On certain systems with multiple video adapters, you'll need to manually configure your browser to use the correct GPU to display your scans. While both (or all) of your display adapters will likely work, using a GPU with dedicated memory and advanced processing features will allow you to handle bigger and more complex scans without your browser slowing down (or in rare cases losing sync with the scanner).
To confirm you're using the correct GPU, you'll need to navigate to the Graphics screen in Windows 11 Settings, under System > Display > Graphics. (Windows 10 instructions are at the end of the article.)
You will then need to add your browser of choice by using "Add an app"; navigate to the location of the browser executable to add it to the list. Here's an image showing the Microsoft Edge executable:
If you're struggling to find your browser executables the default paths for Edge and Chrome are:
Edge - C:\Program Files (x86)\Microsoft\Edge\Application\
Chrome - C:\Program Files\Google\Chrome\Application\
You can also find the executable location by right-clicking the shortcut and looking at the "Target" field
Once you have added the browser(s) you intend to use with THREE, you will need to assign the correct GPU to display your point clouds and meshed scans. In this case, the High Performance option is the NVIDIA GeForce GTX 1060.
For those using Apple computers, the process is a bit simpler. You can find the setting in the Apple System Preferences, under the Battery tab. Deselect the "Automatic graphics switching" checkbox to ensure you are using the high-performance GPU.
Still using Windows 10? The process is largely the same as Windows 11, but the layout and flow are a bit different. You still need to navigate to the Display settings. Scroll down and choose "Advanced Display Settings".
Then choose "Graphics Settings"
Finally, add Chrome/Edge/etc. to the desktop app list and make sure it is set to "High Performance" in the Options menu.
