Browser Compatibility and Performance
LMI recommends Chrome, Firefox, or Edge for use with the Gocator web interface.
If you choose to use other browsers, please note the following limitations.
Internet Explorer 11 Switches to Software Rendering
If you use sensors with large datasets on Internet Explorer 11, you may encounter the following issue.
If the PC connected to a sensor is busy, Internet Explorer may switch to software rendering after a specific amount of time. If this occurs, data is not displayed in the data viewer, and the only reliable way to recover from the situation is to restart the browser.
It is possible to remove the time limit that causes this issue, but you must modify the computer’s registry. To do so, follow Microsoft's instructions at https://support.microsoft.com/en-us/help/3099259/update-to-add-a-setting-to-disable-500-msec-time-limit-for-webgl-frame.

Other Internet Explorer 11 Limitations

Forcing the GUI Browser or Emulator to Use Dedicated Graphics Card
Many laptops contain two different graphics cards: a lower-performance graphics card integrated into the CPU and a higher-performance dedicated graphics card. When working with scan data containing a large amount of data, you may see low frame rates in the data viewer if the laptop uses the integrated graphics card. To get the best performance, you can choose the dedicated graphics card as the default for the browser you use or for the emulator. For the emulator, you choose the default for CefSharp.BrowserSubprocess.exe in the \bin\cef\win64 folder in the tools folder:
For the browser, choose the executable for your browser.
The following links provide steps to choose a default (use CefSharp.BrowserSubprocess.exe or your browser's executable instead):
