A free AI health check for your flight simulator

Because average FPS hides the thing you actually feel. A stutter is a single long frame, and the usual causes are a VRAM ceiling, a terrain or object detail setting set higher than your card can stream, a stale shader cache after a sim update, an add-on conflict, or a drive too full to cache scenery. They look identical from the pilot’s seat and need opposite fixes, which is the whole reason for reading the machine instead of guessing.

You can ask, but on its own ChatGPT knows nothing about your machine. Not your GPU or how much VRAM it has, not which driver you are on, not your terrain and object detail settings, and not the add-ons in your Community folder. So it answers from generic forum advice, and you can end up changing settings that were never the problem.

That is the gap the Hub fills. Every run writes an AI-ready text file to your Desktop with the information you chose to collect already gathered and scrubbed — attach it to ChatGPT, Claude or Gemini and now the answers can take your setup into account. That path is free and needs no account. The FSC written report adds a summary, findings with supporting evidence, and suggested next steps. Your first one is free; after that it’s part of FSC Pro.

Microsoft Flight Simulator 2020 and 2024 (Microsoft Store or Steam) and X-Plane 11 and 12. The diagnostic reads the installation off your PC rather than talking to a running sim, so the sim doesn’t have to be open — the exception is the optional live performance capture, which needs you to be flying.

Hardware and driver details, display configuration, Windows settings that affect performance, your simulator settings and add-on list, and controller bindings. FSC Pro can also collect recent crash evidence and an optional live performance snapshot. Every optional category has a tick box. Before the package is created, the collector removes Windows user names inside file paths, email addresses, and Wi-Fi or network names. A file it cannot scrub is left out; if an unsafe file cannot be removed, no package is created. The result is a plain text file on your Desktop that you can inspect. Nothing reaches FSC unless you choose to send it.

Not to run the diagnostic or to use the file yourself. You need one for us to write the report, because the report has to be delivered somewhere private. Creating it takes an email address and a password: press Get my free report in the Hub, choose New User in the sign-in window that opens, and register.

Yes — one full written report per account, no card needed. It’s written by a lighter AI model than FSC Pro uses. FSC Pro includes six reports per rolling 12 months, written by a more powerful AI model, for $5 a month. The free diagnostic file itself never runs out.

An analysis can identify likely problems, show the supporting evidence, and suggest what to try next — you make the changes. It can help with things a machine can observe, such as mismatched settings, old drivers, full drives, possible add-on conflicts, and, with FSC Pro’s crash-log collection, recurring crash patterns. It can’t reproduce a fault that only happens once a week, and no report can promise that one change fixes everything. If you’d rather have a person do it with you, our sim techs work through it live in a one-to-one session.

Not currently — FSC Hub is Windows 10 and 11, 64-bit. It installs to your own user account and doesn’t change system files.
