rFactor telemetry HUD overlay
rFactor 2, rFactor and Game Stock Car Extreme expose their telemetry through a free community shared-memory plugin. Install it once; Horizon Labs does the rest.
Setup
Pick your game in Horizon Labs (Settings → Connection), then switch on its telemetry:
- rFactor 2
- Install
rFactor2SharedMemoryMapPlugin64.dll(rF2SharedMemoryMapPlugin) inBin64\Plugins, then enable it in Settings → Gameplay → Plugins. - rFactor
- Install
rFactorSharedMemoryMap.dll(rFactorSharedMemoryMap) in the game’sPluginsfolder. - Game Stock Car Extreme
- Install
rFactorSharedMemoryMap.dll(rFactorSharedMemoryMap) in the game’sPluginsfolder.
- Horizon Labs does not ship these plugins: download them from their authors.
- Run the game in borderless windowed mode so the overlay can sit on top.
What the HUD can show
The fields each game sends, as Horizon Labs reads them. The Designer lets you bind any of them to any layer.
