hitting 100% CPU Usage Causing Lag/Stutter/Latency/Slo-Mo Issues

I will try to find that, I will look and see what gear ratio does. Why did you go this way about fixing this?

not only when I die, but when I shoot, if I stand in the corner then it's better

I fixed the issue on my end, my 11900k would sit at 100% and I got 50-70fps, in my BIOS I changed gear ratio from 2 to 1,
now I get 160fps and CPU usage sits at 70%.

It doesn’t work, tried. Whatever is assigned gets overheated.

No the benchmark I use uses AVX2 instructions and it doesn’t overheat my cpu like bf6 does.

Here's a fix that worked for me. I had 100% CPU usage and was getting 50-70fps on 11900K,
I went into BIOS and changed the gear ratio from 2 to 1 and this fixed it.
now I get 160fps and my CPU usage sits at 70%.
Hope this helps anyone out there.

Samsung Galaxy Book 3 Ultra
Intel Core i7-13700H (6 performance cores / 12 performance threads + 8 efficient cores/threads)
NVIDIA GeForce RTX 4050 Mobile
I tried:
- low settings for all
- user.cfg for processor threads
- reinstalled game
- nVidia Profile Inspector
- turned off efficient cores through Process Lasso (set affinity)
When I launch the game, I get about 60-80 FPS from CPU and 80-120 FPS from GPU and low latency.
But somewhere around 20-30-60 seconds after launching the game, 4 efficient CPU cores are fully loaded, and CPU FPS drops to 20-40, and latency increases extremely, causing the entire game be like a jello.

Battlefield 6 launched, in the main menu
- 12 perfomance threads circled in red
- 8 efficient threads circled in green
- CPU utilization 30%
- threads loaded (effective clock on all threads) more or less evenly

Multiplayer started
- 12 perfomance threads circled in red
- 8 efficient threads circled in green
- 4 loaded efficient threads circled in orange, effective clock only on them
- orange arrows is the moment when after 20-30-60 seconds of playing CPU threads started loaded fully
- 4 other efficient threads circled in purple went on parking (!), completly 0 load
This means there could be three problems:
- either Windows can't properly distribute load between CPU threads for Battlefield 6
- or the problem is with Intel Core (wait for a processor driver update ???)
- or the problem is with Battlefield 6 (wait for a game patch ???)
IDK how I can fully turn off efficient threads, maybe it would be a solution...
BTW, the temperature of the processor cores during the game is approximately 60-70 degrees Celsius. So it's not a throttling issue.

P.S. Pls check the load on CPU threads during the game.
P.S.2 I checked in Community servers - the same. So it's not about ping, not RAM leakage... it's CPU leakage...

Thank you so much. Have been searching for a solution for days. Enabling A-XMP in the bios fixed it for me.

Description
While playing Battlefield 6 (Build 20199710) on a Ryzen 9 9950X3D, the CPU load is heavily pinned to the CCD without 3D V-Cache.
The scheduler does not seem to distribute threads to the V-Cache-enabled CCD, resulting in lower and unstable frame rates.
Environment
- OS: Windows 11 Pro 24H2
- CPU: AMD Ryzen 9 9950X3D
- GPU: NVIDIA GeForce RTX 4080 (Driver 32.0.15.8142, 2025/09/22)
- RAM: G.Skill Trident Z5 RGB F5-6000J3238F16GX2-TZ5RW
- Motherboard: Gigabyte X870E Aorus Pro Ice
- Game build: 20199710
- DirectX version: DirectX 12
- Resolution: 3840x2160 / Low settings
Observed behavior
CPU usage is concentrated on the CCD without 3D V-Cache.
Frame rate drops occur compared to other DX12 titles which correctly utilize the 3D V-Cache CCD.
