LOCAL DIAGNOSTIC
Check the browser.
Know your next step.
A quick capability check for this browser and device. No game files or GPU identifiers are collected.
Ready when you are.
This checks a prerequisite, not a game's frame rate or full compatibility.
Local processing · No account · No game download
What the result means
The check looks for a secure browsing context and the WebGPU API, then asks the browser for an adapter. It does not request a GPU device, run a benchmark or read vendor identifiers. An unavailable adapter can reflect browser, device or policy restrictions.
If all checks pass, return to the game's own launcher. Passing here does not establish that a specific game build, asset download or rendering path will work. D2 Survivors file setup is a separate prerequisite; this test does not validate an installation.
What to do next
If the API is missing, use a current browser on a supported system. If the adapter is unavailable, update normally and check the browser's graphics information or ask your device administrator. Avoid changing security settings simply to get a green badge.
