FAQ & Best Practices

Q: Profile vs Analyze? Profile is instant stat/visualization toggles (no scan). Analyze scans the current level and returns a ranked list of problems with fix guidance.

Q: Is it safe? Yes. Editor-only. Perfector never modifies assets.

Q: Will this improve FPS? Perfector itself doesn’t run at runtime. The fixes you make based on its findings typically do improve runtime performance since all projects generally does have something to report.

Q: Does it require Nanite/Lumen? No, but it’s tuned for common UE5 workflows. Checks adapt based on project features.

Q: How often should I run Analyze? At the start of a level, before handing off to lighting, and before submissions. For large worlds, run per sub-level.

Q: Known limitations

• Very large worlds: scan time increases with actor count, use folder/level filters.

Troubleshooting

Nothing shows in Results

• Check Setup → ensure at least one check enabled.

• Confirm you’re scanning a loaded level (WP cells need to be loaded).

Stat toggles don’t appear

• Ensure you’re in Profile and not hidden behind other panels.

• Some stat overlays are mutually exclusive; toggle off other views.

Scan is slow

• Limit Folder scope.

• Disable categories you don’t need.

• Exclude streaming levels that aren’t relevant.
