Measured, not promised.

AVX Tune backs up your Microsoft Flight Simulator settings, measures what a change actually does on your PC, and tells you honestly whether it helped. If it didn't, one click puts everything back.

Protect

1. Snapshots your UserCfg.opt and control bindings before anything changes
2. One-click restore, with a safety snapshot taken before every restore
3. Sim Update watcher: spots when an update resets your settings and shows a key-by-key "what changed" list so you can put them back

Measure

1. A/B testing with Intel PresentMon 2.6 (included): fly the same short circuit before and after one change
2. Compares 1% lows, average FPS and time spent above 33 ms
3. Gives a clear verdict: Keep, Roll back or Inconclusive, judged against your own PC's noise floor

Tune, Health and Clean

1. Hardware-tier presets and settings editor (beta), which only writes menu values observed in real settings files
2. Read-only health checks: free space, GPU and VRAM, page file, HAGS, Memory Integrity
3. Conservative cache cleaner with an allow-list and confirmation
4. Redacted support report you choose whether to send

What it doesn't do

1. No FPS promises. A "no improvement" result means the tool did its job.
2. Never touches sim memory, injects code or installs drivers
3. Only writes files while the sim is closed, after a snapshot
4. Works alongside AutoFPS, AeroTune and Lossless Scaling

Pairs with AVX Sorter: Sorter organises your add-ons, Tune measures your settings. Sorter can hand its flight loadout straight to Tune.
