Found a possible fix for the abnormal TN value issue
After quite a bit of digging, I think I’ve finally found a solution for this strange TN value spike problem.
Coming from many years working at DELL, especially as L2 technical support for frontline engineers, I’ve picked up some “detective-style” troubleshooting habits.
After talking with several people across the forums and doing multiple rounds of testing, here’s what I’ve discovered:
🧩 The Fix (currently only confirmed on laptops):
Go into your BIOS or Windows settings and disable integrated graphics output.
For DELL gaming laptops, this setting is usually called “Hybrid Graphics” — disable it.
After doing this, the TN value may still fluctuate a little, but based on my own tests, it no longer spikes to the insane 400–1000 ms range.
On other laptop brands, you might need to check your BIOS options, system manual, or contact the manufacturer’s support team for how to fully disable the iGPU output.
🔬 Testing Summary:
I searched across Google and even consulted AI tools — no existing solution was documented.
I confirmed that changing CPU or power-related BIOS settings (like SpeedStep, C-States, etc.) actually makes the issue worse, which pointed toward a CPU-timing-related cause.
The problem never appears in offline modes, Portal private matches, or single-player campaigns — only in online multiplayer.
Multiple community members and streamers confirmed that desktop PCs do not have this problem, which made me suspect the integrated GPU (iGPU) layer specifically.
After disabling the iGPU via BIOS (this is preferable to just doing it in Windows), the issue improved dramatically.
Now my TN values range between 30–300 ms, typically hovering around 120 ms, and even during heavy moments (like many players clustered together) it might reach 400 ms — but at least the game is now playable.
💡 My theory:
I suspect there’s a regression or hidden logic in the Frostbite engine or the final release build of Battlefield that tries to access or sync with the integrated GPU when it’s present.
Since the iGPU isn’t actually handling the game’s rendering tasks, this unnecessary interaction could be causing the TN timing spikes.
This bug did not appear in the BF6 BETA, which makes me think some new or legacy code was reintroduced in the final packaged build that triggers the issue whenever a hybrid graphics configuration exists.
✅ Recommendation:
If you’re on a laptop and seeing abnormal TN values, try disabling the integrated graphics output and share your results here — it would be great to confirm this across different hardware setups.
do you have the nvidia app? try downgrading to driver version 577, i didnt have this issue in the beta aswell.
My iGPU is disabled from the start and still having the same issues. Im running Ryzen 7 7840H RTX4060 16gb ram still having the same issues.
Not gonna lie, I could not follow the majority of what you said.
But Im on a Lenovo Legion 5 so i decided to check, went into bios and I was already set to discrete graphics, decided to try the integrated graphics setting just to see what the difference was. The difference was a drop from ~80-100 fps to a solid 4 fps. Switched back real quick.
hopefully someone over at EA reads this and understands what youre saying because im getting really tired of community servers and CQB gamemodes.
After quite a bit of testing (both on my own system and through customer feedback), I think we’ve found one more piece of the puzzle regarding the TN value spikes / Time Smoothing instability many players have noticed.
🔍 What We Found
On lower-end CPUs (typically under 64 cores), the game runs smoothly — no TN spikes or timing issues.
On high-end CPUs, especially AMD systems or Intel CPUs with Turbo Boost enabled, the problem appears much more often.
When Turbo Boost (Intel) or Precision Boost / PBO (AMD) is disabled, the issue completely disappears.
I’ve confirmed this on several partner systems as well. We originally encountered similar timing problems during engineering simulations in ANSYS, and the same fix worked there too — disabling CPU boost features stabilized everything.
⚙ Possible Cause
It looks like Battlefield 6’s engine is very sensitive to CPU frequency fluctuations.
When Turbo Boost rapidly changes the clock speed, it can throw off the game’s internal timing or thread synchronization, which leads to the abnormal TN readings and stuttering.
✅ Workaround
If you notice the TN value climbing very high (100–1000 ms) while CPU and memory usage look normal:
Try disabling Turbo Boost (Intel) or Precision Boost / PBO (AMD) in your BIOS.
Restart the game and monitor the TN value again.
For me, and for several others I’ve spoken with, the TN value dropped to around 8–30 ms, and the stuttering was completely gone.
💬 Summary
Battlefield 6 seems stable on lower-core CPUs, but high-end processors may experience timing issues caused by Turbo Boost / Precision Boost.
If your TN values are spiking even with stable FPS and ping, try turning off CPU boost features — it might completely fix the problem.
This solution worked for me! But without turbo boost my config is getting like 30 fps so its unplayable either way☹️
