GT7 Update – Polyphony Nerfs TrueForce and T-DFB (patch 1.49)

ByNeo Sphinx

It’s been a while since I’ve talked about Gran Turismo 7, although not that long — I recently did a comparison between T-DFB and TrueForce.
Today’s topic also involves TrueForce, but not for the best reason.

Recently, Polyphony Digital released a patch for GT7 that changes the physics and also affects the Logitech G Pro wheelbase in a big way — both for better and worse.

⚙️ Improved Physics in GT7

Let’s start with the good news.

Polyphony did an excellent job refining the driving physics. You can feel the difference in braking zones and during turn-in — the car behaves more naturally and progressively.

There’s a clearer sense of tire grip and weight transfer, and the overall control feels tighter and more believable.
In short, yes — the physics update was needed, and they got it right.

💪 Full Torque Unlocked on Logitech G Pro

Now to the next big change — and it’s a good one.

Before this update, the Logitech G Pro was capped at around 7–8 Nm of torque in GT7.
After the patch, you can now experience the full 11 Nm that the wheelbase can deliver.

This is how it always should have been — and finally, it’s here.

You’ll notice this especially with GT3 cars and high-downforce vehicles. The steering now has that extra punch through fast corners, curbs, and high-load transitions.

The result? A more violent, more immersive driving experience that better represents what this wheelbase is capable of.

💔 The Downside – TrueForce Feels Nerfed

Unfortunately, not everything improved.

The TrueForce feature — one of the defining aspects of the Logitech G Pro — has been significantly toned down.

Before the update:

  • You could feel engine revs,
  • The gearshifts had a satisfying jolt,
  • The wheel just felt alive.

After the update:

  • The rev vibrations are still there but much lighter,
  • The gearshift jolts are completely gone.

Even with all settings maxed out, and the firmware updated to the latest version, TrueForce no longer delivers the same rich feedback it used to.

It’s disappointing — not because realism is bad, but because GT7 is still a game meant for fun, and TrueForce added that extra spark of life that made driving more engaging.

Edit: While I didn’t verify it, users have also reported the same phenomenon for T-DFB, the haptic protocol of Thrustmaster and available on the T-GT.

🧠 A Possible Reason – Fanatec FullForce Incoming?

Now, here’s my theory.

We know that Fanatec is about to roll out its FullForce technology for GT7 — it’s already finished for iRacing, and GT7 will be the second title to support it.

Users on GTPlanet have reported that with their Fanatec DD+ or Extreme bases, they feel a big difference in force feedback behavior.

So, here’s the thought:

Maybe Polyphony toned down TrueForce intentionally to make FullForce look better by comparison.

I’m not saying there’s proof — but it would be a clever marketing move.
If the Logitech feels weaker after the patch, and Fanatec launches FullForce soon after, it’s not hard to imagine players being tempted to “upgrade.”

Edit Oktober 2025: After more than a year after this patch, there is still no sign of Fullforce for GT7. I consider this a piece of Vaporware from Fanatec.

⚖️ Final Thoughts

Overall, this GT7 update is a mixed bag.

✅ The physics are better — no doubt.
✅ The Logitech G Pro torque unlock is a great improvement.
❌ But nerfing TrueForce takes away some of the fun and character that made GT7 feel so special with that wheelbase.

Hopefully, Polyphony Digital will restore the full TrueForce experience in a future patch, or at least give players the choice to set their preferred intensity.
