We're pretty much on the same page 👍. I too question the logic of using the T-DFB that way as I think the steering column isn't the right place for certain effects, but I do think it can be done for pc games and could possibly add something for people that prefer different things (the personal preference bit we both agree on). Using SimVibe (or similar) you're running straight off the games physics engine just like FFB so there's no reason why it wouldn't add, but ButtKickers (or similar) IMO are the prime example of adding the feel to where it should be... seat of the pants.All those things you're feeling are just from the base FFB. Trust me, I've compared driving with the T-DFB on or off multiple times for a few months and decided with it turned off because it adds precisely zero info to my driving than just a constant rumble. Try driving without it for a month or so (to get used to the lack of rumble). You'll still be able to feel understeer/oversteer/weight transfer, maybe even better than before If you don't like it, then you can always turn it on again.
My understanding is that any effect that is not tied to the physics = canned. Fair enough I didn't use the word canned before this, but I was saying for a few posts before that it's not tied to the physics.
I don't know if you've played ISImotor sims, but they have 4 levels of FFB settings (Low, Med, High, Full). Most people don't know and just assume more is better, so they put it in Full (including me when I first started). But actually, all the info you need to assess car behaviour is already there in Low (tyre grip + steering rack forces). Med/High/Full just adds various "artificial" rumble effects like kerbs, brake/engine vibration.
Julien Regnard v1.0 Disclaimer (a tradition as soon as it deals with hardware): I assume no responsibility for any damage. Don't forget that the energy you spend turning the wheel always end mostly as friction heat and gears ageing. Too strong and jerky FFB will shorten the life of your wheel...simracing.fandom.com
I do know AC/ACC also has settings for extra effects (like the Enhanced Understeer and the road feel slider). I have all of them turned off, because I just like the purest FFB from the tyres and steering rack. In real life you get all these other sensations from your butt and the car's vertical movement, not from the steering wheel. Some people like to add in these forces to their wheel to compensate, but for me I drive just fine without it and consider it more a hindrance. If we ever get to the point that motion rigs become cheap enough for home use, then I might reconsider. But at the moment I'm happy enough without it.
At the end of the day it's personal preference as you said But I'm just questioning jad's logic of using the T-GT's signals to try add tactile immersion when there are far easier ways to do so (and even if you can get it to work, IMHO it won't help him feel the car any better). And also wanting to use it in PC sims when they are already superior in FFB even without it.
Good video on the topic if you have some time to spend (made by the guy behind Automobilista's physics). Summary from 42.00 onwards and discussion about bumps from 45.30.
Side note: I love the feel/kick of gear changes going through my seat with the ButtKicker
