OpenBrIM Launcher

Chrome throttles background tabs to save resources, which can significantly slow down analysis and result extraction when minimized.

The OpenBrIM Launcher configures Chrome for optimal performance:

Feature	Benefit
Background analysis	Runs at full speed when minimized
Result extraction	~50% speed when minimized (vs. near-zero without)
Isolated profile	Keeps OpenBrIM sessions separate from regular browsing

Download: OpenBrIM-Launcher.bat

No installation or admin privileges required. On first run, enter your company name (e.g., companyname for companyname.openbrim.org). The launcher saves your preference for future use.

Enhancing Platform Performance

Laptops and browsers often conserve battery by limiting hardware utilization. Adjust these settings for optimal performance.

Use Discrete GPU

Step 1: Check which GPU Chrome is using. Open chrome://gpu/ and find "GL Renderer".

Default: Chrome using integrated Intel graphics

Step 2: Open NVIDIA Control Panel (search "Nvidia" in Windows). Select Chrome or Edge and assign "High Performance Nvidia Processor".

NVIDIA Control Panel GPU assignment

Step 3 (Alternative): Search "Graphics Settings" in Windows, select "Desktop App", browse to your browser's .exe file, click "Options", and set your preferred GPU.

Windows Graphics Settings

Step 4: Verify by reopening chrome://gpu/. Intel should no longer appear under "GL Renderer".

Success: Chrome now using discrete NVIDIA GPU
