Tracking in Racing Sims (ACC / PC2)

Wine Bridge Issue Description

I have two games with a Steam Proton prefix which needs to get connected via winebridge. Building and AppImage works both to install the bridge as documented but even though the camera is active, there is no tracking ingame. On the other hand tracking via winetricks in the same prefix works.

Lets pretend I am just using the build.

Steps to Reproduce

  1. Build linuxtrackx
  2. Start ltr_gui
  3. Install winebridge for Steam Games "Assetto Corsa Competitione" (ACC) and Project Cars 2"
  4. Close ltr_gui
  5. Start one of the games via Steam in "Steam VR Mode"

Expected Behavior

Tracking should happen in the cockpit-helmet view (like under Windows)

Actual Behavior

  • Both: Light of the camera goes active when loading the track (not when entering the game, which would be expected)
  • ACC: No tracking; But:
    • Alt+Tab back
    • open ltr_gui
    • start tracking via the button
    • Tracking works in the cockpit (non-helmet) and external views. It feels more like a cooliehat than a headtracking (it is smooth but the supported views are normally for cooliehats or mouse and not for heads)
  • Project Cars 2: No tracking at all

Checklist

  • I have Wine installed and working
  • I have tested with a supported game
  • I have included Wine version information
  • I have tried different Wine configurations
  • I have checked Wine prefix permissions

Fixing approaches

I tried to start tracking in the Steam prefixes (e.g. WINEPREFIX=/media/user/Games/Steam/steamapps/compatdata/805550/pfx winetricks) with executing the Controller.exe and Tester/64.exe manually. They all work as expected.

I use SteamTinkerLaunch to execute the Controller.exe as a forked process before gamestart as describerd here.

I used different Steam Proton Versions (9 - 10.5).

It is not clear to me, what has to happen in the prefix before gamestart (is the Controller.exe necessary?).

I checked ls /usr/local/lib/linuxtrack/wine_bridge/ which was not found (is this up to date?).

I checked:

$ WINEPREFIX=${my_steam_pfx} wine reg query "HKLM\\Software\\Classes\\CLSID\\{98BF1CE3-0x0000-0000-0000-000000000000}"

0090:err:ntoskrnl:ZwLoadDriver failed to create driver L"\\Registry\\Machine\\System\\CurrentControlSet\\Services\\winebth": c0000135
reg: Key not found

Same goes for wine NPClient64.dll # Should not crash (crashes with "not found" but wine "C:\Program Files (x86)\Linuxtrack\NPClient64.dll" works.

Unfortunately, I have no official supported game on this machine to test. If this will give the important knowledge of the problem I will try to get one for testing...
