PerfCheck is an editor-only Unreal Engine tool that scans your project for common static performance risk patterns and turns them into a clear, actionable report.

It helps you spot things like oversized textures, missing LODs, dense meshes that may benefit from Nanite, high material slot counts, heavy lighting setups, complex collision, crowded maps, and other content patterns that often cause projects to become harder to optimize later.

PerfCheck is built for solo developers, small teams, technical artists, QA workflows, and marketplace sellers who want a fast project health check without setting up a full profiling session first.

The workflow is simple:

Choose a preset, run a scan, review your Performance Risk Score, inspect the findings, adjust rules if needed, scan again, compare results, and export a clean report for yourself, your team, or your clients.

Every finding shows what was detected, the value that triggered it, the rule threshold, why it matters, and a practical recommendation for what to review next.

PerfCheck is not a runtime profiler. It does not measure FPS or frame time, and it does not promise automatic performance gains. It is a static risk scanner designed to help you find common warning signs earlier and make better cleanup decisions.

PerfCheck never modifies, optimizes, deletes, uploads, or transmits your project data. It runs entirely inside the Unreal Editor, has no runtime impact, uses no networking, and stores history and reports locally.

• Static performance risk scanning for Unreal Engine projects

• Clear Performance Risk Score with per-category breakdowns

• Texture checks for large textures, 8K usage, and non-power-of-two dimensions

• Static mesh checks for missing LODs and dense meshes

• Nanite suggestion checks for suitable high-density meshes

• Material checks for high material slot counts and map-level material usage

• Lighting checks for shadow-casting and movable light counts

• Collision checks for complex-as-simple and missing simple collision

• Map and actor checks for high actor counts and Blueprint actor counts

• Findings table with search, filters, details, and clear guidance

• Ignore and unignore findings without changing assets or maps

• Local scan history with before/after comparison

• Markdown, CSV, HTML, and PDF report export

• Click-to-focus and open assets or maps where supported

• Editor-only C++ plugin with no runtime impact

• Supports Unreal Engine 5.5, 5.6, 5.7, and 5.8

PerfCheck performs static project analysis. It highlights common risk patterns, recommendations, and warnings based on editable rules.

It does not measure runtime FPS, frame time, GPU cost, platform performance, or final shipping performance. Always verify final performance with Unreal Insights, platform tools, packaged builds, and real target hardware.

PerfCheck does not automatically fix or optimize assets. All cleanup decisions stay in your control.
