Understanding Wheel Settings

[deaconw]

Moved this out of a previous thread to try and understand the game settings, specifically the degrees of rotation setting.

I have an old Xbox 360 wheel with only 240 degrees of physical rotation. The profiler correctly identified this when I did the wizard. Later I set it manually to 900 degrees based on a lot of advice on the interwebs, appareantly based on lots of 900 degree wheels. I then did some measurements to try and understand the setting. This is what happened. Car is a 1M S3. I just sat there in the pit and moved the wheel and recorded the virtual wheel position.

DoR = 240
Gamma = 1.0

Physical Wheel-------In game Steering Wheel
0 --------------------------0 (no surprise!)
90R------------------------300
120R----------------------450

OK, makes sense, game is scaling the 240 to 900 by a fixed factor so car must be a 900 car (I actually think it is a 1080, but lets not quibble)

Next
DoR = 900
Gamma = 1.0

Physical Wheel-------In game Steering Wheel
0 --------------------------0 (no surprise!)
90R------------------------300
120R----------------------450

So...the exact same.

So my request it...what exactly does the DoR setting in AC do? I have read people adjusting that setting to 720 (from 900) for drifting....but, based on my experiment, that had to be placebo effect. Or they were talking about the actual steering wheel app and doing a reduced scale mapping there. TIA.

A better place to post this would be the official AC forums

Considering your wheel is limited to 240 degrees. My guess its AC is applying some sort of multiplying factor to simulate 900 degrees of rotation. Which has to make driving at speed that much more difficult.

The (Degrees:) setting tells the game the physical limit of your wheel.

Do a setup and calibration in the game and see if the DOR is actually setting itself (automatically) to 900. (that of your wheel) My guess is that it is not, and cannot be recognized as 900. Not saying you can't get 1:1 with the virtual wheel.

A simple test- Make sure you have this set- C:\Program Files (x86)\Steam\SteamApps\common\assettocorsa\system\cfg -(assetto_corsa.ini)
[SOFT_LOCK]
ENABLED=0
Then- Set your Xbox wheel to 420 deg. (if you can) and set the game to 420 as well, then test drive the Ferrari 458 gt2 and see if the virtual wheel ia 1:1 with the xbox. If it is not then @Nakadai is probably right.

That appears to be the case from my test. Still makes the actual DoR setting in the game appear pointless.

If I do the calibration it sets it to 240. The wierd part I am trying to resolve is that it behaves the same no matter if DoR is set to 240 or 900...so I am trying to figure out what that setting is for.

To answer the question [what that setting is for]. It tells the game how far your wheel(controller) will turn lock-to-lock. You can use it in two ways, and it is governed by the [SOFT_LOCK] ENABLED=0 setting. One way to use DOR, as I do, is to set your controller to a specific Lock to match a specific car, and set the DOR to the same. This gives me correct Lock for that car and 1:1 ratio between virtual and real wheel. Another way to use it is to set [SOFT_LOCK] ENABLED=1 and set your controller to 900 deg. (or native max)(mine is 1080) and set the game to 40 DOR. (the game min). With this setup the game software will set the lock and animation for each car automatically.

Can you actually get the xbox to be recognized by windows as a 900 deg, controller? In game controllers test page- Does it physically turn 900 deg. lock to lock?

IF I understand you correctly, this only works if your physical controller has more DoR than the car you want to simulate. But yes, I think I understand it from that perspective. But it is really just putting a stop point via stop lock.

Interesting...I will have to try this.

No and No. Only turns 240 physically. What I would have actually liked is for it to only turn the steering wheel in any car only 240 degrees....would make tight turns hard but would be less twitchy to drive. But AC apparently maps the 0-max output of the wheel to the 0-max DoR of whatever in game car you are using (this makes sense), no matter what the DoR setting is...unless you are using softlock, as you mentioned. When my DGFT gets here this will all be moot, I suppose.

look into graphic options, there is something to limit the rotation of the visual steering wheel... with a 240° wheel you should set it to 120°...should be 1:1 with your physical wheel then.

Thx, I am aware of that, but I am focused on the physical-to-sim aspect, not appearance. Altering the visual simply makes the Sim lie to me...

The appearance of a 1:1 on screen wheel to your physical wheel is the correct physical-to-sim aspect- anything different and its wrong.

You really need a wheel with 900 degree rotation, you can't drive most cars with 240 degrees as thats not enough turning if you want proper 1:1 steering.

I agree...which is why I've ordered one. Still seems like the DoR slider in the settings is neer pointless because AC will scale the car steering to the output of whatever wheel you have. I'll experiment more when my new wheel gets here.

To fully understand the function of the Degrees slider- Realize that there are wheels with limits as high as 4500 deg. (Accuforce DD) and can be adjusted on-the-fly. My Clubsport V2 is able to do this as well. Not much has been said about this, but I believe that you have better FFB when you use the wheels manual Lock setting(in conjunction with the slider) instead of the games automatic Soft lock mode.

Also, If i use the [SOFT_LOCK] ENABLED=1 My wheel bounces of the stops instead of stopping dead.

I just read a similar post on the AC forums. This makes perfect sense. Thx. BTW, looked at the Accuforce stuff...wow...stg 5 costs more than my car did!)

Which wheel did you order?
