Wheel runs to full lock in pause menu: FFB pass-through not released when telemetry pauses (G923 / Forza Horizon 6)

[aakanojia]

Environment

• Wheel: Logitech G923 (PlayStation 4/PC variant), native mode, PID 0x046D:0xC266
• Game: Forza Horizon 6
• Plugin: TrueForce For All v0.1.18
• SimHub: 9.11.13 (Free), running as Administrator (needed for USBPcap)
• USBPcap: 1.5.4.0
• OS: Windows 11

Summary

While driving, everything works great. The moment I open the pause menu, the wheel turns hard to full lock (left or right) and holds there until I unpause. In the pause menu the plugin shows "Waiting for telemetry" ('FH6' is detected but no telemetry is arriving. You may be in a menu or paused), so the UDP telemetry has clearly stopped, but the wheel is still being driven to lock.

Steps to reproduce

1. G923 in native mode, plugin bound, FFB pass-through active (log shows UsbPcapFfbTap started).
2. Drive in free roam or a race. FFB feels correct.
3. Open the pause menu.
4. Wheel snaps to full lock on one side and stays there.
5. Unpause. Back to normal immediately.

Relevant log lines

[Trueforce] Found Logitech G923 (PS/PC)  (VID 0x046D, PID 0xC266).
[Trueforce] UsbPcapFfbTap started: \\.\USBPcap2 dev 39
[Trueforce] Forza UDP source listening on 0.0.0.0:5300.
(on pause) UI: "'FH6' is detected but no telemetry is arriving. You may be in a menu or paused."

Root cause (from reading the code)

• The FFB pass-through (UsbPcapFfbTap) mirrors raw HID++ FFB to the wheel and is not gated by the telemetry/pause state. TryGetFreshFfbTarget(maxAgeMs) only checks sample age, and as the code notes the tap cannot distinguish a game that is still sending a steady force from a game that stopped sending. In the FH6 pause menu Forza keeps sending an FFB packet (behaves like an auto-center), so the tap keeps treating it as fresh and the wheel is driven to lock.
• There is no watchdog that zeros or centers FFB when telemetry pauses. The telemetry source already knows data stopped (that is what flips the UI to "Waiting for telemetry"), but that state does not reach the pass-through path (FfbTargetProvider keeps reading _ffbTap.TryGetFreshFfbTarget regardless).

Suggested fix

• When the active telemetry source reports paused / no-data (the same condition behind the "Waiting for telemetry" banner), force cur to 0x8000 (silence center) in the pass-through, or fade it out, until telemetry resumes. In short, gate FfbTargetProvider on the paused state. That releases the wheel in menus without touching in-game FFB.
• Nice to have: expose SkipFfbPassthrough (or a dedicated "release FFB on pause" toggle) in the UI for non-native-TrueForce games too, so users can opt in without hand-editing TrueforcePlugin.GeneralSettings.json.

Notes

Happy to test a build. Repro setup is G923 PS/PC + Forza Horizon 6 + SimHub running as admin. Great plugin otherwise, the telemetry effects feel excellent.

Thank you for the report and kind words; I'm glad you're enjoying it! Really appreciate the root cause and suggested fix.

Literally couldn't be more helpful!

I actually ran into this same issue a couple hours ago while testing the upcoming build in FH6. I essentially applied the same fix to what you suggested. Hoping to get this build out tonight! Once that releases, let me know if you're still running into this.

Fix was working in most pause situations. When matchmaking in FH6 once a match was found it would pull to full lock and vibrate aggressively. Narrowed it down to the centering spring.

Disabling centering spring when playing FH6 solved the issue. investigating a real fix.

Hi im still having the Problem with the Full Lock to the Left or Right did you disable Center spring scale in the FH6 settings? because i cant find any other settings that controls the Center spring

The in-plugin stationary spring is what was causing problems.

You shouldn't have to touch the in-game settings.

Within the plugin you should see a toggle to enable "stationary spring" make sure it's off. If you're playing Forza it shouldn't do anything whether on or off anymore, but worth checking anyway.

When you experience the issue, what were you doing in game? Pausing? Switching races? Etc?

I haven't had the issue anymore in my testing so I'm curious what could be going on for you.

If you're able to reliably reproduce it; would you be willing to go into the plugins diagnostics and enable byte logging, open the game, cause the the full lock issue, and then export your logs and attach them here?

That would be super helpful.

Thank you!

Oh ok i already had the „Stationary Spring“ setting unchecked since it already said that it doesn’t do anything in Forza.

The problem happens almost everytime the game „pauses“ it doesn’t matter if I manually pause the game or start a race or Quick travel.

I don’t know if it’s helpful or not but I downloaded the Plugin from GitHub instead of Nexus mods since the Version on Nexus was lower then the GitHub version

I was about to ask if you were on the latest version. Seems like you probably are.

Very strange because on my GPRO I don't have that issue anymore. Which wheel are you on?

Whenever you have a moment those logs would be extremely useful

I am using the Logitech G923 PS version

So i found out how to recreate the problem everytime. When you are stationary in the game, the Wheel gets really hard to turn (i think its trying to simulate the tires scrubbing on the ground) and when you fast travel, start race or teleport home the wheel does the "Full lock" and slams either to the left or right. BUT when you try the same (fast travel etc.) after moving the car a bit, so that the steering wheel gets softer and easier to turn, the "Full Lock" problem doesnt happen.

I dont really know for what i should look in the Log files so i just put the entire Zip in there. i hope its usefull

Thank you for testing this. When I get a chance to use my rig I'll see if I can reproduce it on my G PRO too.

I did find something in the code that might be causing it on our end, and I have a fix I want to try. The tricky part is that Logitech has flagged this same thing, the wheel spinning to one side and locking, as a known FH6 issue on its own, separate from our plugin. So it's probably two overlapping problems, and not all of it may be ours to fix.

When you get a chance; could you fully close SimHub (make sure it isn't still running in the system tray or in the background), then try to trigger the lock the same way in FH6? If it still happens with SimHub completely closed, that points to the game rather than the plugin. Just want to rule that out.

Ok i tried recreating the problem with:

SimHub Open but Logitech Hub Closed: The Problem still occurs

SimHub Closed and Logitech Hub Closed: The problem doesnt happen

SimHub Closed and Logitech Hub Open: The Problem doesnt happen

I also tried disabling the Plugin while in game, it also fixes the problem.

I noticed when i dont use the Plugin the Wheel auto centers itself everytime i pause the game, i think something is colliding with the Auto Centering from Forza and the Plugin

Thank you! Yeah, this testing definitely points at it being our issue.

I noticed the game auto centers when paused too. Ideally, I want to keep that behavior but in trying to solve this issue I disabled FFB during pause which of course broke that. It solved some lock issues but it's just still not reliable and isn't the ideal solution.

I'm gonna take a good look at this when I get to my rig and see if I can get to the bottom of it.

I really appreciate the report and testing! Will update this thread when I make some progress or find anything interesting.

Was able to take a look an I think I may have a fix. The fix also restores the built in FH6 auto centering on pause which is nice.

Since I don't have a g923, and wasn't able to replicate the issue on my GPRO, I can't be sure this works until someone else tests it.
When you get a sec, run this updater and it'll apply the fix. If it works, I'll publish it as a hotfix to everybody.

Hey so,

I updated the Plugin and tried recreating the problem with the Updated version again and it still happens. But this time it does it a little different, when you just pause the game it automatically re-centers the Wheel (which is ok), but when you quick travel after pausing the game, the wheel Full Locks itself again.
