League of Legends Highlight Capture Fails on Intel Arc A770 (Driver 32.0.101.8626) — Auto Recording

young26 — Sun, 05 Apr 2026 15:37:14 GMT

🔹 Environment

OS: Windows 11
CPU: Intel Core i5-13600KF
GPU: Intel Arc A770
Driver: 32.0.101.8626
Game: League of Legends
Platform: WeGame

🔹 Summary

The automatic highlight recording feature (a.k.a. “Hero Moments”) in League of Legends is completely non-functional on Arc A770.

This is not an intermittent failure — the feature never works.

🔹 Observed Behavior

No highlight capture during gameplay
Post-match highlight generation always fails
Error message shown:

“Failed to generate highlight video… (disk / cmd.exe / service checks)”

These generic checks are not relevant to the actual failure condition.

🔹 Expected Behavior

Event-based recording (kills, assists, etc.) should trigger capture
Highlight video should be generated post-match

🔹 What’s Already Ruled Out

This is not a basic system misconfiguration:

Disk space ✔ sufficient
C:\Windows\System32\cmd.exe ✔ present and functional
System integrity ✔ verified via SFC / DISM
Background services ✔ normal
Game client ✔ reinstalled
Driver ✔ clean installed

🔹 Key Observation (Important)

Manual recording via OBS Studio works fine
Encoding pipeline (QSV / AV1 / HEVC) is clearly functional

👉 So this is NOT an encoding failure

🔹 Likely Failure Point

This strongly points to a capture trigger / hook failure, not encoding:

Possible areas:

DX11 hook compatibility (LoL is DX11-based)
Event-triggered capture pipeline not firing on Arc
Incompatibility with legacy highlight system (likely built around NVENC assumptions)
Arc driver not exposing expected interfaces for “instant replay”-style capture

🔹 Repro Steps

Launch League of Legends
Play any match
Finish match
Observe: no highlight generated

Repro rate: 100%

🔹 Impact

Feature is effectively dead on Arc platform
No fallback, no partial functionality
User-facing error message is misleading and wastes debugging time

🔹 Additional Notes (Blunt but Useful)

This looks like a systematic compatibility gap, not a one-off bug
The error message suggests generic Windows issues, but the actual failure is likely in:
- GPU capture API compatibility
- or driver-level support for event-based recording

👉 From a user perspective, this comes across as:
“Feature exists, but silently unsupported on Arc”

🔹 Request

Confirm whether automatic highlight capture is officially supported on Intel Arc GPUs
If supported:
- Identify why event-triggered capture fails
If not supported:
- This should be explicitly documented (currently it is not)

🔹 Suggested Direction

Validate Arc behavior against:
- DX11 hook-based capture
- Instant replay / rolling buffer triggers
Compare with NVIDIA NVENC-based workflows (likely baseline assumption in LoL ecosystem)
