Slow Scanning Speed (FPS) or Software Lag Issues⭐

Symptom

The scan FPS operates lower than the maximum FPS.

The scanning process is not interrupted, nor is the scan target recognition affected, but there is noticeable lag within the software itself.

Lag is experienced even when moving the mouse or performing other actions during scanning.

The scanning speed(FPS) has slowed.

Maximum FPS by Scanner Model

• i500: 30 FPS
• i600: 35 FPS
• i700, i700 wireless, i900, i900 classic, i900 mobility: 70 FPS

Troubleshooting

1. Check Live View and Scan Noise

Review the scan again or check the actual scanning process to verify if noise is present.

Check if excessive filtering appears in the live view or if camera noise occurs.

If excessive filtering or noise is detected, clean the new tip and polarizing filter to ensure a clean live view.

2. Check CPU Performance During Scanning:

Run Windows Task Manager (Ctrl + Shift + Esc) → Performance → Check CPU Speed and CPU Utilization.

Ensure you check these metrics while scanning. CPU speed and utilization will naturally be lower when not scanning.

Normal CPU Performance During Scanning	Limited CPU Performance During Scanning
CPU Utilization: Over 80% CPU Speed: Over 3.0 GHz	CPU Utilization: Below 30% CPU Speed: Below 2.0 GHz If these values are low, the system might be intentionally throttling CPU performance (for power-saving purposes, etc.).

3. Optimize CPU Performance Settings

1) Check Laptop Charger Connection

If the laptop is not connected to a charger, the system may intentionally reduce performance to save battery.

2) Adjust Windows Power Settings:

• Go to:
  Control Panel → Power Options → Change Plan Settings

• Change advanced power settings → Processor power management → Minimum/Maximum processor state 100%

• Go to Control Panel > All Control Panel Items > Power Options > Change advanced power settings > USB settings. Disable both the on-battery and plugged-in USB selective suspend settings.

• Go to Control Panel > All Control Panel Items > Power Options > System Settings. For both On battery and Plugged in, select "Do nothing" for "when the lid is closed."

4. Use Manufacturer's Performance Utility

Launch the manufacturer’s performance utility to set the laptop to high-performance mode. The name and availability of these utilities may vary by manufacturer. These settings may be available in sections such as Performance, Power Management, or Thermal Management.

Some manufacturers may pre-install utilities or offer downloadable versions.

5. Update Graphics Card Drivers:

Download the latest graphics card drivers from the official NVIDIA website.

6. NVIDIA Control Panel Settings

Ensure your graphics card is running at maximum performance through the NVIDIA Control Panel.

Steps:

1) 3D Settings → Manage 3D settings → Global settings

2) Preferred graphics processor → High-performance NVIDIA processor

3) Power Management mode → Prefer maximum performance

7. Check Scanning Experiences Setting

Check to see if the scanning experience is set to "Fast & Furious."

• If the scanning experience is not configured to "Fast & Furious," the "Medit Scan for Clinics" program does not maximize scan speed for its intended purpose.

Smooth & Steady

• Designed for use on PCs with built-in CPUs that can't handle the i700 and i700 wireless scanners' maximum speed. Alternatively, even if your PC specifications support the maximum speed of the i700 and i700 wireless scanners, choose this option if you want to adjust the number of scanned images acquired per second.
• The program increases the speed of the rendering process by adjusting the Scanning FPS (number of scan images acquired per second) so that you can enjoy a smooth scanning experience.

Automatic

• This option adjusts the Scanning FPS based on the PC's specifications.
• When the Scanning FPS falls below the reference value (currently 40FPS), the program behaves like Smooth & Steady, allowing to adjust the Scanning FPS (number of scan images acquired per second) to increase the rendering process speed.

Fast & Furious

• Obtain scan data at the maximum speed of i700 and i700 wireless scanners.
• The i700 and i700 wireless scanners can achieve a maximum speed of 70 frames per second, depending on the PC used.
• This option gives you the same scanning performance as when you use the i700 with Medit Link prior to v2.6.0.
• A PC with an Intel Core 12th generation CPU, which is the recommended PC specification for the Medit intraoral scanner, will provide the best scanning performance.

8. Check the specifications of your PC

1) Verify PC Specifications

Check the specifications of your PC to check if it satisfies the system requirements for your scanner. The scan speed may have slowed if either the PC specification or the employing PC does not give enough power to operate the scanner on the Medit Scan for Clinics software.

• System requirements

2) Check for Windows and Driver Updates

• Update the Windows, motherboard's chipset driver and GPU.

3) Reinstall the Medit Link application.
