Put those settings on game and test your golf on Tsukuba, then put amateur and rerun. I'm not after big foot, those settings really matters.

I think your digging too deep looking for Bigfoot, or Bugs Bunnies "Secrete Stuff". You have a conclusion. "Rim choice impacts performance" now your trying to find facts to connect to your conclusion.

I'm trying to solve reason why others are unable to feel things and yes I solved reason now too. If that driving characterises is not on simulation game softens feedback and helps on front wheel guidance.
When testing make sure at all those settings are as on pictures, including sensitivity etc. (For that golf it's ok to use ABS as tune was intended to use it, I use it also when tested that golf)

I have it on Simulation already, I just don't feel it has an effect on the G27 I use. The only setting different is I have Power Steering set to "Off"..

I fail to see how wheel settings matter, are you saying the rims are no different if you use a DS3 but if you use a wheel with those settings and those settings alone a difference will emerge? I think if there is a difference in rims it would not matter the wheel or controller because there is a performance difference... So I should see a difference on a DS3 and any wheel any settings, not just a specific wheel with your specific configuration..


The mind is a very powerful thing... "I think therefore I am"

Quality normal?
Put that power steering on, for testing purposes it shows differences better than without it.
All settings identical.

And yes I know several things about thinking, and I'm not starting this blow on windmill without thinking first Smile

Possibly yes on another device with those settings, but altering settings are blurring FFB on G27, reason probably lack of power on ps3, and other things are made to mask sharp FFB out. So yes and no.
On ds3 you are playing anyway on different physics, game aids you anyway you want or not. Understand your ideology about "it should be same regardless what steering device is used" but it's not like that, there is differences. FFB should be same regardless of resolution, but it isn't, or even same resolution using different image "quality"setting, but it isn't.

Quality still on Sharpen, have not changed any settings of my wheel just yet as I don't have time to drive till later today.

Even if its true, I don't believe this will hide differences in rims. I simply feel there is no difference from one rim to the next.

No, the physics are the same

There is indeed an added steering assist, but still running the same physics.

Yes IMO it certainly is like that. If your saying there is a performance difference changing rims it should be the same difference no matter what controller or wheel you use, a different set up is a different set up.

I dont think my sharpen setting has anything to do with why I don't feel a difference between 2 things that IMO have no performance difference.

Drive over rumble strips, sharpen and those are smoother, on normal those are sharp. You feel rising on them and some of actual rumbles when on "sharpen" but on "normal" you feel whole rumble strip, rising, all rumbles, and coming down.

Ds3 and physics.. Well physics engine is same, but data sent to it is different. When you're able to point wheel precisely to direction where movement is you don't need much friction on it.

Do a barrel roll!
I tried Shelby 350 with Odes setup. I was using the normal rims and the pdi rims. I changed resolution 1080 ==> 720 and used normal image, but I didn't do any changes to the streering wheel. Time was same with both rims, difference was 0.04sec in Madrid. With this driving I tried to be strongly on Odes side, but I didn't saw any time difference.

@jouni are you using driving wheel or ds3 controller?
Did you test different sizes of PDI wheels? Test was intended to test different sizes of PDI wheels. Anyhow now you have reference point of stock size wheels, try with bigger PDI rims, +1" and +2".

Here's one Ridox replica as used on his club event.
Install "Golden Prodrive GC-010G" wheels on it and drive some hot laps, then install wheels on tune description..

After test is it going stable/oversteer/understeer with different wheels?

Tested that image sharpen bit, it increases grip of tires, smoother FFB - that smoothness is not "good", not worst of different FFB's what game can provide using different settings. Normal gives better FFB, more realistic grip and way how grip is loosed when on limits.

I was hoping to find something but IMO the lack of rim specs list in the SpeDB combined with a good understanding of how GT6 parts and settings codes work tell me there is just no difference, as much as I wanted to find one, I didn't. I also put the rim code list together decoding each set of rims, finding the code for all the off road wheels including unfinished set of rims not available in GTAuto.

If B-Spec Bob wasn't restricted to events and open for TT we could test it with Bob. GT4 Bob was good for that. He could mirror 2 laps if all settings Identical, any difference would produce a different lap.. It would of been nice for situations just like this...

@sinister, Jouni tested only between stock rim vs pdi +1", not as test was intended.
I'll stay patient and wait, maybe there will come a day... Smile
