We enabled WebGPU feature flag on Safari on iOS 18.2. This does give Safari an access to GPU but WKWebView still doesn't have GPU access.

Can WKWebView not access GPU through Safari feature flag? Is there some other mechanism through which we can enable GPU access for WKWebView?

We are testing gpu access by loading : https://webgpureport.org/

@saalisumer_microsoft these feature flags only impact Safari and not WebKit generally. For WKWebView, the feature will work when its enabled by default.

Can you please try on the iOS 26 beta? WebGPU is enabled by default there.
