"Could not start WebGPU"
The game draws with WebGPU, your browser's way of using the graphics card. Most of the time it is switched off by one setting. On a phone or tablet, see iPhone, iPad and Android.
Google Chrome
- Copy this into Chrome's address bar and press Enter:
chrome://settings/system - Switch on Use graphics acceleration when available.
It should look like this: the switch is blue and to the right.
- Press Relaunch next to the switch (or close every Chrome window and open it again).
- Open nfscrb.xyz and press Play.
Microsoft Edge
- Copy this into Edge's address bar and press Enter:
edge://settings/system - Under System and performance, switch on Use graphics acceleration when available.
- Press Restart, then open nfscrb.xyz and press Play.
Still the same message?
- Update the browser. Chrome: menu ⋮ → Help → About Google Chrome. Edge: menu … → Help and feedback → About Microsoft Edge. Restart when it asks.
- Update the graphics driver from the maker of your graphics chip (Intel, AMD or NVIDIA), or through Windows Update. Restart the computer afterwards.
- Laptop with two graphics chips? In Windows: Settings → System → Display → Graphics, pick your browser and choose High performance. Restart the browser.
- Check what the browser says: open
chrome://gpu(in Edge,edge://gpu). Next to WebGPU it should say Hardware accelerated. If it says disabled or unavailable, this browser cannot give the game WebGPU on this computer yet.
Firefox
Firefox does not give the game WebGPU everywhere yet. Use the current Google Chrome or Microsoft Edge. Your saves stay in the browser you played in, so press Download backup in the Saves panel on the home page, then Restore from file in the new browser.
Mac
Use the current Google Chrome, or Safari 26 or newer (Apple menu → System Settings → General → Software Update). If Safari closes the game, see Safari closed the game.
Windows 7 or 8
Chrome and Edge stopped updating on Windows 7 and 8 before they had WebGPU. The game needs Windows 10 or 11.
