Treat exposed features and limits as the capability surface of this browser, driver and device combination.
IP-SYS-01 / EXPOSED SYSTEM CAPABILITIES
WebGPU Feature and Limits Test
Request a WebGPU adapter and inspect browser-exposed features and limits.
A modern GPU compute or rendering application reports WebGPU unavailable.
This focused entry uses the shared Browser hardware protocol. The measurement logic and Evidence version remain identical to the complete lab.
Remove the easiest false alarms first.
01
Use a current secure-context browser and note whether hardware acceleration is enabled.
02
Compare browsers without changing drivers, power mode or display attachment.
03
Use the real target media or workload after capability queries; prediction is not execution.
Run one repeatable protocol.
- 01
Open the hardware capability report in a secure context.
- 02
Inspect adapter availability, features and limits.
- 03
Compare the same device in a current Chromium browser.
Evidence the result should expose.

Separate observed, review and inconclusive.
Compare the same machine in another current browser and check acceleration or blocklist state before changing hardware.
API availability and MediaCapabilities predictions do not certify performance, stability or the complete physical GPU specification.
Start with the likely path, then retest.
