If you are receiving an error message stating that your web browser is “Incompatible” when launching VISTS, this indicates that your computer is unable to display our content in your browser.
This can happen for one of several reasons:
Your Web Browser may be incompatible with WebGL
The VISTS software presents motion graphics content in the WebGL format. Google Chrome supports WebGL, so you will want to ensure you are using Google Chrome to launch the VISTS simulation.
Your Web Browser may be out of date
An outdated browser may not work properly with the most recent version of WebGL, so updating your web browser can often solve an "Incompatible Browser" error message.
To see your version of Chrome, and to ensure your browser is up to date, copy and paste the following link into your Chrome browser's navigation bar and press "Enter":
This will automatically update the browser if it is out of date.
: If you do not see "(64-bit)" listed at the end of your browser version, then you are running the 32-bit version. We recommend a 64-bit processor
for running VISTS.
Your computer's Graphics Driver may need to be updated
If your graphics driver is out of date, or malfunctioning, this can affect your browser's ability to display WebGL content. This is more likely when multiple browsers are presenting the above error message.
Updating your Operating System
On a windows computer, you can perform a Windows Update, which will usually include the latest drivers for your graphics card. You can also check your Device Manager and click on "Display adapters," then right-click on your graphics processor / graphics card to "Update Driver."
Hardware Acceleration may be turned off in your browser
It's possible that, in troubleshooting an issue unrelated to our simulation, you or someone else may have turned off Hardware Acceleration
in your browser settings. This can produce the above error, as Hardware Acceleration is needed, although this setting is normally turned on by default.
Your computer's hardware may no longer be supported by the manufacturer with driver updates
If your computer's graphics processor is no longer supported with updates by the manufacturer, then your computer's hardware may no longer be compatible with WebGL's latest version. In this case, you'd need to use a different computer.
