Graphics acceleration is off 3D simulations can’t run here yet Graphics acceleration is on

3D simulations run slower without it. Turning it on is recommended.

The simulations need WebGL 2, which isn’t available in this browser right now. Turning on hardware acceleration usually brings it back; if not, update the browser or the graphics driver.

3D simulations are running with hardware acceleration. Nothing to change.

On a college lab computer this setting may be locked. If so, ask the lab in-charge.
