Specs

Settings / Advanced Settings

• GPU Acceleration: [ Enable / Disable ]
  • (Info button or tooltip:Enhance model performance by utilizing your device's GPU for acceleration.)
• GPU Options: [ Nvidia / AMD ] (visible only when GPU Monitoring is enabled)
  • Default: Auto-select GPU with highest VRAM

GPU Monitoring Toggle:

• When toggled on, reveal the GPU selection dropdown for Nvidia and AMD.
• Default to the auto-selected GPU with the highest VRAM.

GPU Monitoring Warning:

• If the user toggles on GPU monitoring, provide a brief explanation of how it can improve model performance.
• Optionally, warn that enabling GPU monitoring may have a slight impact on system resources.

GPU Selection:

• Use a dropdown to allow users to manually select Nvidia or AMD when GPU monitoring is enabled.
• Default to the auto-selected GPU with the highest VRAM.

Device Compatibility Check:

• Before applying changes, check if the user's device has a compatible GPU.
• If not, display an error message and prevent the user from enabling GPU monitoring until a compatible GPU is detected.
  (Optional: provide a suggestion or link to update GPU drivers or install a compatible GPU).

Feedback:

• Display a success message upon applying changes.

GPU monitoring has been successfully enabled.

• Or when user disables GPU monitoring without any specific issues.

GPU monitoring has been successfully disabled.

• In this case, changes don't require a restart.

Error scenarios:

1. User tries to enable GPU monitoring, but their device doesn't have a compatible GPU

GPU Monitoring cannot be enabled on your device.
Your current device does not have a compatible GPU for monitoring. To enable GPU monitoring, please ensure your device has a supported Nvidia or AMD GPU with updated drivers.

2. GPU Selection with Incompatible GPU

User wants to select a specific GPU for monitoring, but that GPU is not compatible -> incompatible GPU will be disable.

3. GPU Monitoring Turned Off with Compatible GPU

User attempts to turn off GPU monitoring when they have a compatible GPU.
Tooltip when hover warning icon:

Disabling GPU Acceleration may result in reduced performance. It's recommended to keep this enabled for optimal user experience.

Out-of-scope:

• Not support AMD for now.
