GT Legends (no grip info, no matter the firmware...)

byAGM

Hi there.

I only play GT Legends. Yes, there are classic cars in assetto and iracing, but not such a content mods and community like in GT Legends.

I bought SW20 v3 months ago and I still have to play with MMOS because although the support and wheel turning forces are very good, there is no information about the grip so its impossible to slide the car, and... with classic cars you need that information in your hands.

I have tried with Mmos, Fanat..., Logit g27, everyone works. It has to be something on the firmware... (I have tried 19.08.06 and 21.02.06).

I´ll try to upload a video because it can easily be seen (visually) on cobbled roads (there´s no vibration, like I was driving on a smooth surface).

Thanks.

Can you supply a car & track combination that most readily highlights this behaviour as well as your sim and desktop app settings?

Here you can see a visual comparison between MMOS and Sim-plicity:

Here you can download the track:

The car in the video its a R8 Gordini but you cant test it with any light car if you preffer. Its the same.

My UserData/User/User.plr ffb parameters are these:

FFB Device Type="1" // Type of FFB controller: 0=none 1=wheel, 2=stick/custom, 3=rumble pad.
FFB Effects Level="4" // Number of FFB effects to use: 0=No Effects, 1=Low, 2=Medium, 3=High, 4=Full, 5=Custom.
FFB Gain="0.71000" // Strength of Force Feedback effects.  Range 0.0 to 1.0.
FFB Throttle FX on steer axis="1" // 0 = Throttle effects on throttle axis, 1 = throttle effects on steering axis.
FFB Brake FX on steer axis="1" // 0 = Brake effects on brake axis, 1 = brake effects on steering axis.
FFB steer vibe freq mult="1.00000" // Controls frequency of steering vibration. Recommended: 0.5 to 1.0, 0.0 disables steering vibration.
FFB steer vibe zero magnitude="0.01000" // Magnitude of steering vibration at 0mph (reference point).
FFB steer vibe slope="0.00300" // Slope of line defining magnitude as a function of frequency (used with FFB steer vibe zero magnitude).
FFB steer vibe wave type="0" // Type of wave to use for vibe: 0=Sine, 1=Square, 2=Triangle, 3=Sawtooth up, 4=Sawtooth down.
FFB steer force average weight="1.00000" // How much weight is given to new steering force calculations each frame (0.01 - 1.0). Lower values will smooth out the steering force, but will also add latency.
FFB steer force exponent="1.00000" // Steering force output "sensitivity".  Range 0.0 to infinity.  0.0 to 1.0 = higher sensitivity, greater than 1.0 = lower sensitivity.
FFB steer force input max="11500.00000" // Recommended: 11500 (-11500 if controller pulls in the wrong direction).
FFB steer force output max="1.70000" // Maximum force output of steering force, recommendation 0.8 to 2.0
FFB steer force grip weight="0.80000" // Range 0.0 to 1.0, recommended: 0.4 to 0.9.  How much weight is given to tire grip when calculating steering force.
FFB steer force grip factor="0.60000" // Range 0.0 to 1.0, recommended: 0.2 to 0.6.  How much of a factor the front wheel grip is on the steering weight.
FFB steer update thresh="0.00000" // Amount of change required to update steer force/vibe (0.0 - 1.0). Lower values = steering force updated more frequently = lower frame rate.
FFB steer friction coefficient="0.10000" // Coefficient to use for steering friction.  Range: -1.0 to 1.0
FFB steer friction saturation="1.00000" // Saturation value to use for steering friction.  Range: 0 - 1.0
FFB steer damper coefficient="0.10000" // Coefficient to use for steering damper.  Range: -1.0 to 1.0
FFB steer damper saturation="1.00000" // Saturation value to use for steering damper.  Range: 0 - 1.0
FFB throttle vibe freq mult="0.60000" // Scales actual engine frequency to force FFB vibration frequency.  Suggested range: 0.10 to 0.50
FFB throttle vibe zero magnitude="0.02000" // Magnitude of engine vibration at 0rpm (reference point).
FFB throttle vibe slope="0.00000" // Slope of line defining magnitude as a function of frequency (used with FFB throttle vibe zero magnitude).
FFB throttle vibe wave type="0" // Type of wave to use for vibe: 0=Sine, 1=Square, 2=Triangle, 3=Sawtooth up, 4=Sawtooth down.
FFB throttle vibe update thresh="0.08000" // Amount of change required to update throttle vibe (0.0 - 1.0)
FFB brake vibe freq mult="0.10000" // Scales actual brake rotational frequency to force feedback vibration frequency.
FFB brake vibe zero magnitude="0.10000" // Magnitude of brake vibration at 0mph (reference point).

FFB brake vibe update thresh="0.05000" // Amount of change required to update brake vibe (0.0 to 1.0)
FFB rumble strip magnitude="0.27000" // How strong the rumble strip rumble is.  Range 0.0 to 1.0, 0.0 disables effect.
FFB rumble strip freq mult="0.60000" // Rumble stip frequency multiplier 1.0 = one rumble per wheel rev.
FFB rumble strip wave type="0" // Type of wave to use for vibe: 0=Sine, 1=Square, 2=Triangle, 3=Sawtooth up, 4=Sawtooth down.
FFB rumble strip pull factor="0.30000" // How strongly wheel pulls right/left when running over a rumble strip. Suggested range: -1.5 to 1.5.
FFB rumble strip update thresh="0.07500" // Amount of change required to update rumble strip effect (0.0 - 1.0)
FFB jolt magnitude="1.00000" // How strong jolts from other cars (or walls) are.  Suggested Range: -2.0 to 2.0.

Anyway you can test with preset parameters and the vibration and grip info its non-existent in sim-plicity (as said it works in Logi.., Fanat.., mmos.., ...)

I have tried many options in the Torque, Details Boost, Max. Speed, .... nothing. No one "activates" that info reading.

Thanks.

@sim-plicity-dev Hello. Have you been able to feel the cobbled road (or grip) on Sim-plicity Wheel system? Have you tried with another wheel (even with the most simple one) and after with the Simplicity?

@byagm

We've identified the cause and are looking at integration options. We should decide early next week whether to deploy the fix into v21.02.07 or v21.07.01

byAGM

@sim-plicity-dev and when will be able those updates? (Aprox)

@byagm

The fixes are incorporated in v21.07.01 which is being released to "Alpha" on Monday 8th November
