# WebGPU Unavailable? Troubleshoot by Platform & Environment

## What You're Seeing

Any3D or your browser’s environment detection reports **WebGPU unavailable**. This means `navigator.gpu` is either undefined, or the GPU adapter could not be acquired.

**Important**: Any3D currently **uses WebGL2 as the primary 3D preview engine**; missing WebGPU alone **does not** block the main preview and conversion workflow. This article is for complete environment investigation and future-proofing. If preview fails, first check the [WebGL2 Fix Guide](/blog/fix-webgl2-unavailable).

## What Is WebGPU?

WebGPU is the next-generation browser graphics/compute API. Chrome, Edge, Safari, and others are gradually enabling it by default. Any3D detects and reports WebGPU capability for diagnostic purposes; some experimental features may depend on it in the future.

## Common Causes

| Cause                                 | Typical Scenario                                              |
| ------------------------------------- | ------------------------------------------------------------- |
| WebGPU not enabled in browser         | Chrome < 113 requires manual flag; older Safari               |
| OS not supported                      | Old Windows 10 builds, unpatched macOS/iOS                    |
| Outdated GPU drivers                  | Especially Intel integrated graphics, low Linux Mesa versions |
| Enterprise/experiment switch disabled | Policy disables WebGPU or "Graphics experimental features"    |
| Virtual machine / RDP                 | No GPU virtualization                                         |
| Extensions or privacy tools           | May block `navigator.gpu` (rare)                              |

## Troubleshoot by Platform

### Windows

1. **Chrome 113+ / Edge 113+**: Open `chrome://gpu` in the address bar and verify WebGPU status is **Hardware accelerated** or **Available**.
2. Older versions need `chrome://flags/#enable-unsafe-webgpu` (newer versions have it enabled by default, no manual flag needed).
3. **Update Windows 10/11** and GPU drivers; WebGPU relies on a relatively new DXGI/D3D12 stack.
4. **Group Policy**: Enterprises may disable "Experimental Web Platform features".
5. **RDP / Hyper-V VMs**: Often lack WebGPU; test on a local physical machine.

### macOS

1. **Safari 17+** (macOS Sonoma+) or **latest Chrome**.
2. Apple Silicon has good support; Intel Macs require a recent macOS version and drivers.
3. MDM restrictions on "Beta features" may affect WebGPU experimental switches.

### Linux

1. Latest Chrome + **Mesa 22+** or NVIDIA driver 525+.
2. Vulkan support is a common prerequisite: run `vulkaninfo` to check quickly (advanced users).

### iOS / iPadOS

1. **Safari 17+** (iOS 17+) gradually adds WebGPU support.
2. System must be updated; managed devices may be delayed by administrators.
3. Chrome on iOS uses WebKit, so it shares Safari's capabilities.

### Android

1. **Chrome 121+** enables WebGPU by default on some devices; low‑end devices may still lack it.
2. Update Chrome and system WebView; if the GPU is too old, the browser silently degrades.

## Network, VPN & Enterprise Intranet

WebGPU is a local API, **not directly blocked by VPNs**. Indirect scenarios:

| Scenario                      | Explanation                                                           |
| ----------------------------- | --------------------------------------------------------------------- |
| Enterprise browser image      | Custom Chromium may compile with WebGPU disabled                      |
| Intranet only allows old Edge | No WebGPU; IT needs to push a newer version                           |
| Zero‑trust client             | Rarely modifies `navigator.gpu`; if suspected, test in incognito mode |

## Parental Controls & Supervision

- **Blocking system/browser updates** → WebGPU permanently unavailable; allow automatic updates to fix.
- **Child profiles** generally do not disable WebGPU; if using a minimal browser, switch to Chrome/Safari.

## Step‑by‑Step Fix (General)

1. Update **OS + browser + GPU drivers**.
2. Check `chrome://gpu` for WebGPU entry; follow prompts to update or enable.
3. Run on a physical machine, not RDP/VDI.
4. Use incognito mode to rule out extensions.

## Quick Self‑Test

```js
typeof navigator.gpu !== "undefined";
```

Async adapter detection (Console):

```js
navigator.gpu?.requestAdapter().then((a) => console.log(a ? "adapter ok" : "no adapter"));
```

`no adapter` is common with old drivers, VMs, or no compatible GPU.

## Relation to Any3D Features

| Feature                              | When WebGPU Is Missing |
| ------------------------------------ | ---------------------- |
| 3D preview (WebGL2)                  | Usually unaffected     |
| Format conversion / WASM compression | Unaffected             |
| Future WebGPU‑accelerated features   | May be unavailable     |

## Summary

WebGPU unavailability is mostly due to **outdated system/browser/drivers, virtual machines, or enterprise‑locked old browsers**. Any3D core functionality relies on WebGL2 and WASM; if only WebGPU is flagged and the tool works fine, you can ignore it for now, but keep system and browser updated for better performance in the future.
