Use when an Unreal Engine 5.8 project misses its frame rate or stutters: "optimize to 60 fps", "we run at 38 fps", CPU or GPU bound, game or render thread too long, hitches, traversal or shader stutter (PSO), GC spikes, camera-cut spikes, Lumen, Nanite, VSM, ray tracing, foliage, crowds or Niagara too expensive, async compute, stat unit, ProfileGPU, Unreal Insights, TraceQuery, snapshothitches, scalability and device profiles, dynamic resolution and TSR, streaming budgets, or proving a fix…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Performance engineering in Unreal Engine 5.8 Expert level here means milliseconds per stage, not frames per second: classify the bound with one honest capture, explain the worst frame by the thread that works rather than the one that waits, fix in the order of measured size, and prove the result with repeated runs on the same route and build, hitches judged apart from the average. The performance engineer owns measurement, diagnosis and proof; most fixes go back to the teammate who owns the content. If a sibling skill named here is missing from your available skills, ask the user to install it (`npx skills add scenario-labs/skills --skill <name>`); unattended, proceed from tool schemas and flag the gap. **REQUIRED BACKGROUND:** scenario-unreal-expert (channels, review loop, 5.8 traps). **Status (2026-09-24):** [`scripts/ue_perf.py`](scripts/ue_perf.py) is **not yet run in Unreal**; its pure layers pass `tests/code/unreal-performance/run_all.sh` (50 offline tests on synthetic captures). Every UE name is [verify]; first run: `job_probe_perf.py` (procedures P0). ## Stance (the expert delta) …

How to install
mdr add scenario-labs/skills/scenario-unreal-performance@sha256:ec439becdbdce78fThe line at the top of this page pins the label git:20260926.9ac7861, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
