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

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 change
• user.cfg, Limiting to 8 cores / 16 threads (performance cores only) → no change
• user.cfg, Limiting to 4 cores / 8 threads → no change, except a ~60% FPS drop

I’ve also tried the following with no improvement:

• Undervolting the CPU
• Updating BIOS
• Using Intel default power settings in BIOS
• Adjusting Windows power plans

To 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 far
• Whether 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.
