# Browser requirements

> What the viewer and Space need from your browser and machine

The viewer and Space render real 3D in the browser with WebGL. A current **Chrome**, **Edge**, **Safari** or **Firefox** on a desktop or laptop is the target; phones can open the feed and the viewer, but Space is built for a mouse.

* **Hardware acceleration** must be on. It is by default; if models render slowly or not at all, check your browser's system settings.
* **Big models need memory.** A Max clone can be a 50 MB file with a million triangles. Close other heavy tabs if the viewer stalls.
* **Ad blockers** occasionally block the model download. If a viewer stays empty, try the page once with the blocker off.
* **Sign-in** uses a Google pop-up. Allow pop-ups for unrealizex.com if the button does nothing.

<Tip>The **I** key in Space shows a stats overlay with the frame rate and triangle count, which tells you quickly whether the model or the machine is the bottleneck.</Tip>
