Kids and gentleman, it's time to clear up confusion;
The T-DFB feature you're all wondering about is not simply "vibration like you'd feel on a dual shock controller". I smiled when I read a comment claiming just that in a previous post. Its laughable to think that'd be the case. There are engineers at guillemot thrustmaster that get paid close to 6 figures researching and implementing technologies such as DFB.
Dumb acronym aside, DFB is additional hardware attached at the end of the base. It's that thing that looks like a giant puck. That's called a transducer. Sort of like a speaker, but primarily produces "vibration" rather than sound, especially in the low end frequency range.
What Thrustmaster have done already exists in sim racing to a certain extent. Sim Vibe software (sim commander 4) from Sim Experience, reads telemetry from PC racing sims and converts it to a proprietary audio signal that is meant to be sent to one, or a series of, transducers. Other names for these things are called butt kickers and bass shakers. They're as cheap as 30$ and as much as 500.
So essentially the telemetry from Gran Turismo is converted to a signal that is sent to the transducer on the back of the T-GT.
I'll be doing an episode of tech drive life on YouTube covering this in more detail. (Not the wheel, just the feature and why it's good).
If you have no idea what simvibe is, or what sim experience is, I'd highly recommend you check them out first and watch the tutorial videos to get a better idea of just how significant transducers are.
In short, they add incredible immersion to any sim racing setup. By a mile, it is the most significant jump in immersion that you can do for your setup if you're sim racing on PC.
So what thrustmaster have done is something similar, except it's all sort of built in, and the transducer is attached to the wheel. -which is fine, and here's why...
When I was tinkering with butt kickers and sim vibe (sim commander 4 software) on my old 8020 rig, I tried something new. I mounted the butt kicker that was originally near the floor on my rig, and switched it to right behind the wheel, on the center rail, but still out of the way so it didn't hit my legs.
The effects I used we're typical of the "seat" mode in sim vibe, (engine rpm, road bumps, gear shift clunks, etc) - except I added some additional effects, such as speed based white noise, and road texture, etc.
The results were incredible. The wheel felt like it was attached to something alive. Bare in mind, that effect was already felt throughout the rig, but it added something even MORE when it was felt throughout the steering wheel! It sort of tricks you into thinking you're getting the most advanced and detailed force feedback ever conceived. But in reality it's a unity between two different pieces of hardware, connected in perfect sync with software.
The coolest thing it did was it "masked" any notches or imperfections in the steering sensations, no matter what wheel. It masked the harsh spikey feedback from the osw when MMOs ran with low filter settings. It masked the notchy belt ridges that you can feel when turning the TS-PC. The effects felt through the wheel are what make you feel the illusion of smoothness. Once I discovered this little bit of knowledge, I always ran a buttkickers or bass shaker close to the wheel and programmed a proper preset in sim commander software.
Sorry to run on there, but the main point is, the transducer on the back of the T-GT is MUCH more than a glorified "rumble pack." I heard great impressions from those who have tried it with GT sport.
But since the DFB feature is only available when playing GT Sport, it's potential to be tweaked and explored by the end user in a PC sim is sadly lost unless thrustmaster decide to make that someday available, if it's even possible.
Thanks for the good explanation. Indeed it feels like a transducer with simvibe. Do you know if you can turn up the volume?
