# Browser Graphics Optimization for Windows
> Experiencing slow 3D graphics in Voyager? Ensure your Windows PC is fully utilizing its available hardware.
> **Note:** This article applies to **Windows operating systems only**.
Overview
When first working in Voyager, some users may notice reduced graphics performance—most commonly lag or stuttering when rotating complex 3D reconstructions.
In many cases, this behavior occurs because the web browser is not configured to use the system’s dedicated (standalone) GPU. Adjusting Windows graphics settings to prioritize high-performance hardware can significantly improve rendering performance.
Follow the steps below to ensure your browser is using the highest-performance GPU available:
1. Open **Graphics Settings** by typing *“graphics settings”* into the Windows search bar and selecting the result.
2. Under **Graphics performance preference**, select **Desktop app** from the dropdown menu, then click **Browse**.
3. Locate your browser’s executable:
* For **Google Chrome**, navigate to:\
`C:\Program Files\Google\Chrome\Application`
* Other browsers will follow a similar installation path.
4. Select the browser application file and click **Add**.
5. Once the browser appears in the application list, select it and click **Options**.
6. Choose **High performance** (the highest-performance GPU available), then click **Save**.
7. Restart your PC to apply the changes.
8. Reopen Voyager and verify that graphics performance has improved.
