Migration guide
Chrome 138 deprecates GPUAdapter.isFallbackAdapter. The replacement is GPUAdapter.info.adapterType, which returns a richer enum value instead of a boolean. Detect what your adapter actually is, and use the migration checker to flag deprecated usage in your own code.

old API vs new API
Before Chrome 138
deprecatedconst adapter = await navigator.gpu
.requestAdapter();
// Boolean — only tells you
// whether it's a software fallback
if (adapter.isFallbackAdapter) {
showFallbackWarning();
}Chrome 138+
recommendedconst adapter = await navigator.gpu
.requestAdapter();
// Enum — richer information
const type = adapter.info.adapterType;
// "discrete-gpu" | "integrated-gpu"
// | "cpu" | "unknown"
if (type === "cpu") {
showFallbackWarning();
}| adapterType value | Meaning | isFallbackAdapter equivalent |
|---|---|---|
"discrete-gpu" |
Dedicated GPU (NVIDIA, AMD, etc.) | false |
"integrated-gpu" |
GPU built into the CPU die | false |
"cpu" |
Software rasterizer (WARP, lavapipe) | true |
