Find the cause of a blank screen or slow run

Describe the symptom precisely

Start with one question: did the page fail to open, did its text appear without the 3D scene, or did the scene load and run slowly? Those observations point to different checks. The original entry requires JavaScript and WebGL; a loaded page title alone does not demonstrate a working game renderer.

• Page access error: record the exact address, time and browser message.
• Missing scene: inspect script permissions and browser graphics support.
• Slow scene: compare graphics quality under similar conditions.

Use a small, repeatable comparison

The secondary graphics reference records quality choices, Show FPS and Battery saver. Change one setting, repeat a similar short section, then decide whether the result helped. Lower power use and higher frame rate are different goals; choose the one you need.

On a phone, begin with a short session and check whether the controls remain comfortable as the screen becomes busy. Our review did not include physical-device benchmarks, so there is no promise that a particular phone or browser will maintain a specific frame rate.

Make the next report actionable

Record version, device, browser, symptom and the one setting you changed. Keep an error screenshot when possible. A concise sequence such as “opened the original URL, menu loaded, scene stayed blank” gives a clearer starting point than “it does not work.”
