Phosphn needs WebGL2

This browser could not open a WebGL2 canvas, so the engine cannot start.

Your browser does have WebGL, so this is not a browser too old or acceleration switched off: the graphics driver is being held back from WebGL2, usually by the browser's own blocklist. In Firefox, open about:support and read the Graphics section, which names the driver and the reason. Updating the graphics driver from the GPU maker, rather than Windows Update, is what normally clears it.

• Use a recent Chrome, Edge, Firefox or Safari 15+, on a desktop or a phone.
• Turn on hardware acceleration in the browser settings.
• In Safari, enable Develop → Experimental features → WebGL 2.0 if it is off.
• Remote desktops and some virtual machines have no GPU to draw with.
