Common Issues

GPU Not Detected

Problem: SmartBlur shows "No GPU found" or runs in CPU mode.

Solutions:

1. Update your graphics drivers to the latest version.
2. In Settings > GPU, manually select your GPU from the dropdown.
3. If you have both integrated and dedicated GPUs, make sure SmartBlur is set to use the dedicated one.
4. Some laptops require changing the GPU preference in Windows Settings > System > Display > Graphics.

Virtual Camera Not Appearing

Problem: Other apps don't show "SmartBlur Virtual Camera" as a camera option.

Solutions:

1. Restart your PC after installing SmartBlur.
2. Close and reopen both SmartBlur and the other app.
3. Make sure SmartBlur is running before opening the other app.
4. In SmartBlur, disable and re-enable the virtual camera.
5. Run SmartBlur as Administrator (right-click > Run as admin).

Poor Detection Accuracy

Problem: Faces are not being detected, or false positives are appearing.

Solutions:

1. Increase detection sensitivity in Settings.
2. Enable 360-degree mode for non-frontal faces.
3. Reduce minimum face size for distant faces in group photos.
4. Make sure images are not extremely low resolution or heavily compressed.

Slow Processing

Problem: Video or batch processing is taking too long.

Solutions:

1. Enable GPU acceleration in Settings.
2. Reduce the number of detection targets (disable body detection if not needed).
3. Lower detection sensitivity if high accuracy is not critical.
4. For batch processing, increase the thread count in Settings.

App Crashes

Problem: SmartBlur crashes during processing or on startup.

Solutions:

1. Check that your graphics drivers are up to date.
2. In Settings > GPU, try reducing the VRAM limit.
3. Disable GPU acceleration and try CPU mode.
4. Clear the app cache: close SmartBlur, delete %APPDATA%/SmartBlur/cache, and restart.
5. Check the log file at %APPDATA%/SmartBlur/logs/ for error details.

License Activation Fails

Problem: "License not found" or "Device limit reached" when activating.

Solutions:

1. Check that you entered the license key correctly (no extra spaces).
2. Make sure you have an internet connection for the first activation.
3. If you've reached the device limit, deactivate a previous device first.
4. Contact support if the issue persists.

Blurry Output or Missing Faces

Problem: The output image has unexpected blur areas or some faces are not blurred.

Solutions:

1. Increase face padding to ensure complete coverage.
2. Try a different blur effect — Gaussian covers more area than mosaic.
3. Check if detection sensitivity is set too low.
4. Manually verify by toggling the detection overlay on.
