Ever had a level’s frame rate slump and no idea why? Was it a HISM-heavy foliage pass, a landscape material with too many texture samples, or three stationary lights stacked on the same shadow channel? Usually finding out means tabbing between half a dozen stat commands and squinting at an on-screen HUD.
I built Level Benchmark to turn that into one button.
Run it against your currently loaded level and get back a single readable report. Every mesh’s triangle count, LOD count, material count, texture resolution, collision and Nanite state (instanced/foliage meshes counted at their real effective cost, not per-instance); every light’s type, mobility, shadow-casting state, and overlaps that could blow your shadow channel budget; real GPU pass timing, shader complexity, and overdraw sampled directly from PIE and cross-referenced back into one table, so you know exactly which actor to open.
What it checks
- Static analysis (no PIE): tri count, LOD count, material count, max texture resolution, collision, Nanite state, ISM/HISM-aware effective triangle counts.
- Landscape scan: component count, quad count, Nanite state per proxy.
- Light scan: type, mobility, radius, shadow casting, overlap detection, and stationary shadow-cluster warnings (the 4-light shadow channel limit).
- Material cost ranking, linked back to the meshes using them.
- Estimated texture memory: real measured GPU size, deduplicated per unique texture.
- GPU pass timing, shader complexity, and overdraw (PIE), with a per-pass breakdown.
- Per-light GPU cost (optional): isolates each shadow-casting light’s actual cost by toggling it and measuring the diff.
- Run comparison against a previous CSV export, plus CSV export for spreadsheet/CI tracking.
- Toolbar, Tools menu, Window menu, and console commands for headless/automated runs.
Requirements: UE 5.7 or 5.8, Windows (built and tested on Windows), editor-only and adds nothing to packaged builds
Built for solo devs and small teams without a dedicated technical artist watching frame time all day
