Real YUKFUE Share My Score card with before and after benchmark scores — A real Share My Score export from YUKFUE 6.40.0. Results shown are a sample, not a universal performance claim.

Benchmark proof

Don’t trust our numbers. Measure your own.

Run the built-in benchmark before and after your changes to compare responsiveness signals on your own PC. Scores can move between runs, so YUKFUE includes a variance margin and treats changes within the noise as the same.

No universal FPS promise. Different systems, games, settings, and starting points produce different results.

Trust before tweaks

Built to show its work

The product is designed around proof, clear choices, and a way back — including clear labels when an action cannot be automatically undone.

Honest

The before-and-after benchmark accounts for normal run-to-run variance instead of turning every wobble into a win.

Compare Free and PRO

Reversible

Original settings are backed up before supported tweaks run. Restore Center handles undo, while rare one-way actions are labeled clearly.

Review the safety approach

Restore Center

Know what changed. Keep a way back.

YUKFUE records original settings before supported tweaks are applied, then lists applied changes in Restore Center so they can be reverted individually. Rare actions that cannot be auto-restored are marked ONE-WAY before you decide.

No snake oil

Optimization without the magic act.

YUKFUE does not promise the same gain on every PC. It gives you measurable before-and-after checks, explains the Free and PRO split, backs up supported changes, and labels the exceptions. You keep the final say.
