- Games installed through Steam are configured by Beam on its own.
- For a game running on a separate Wine setup outside Steam, launch the game at least once while Beam is running, so it is recognized and configured.
- netKar PRO has to be relaunched once it has been configured.
- Use the General > Game Connection settings in the Beam Eye Tracker to manage discovered compatibility environments and to troubleshoot.

Do not useWindows version in CrossOverNot supportedGame Connection
Keep the default Head Tracking Device Emulation method selected under General > Game Connection.
-
Launch netKar PRO in CrossOver
Versions
UseWindows build of netKar PROThrough CrossOver- CrossOver is the only compatibility environment Beam supports on macOS today.
- To reach netKar PRO, Beam configures the compatibility environment it runs in, from CrossOver. It does that on its own for the environments it discovers.
- macOS asks the first time, because CrossOver keeps its environments in another app's data. Allow it, or Beam has nothing to configure. If you dismissed the prompt, or Beam still cannot configure the environment, turn on Beam Eye Tracker under System Settings > Privacy & Security > App Management, then quit and reopen Beam.
- Check in General > Game Connection that Beam found and configured it. If netKar PRO or its environment is not listed, start netKar PRO and Beam picks it up.
- Relaunch netKar PRO once the environment is configured. If it was running while that happened, close it and start it again.

Optimize
1 Basic ControlsAdjust Speed and Amplification to get started.
your eyes/headthe in-game camera
2 Advanced ControlsFine-tune each degree of freedom individually.
In the Immersive Camera, click Show Advanced Controls at the top right to fine-tune each degree of freedom individually.
3 ProfilesSwitch between Default, Demo and Community Profiles, and create your own.
Default Profile
Balanced and cockpit-ready, with both eye tracking and head tracking on. It is read-only, so you cannot break it by accident, and you can always come back to it as your baseline.
Demo Profiles
Four presets, each isolating one input, so you can learn what head tracking and eye tracking each contribute before you combine them:
- Demo - Head Movements - Relaxed
- Demo - Head Movements - Fast
- Demo - Eye Movements - Smooth
- Demo - Eye Movements - Snappy
Community Profiles
Settings other players and creators have already dialed in for specific games, shared on the Steam Workshop.
4 Too fast, too slow, jittery or sensing motion sickness?Pick what it feels like and learn about common fixes.
Too fast
Go to Immersive Camera > Profile and select the Head Movements - Relaxed profile. This is a gentle baseline and only uses head tracking. If that is still too fast, lower Speed and raise Stability on Small Head Movements. Usually a good start for flight simmers in heavy aircraft, an Airbus for instance, or for truck sims: with Stability on Small Head Movements raised, the view stays steadier while you focus on the instruments.
Once you have that dialed in, slowly raise the sliders and bring eye tracking back in. Eye tracking makes the movement feel more natural and cuts down how much you have to move your head. More in the Profiles Guide.
Too slow
Go to Immersive Camera > Profile and select the Head Movements - Fast profile. If that is not fast enough, raise Speed and tweak Amplification from there.
Especially in space and combat flight sims, checking your six usually needs quite a high Speed and Amplification setting, or individual adjustments to pitch and yaw under Show Advanced Controls. More in the Profiles Guide.
Jittery
Lower Speed and raise Stability on Small Head Movements and Stability on Small Eye Movements.
If it still shakes, raise Head Tracking Smoothing and Eye Tracking Smoothing under Tracker in the settings. Both steady the signal against webcam noise and low light. Higher values are smoother but add latency.
Glasses, room lighting and camera position affect this as well. More in the jitteriness section on our support page.
Latency
Raise Speed, and lower Eye Tracking Smoothing and Head Tracking Smoothing under Tracker in the settings, since smoothing buys steadiness with delay.
Good light can help as well, as some webcams lower their frame rate in dark environments to increase exposure. If you choose to target a higher fps camera, check out our webcams page.
Motion sickness
If you feel nausea or dizziness after your first try, the default settings might be too sensitive for you. Go to Immersive Camera > Profile and select the Head Movements - Relaxed profile. This is a gentle baseline and only uses head tracking. If that is still too fast, lower Speed and raise Stability on Small Head Movements.
That is usually a good starting point: settle into it first, then adjust slowly, adding eye tracking and tuning from there. More in the Profiles Guide.
Troubleshoot
Antivirus (Kaspersky, etc.) flagged the Optimized driver?A false positive. The file is safe, it is Beam's own driver.
Kaspersky is the scanner we see this from most: it quarantines NPClient64.dll as a trojan. Other antivirus programs can react the same way. The file sits under Beam's interop\optimized folder and is the Optimized driver introduced in 2.6. Games load it to receive the tracking signal, and that is what heuristic detections react to. It is not harmful, and we report every detection to the antivirus vendor. The default Compatibility driver is not normally flagged.
To keep using Optimized, restore the file from quarantine and add both Beam folders to your antivirus exclusions: the BeamEyeTracker folder inside C:\Program Files\Eyeware, and the Beam Eye Tracker folder inside C:\Users\[your username]\AppData\Local. Then restart netKar PRO. If you do not need Optimized, set Driver back to Compatibility under General > Game Connection.
Tell us which antivirus it is, on Discord or at [email protected], so we can report it to the right vendor.

Beam lists the environment netKar PRO runs in under General > Game Connection. If it is still missing after starting netKar PRO once with Beam running, contact support.
Every environment starts on the Compatibility driver. Optimized gives smoother in-game camera movement and is set per environment.
Listed with a warning that the Steam Linux Runtime is unavailable? In your Steam library, install Steam Linux Runtime 3.0 (sniper) (under Tools), fully restart Steam, then click Refresh under General > Game Connection.
