SimHub isn't detecting my game
Last updated · SimHub 9.11.22
If SimHub runs but shows no telemetry, check in this order: the game is enabled in SimHub's settings, administrator rights match between the game and SimHub, any per-game requirement is done — iRacing needs irsdkEnableMem=1 and the truck simulators need SimHub's telemetry plugin installed — nothing else has claimed the UDP stream, and the firewall is not blocking it. The admin-rights mismatch is the one people find hardest to guess: a non-elevated SimHub cannot read an elevated game's shared memory, and it fails completely silently.
Which of these applies depends on how your game sends telemetry, so it is worth knowing which mechanism yours uses before you start — the four mechanisms are explained here.
1. The game is not enabled
SimHub only watches for games you have ticked. This is deliberate — watching all of them costs startup time and resources — and it is the first thing to check because it is both the most common cause and the fastest to rule out.
Open SimHub's settings, find the game list, and confirm yours is on. If you added a game after first run, or reset your settings at some point, this is very likely it.
Enable what you play, not everything. Ticking all 95 entries makes SimHub slower to start and gains you nothing. Tick the games you actually drive.
2. Administrator rights do not match
This is the cause worth understanding properly, because nothing about the symptom points at it.
Windows will not let a normal process read the memory of an elevated one. Shared-memory games — Assetto Corsa, ACC, iRacing, rFactor 2 — publish telemetry into a memory region that SimHub reads directly. If the game or its launcher runs as administrator and SimHub does not, SimHub simply sees nothing. No error, no warning, no clue.
| Game running as | SimHub must run as |
|---|---|
| Normal user | Normal user |
| Administrator | Administrator |
| Launcher elevated, game not | Administrator — the launcher's elevation is inherited |
Match them, do not just elevate everything. If nothing needs administrator rights, run neither elevated. Elevating SimHub unnecessarily is a habit that causes its own problems later — files it creates end up with permissions that non-elevated runs cannot touch.
Steam, Epic and some anti-cheat wrappers can elevate a game without you asking. If you are unsure, Task Manager's Details tab has an "Elevated" column you can add.
3. The game needs something enabling
Several titles do not broadcast telemetry until you tell them to.
- iRacing
- Needs
irsdkEnableMem=1in its configuration. Without it the telemetry interface is not published at all and no external tool can see anything. - Euro Truck Simulator 2 and American Truck Simulator
- Need SimHub's telemetry plugin installed into the game folder, and it is x64 only. SimHub can install it for you; if you have moved or verified the game files since, it may need doing again.
- The UDP games
- Forza, the F1 and Codemasters titles, Project CARS, Gran Turismo — all have a telemetry output setting inside the game that is off by default. You have to switch it on and point it at your PC.
- Automobilista 2 and Project CARS 2
- Need Steam launch parameters for borderless mode if you are using overlays.
- Elite Dangerous
- Reads process memory using a pointer map, which breaks with every game update until the community-maintained XML is refreshed. If it stopped after a patch, that is why.
Per-title detail is on the games pages.
4. Something else has the UDP stream
For UDP games only, and the symptom is distinctive: it worked, then you opened another application, and now it does not.
A UDP stream can only be received by one application. CrewChief, Track Titan, another dashboard tool — whichever claims the port first gets the data, and everything else gets silence.
The fix is SimHub's UDP forwarding: it receives the stream and re-broadcasts it to other ports and addresses, so both applications work. The dedicated page covers the setup.
5. The firewall
Relevant to UDP games and to console telemetry, where the data does arrive over the network.
- Allow SimHub through Windows Defender Firewall on both Private and Public profiles.
- Check the network profile itself is Private. A connection marked Public isolates your PC from other devices, which breaks console telemetry entirely.
- For console setups, confirm the console and the PC are on the same network — not one on guest WiFi, and not one behind a repeater that isolates clients.
Checking whether it is SimHub at all
Two quick tests that separate SimHub from the game:
- Try a different game. If another title works, SimHub is fine and the problem is specific to the first one — go back to per-game requirements.
- Check SimHub's own current-game readout. If SimHub has correctly identified which game is running but shows no values, the connection is being made and the data is not arriving — that points at a per-game setting rather than at detection.
If no game works at all, and SimHub is otherwise healthy, disable third-party plugins and retest. A misbehaving plugin can interfere with data acquisition, and the official troubleshooting page names plugins as the leading cause of instability generally.
Common questions
Why does SimHub show no telemetry even though the game is running?
Most often the game is not ticked in SimHub's settings, or administrator rights do not match. A non-elevated SimHub cannot read an elevated game's shared memory, and it fails silently with no error at all.
Do I need to run SimHub as administrator?
Only if the game or its launcher runs as administrator — then SimHub must too. If nothing is elevated, run neither elevated. Elevating unnecessarily creates permission problems with files SimHub writes.
What is irsdkEnableMem=1?
An iRacing configuration setting that publishes its telemetry interface. Without it, iRacing does not expose telemetry to any external application, so no amount of SimHub configuration will help.
SimHub worked until I opened CrewChief.
For UDP-based games only one application can receive the stream, and whichever claimed the port first keeps it. Use SimHub's UDP forwarding, which takes the stream and re-broadcasts it so both applications get data.
Why did Elite Dangerous stop working after a game update?
It uses process memory reading with a pointer map rather than a telemetry API, and the pointers change whenever the game is patched. It stays broken until the community-maintained pointer XML is updated.
Do Euro Truck Simulator 2 and American Truck Simulator need anything special?
Yes — SimHub installs a telemetry plugin into the game folder, and it is x64 only. If you have verified or reinstalled the game files since, the plugin may need installing again.
