# HyperFrames v0.7.78

Released on 2026-07-28.

Windows renders on a hardware GPU now use drawElement fast capture, which was previously macOS-only — roughly 2× faster capture on the same safety net (per-frame self-verification with automatic screenshot fallback), covering about 78% of Windows renders. Render telemetry also gains GPU-backend and laptop power-state fields so performance can be diagnosed per machine rather than per platform.

## Features

- **Engine:** drawElement fast capture now runs on Windows with a hardware GPU (previously macOS-only); Linux/software-GPU hosts are unchanged ([cb30157eb](https://github.com/heygen-com/hyperframes/commit/cb30157ebbbcfedd3606b9d566d565f4412de45e))
- **Producer:** The parallel-drawElement router (still opt-in via `HF_DE_PARALLEL_ROUTER`) now engages from 700 frames instead of 2000, and renders report `on_battery` / `low_power_mode` ([3da31e399](https://github.com/heygen-com/hyperframes/commit/3da31e399b498d0ab6b1ce32b008b8b10cdcd2dc))

## Fixes

- **CLI:** Persist authoring skill in hyperframes.json for durable render attribution ([d287e5244](https://github.com/heygen-com/hyperframes/commit/d287e5244c1e6d9051642f94f368ef7a1e26bd34), [#2762](https://github.com/heygen-com/hyperframes/pull/2762))
- **Producer:** Installs with telemetry disabled no longer spawn `pmset` while building render events, and the parallel-drawElement router no longer pins a worker count on renders where its streaming path can't run (compositions over the streaming duration cap) ([b99c80389](https://github.com/heygen-com/hyperframes/commit/b99c8038983e2c0bb2545e8eaf5fcd7c4f9abe03))
- **Engine:** `gpu_renderer` telemetry reports a low-cardinality backend/vendor bucket rather than the raw driver string, and is attached to failed renders as well as successful ones ([4520cd240](https://github.com/heygen-com/hyperframes/commit/4520cd240b9a4ac20f77e6a2e8204866e549fd35))
- **Producer:** Validate distributed video metadata ([557d82b6a](https://github.com/heygen-com/hyperframes/commit/557d82b6a9547e403598713e2840c41736d35544), [#2839](https://github.com/heygen-com/hyperframes/pull/2839))
- **Studio:** Harden preview recovery ([c62bd4c45](https://github.com/heygen-com/hyperframes/commit/c62bd4c454d7a53aac39e03b10da8eeb2a93d77e))
- **Studio:** Improve preview loading reliability ([18b9acac1](https://github.com/heygen-com/hyperframes/commit/18b9acac12269899b0bfacb289d9bde3e1b065e4))
