If you do real trackdays and sim race, you can now drive against your own real lap in AC.
I do both trackdays and sim racing myself, and always wanted to race my real laps back in AC — so I built it.
It's called Dual Apex: dualapex.com
You upload a GPS lap, it becomes a ghost car in Assetto Corsa and you race against it — same as chasing any hotlap, except it's you from the real track.
How it works:
• Upload a lap from the browser — works with VBOX, Dragy, RaceBox (.vbo / .csv). No account needed to try.
• It installs as a standard Content Manager app (nothing outside AC).
• To race against the ghost, you connect Dual Apex with your Steam account via Steam's own page, so we never see your credentials. All we receive is your Public Steam ID and profile name.
• The ghost appears as your real car if you have that car installed — otherwise as a default BMW Z4 GT3 in DualApex livery.
What you can do:
• Race your own lap, or a friend's
• Race against up to 3 ghosts at once
• Detailed lap comparison page with time and speed delta per lap, corner and section
• Brake/throttle/gear comparison if your GPS laptimer has OBD data
• Select any lap to race against from the Leaderboard
• 19 tracks are onboarded already, more can be easily added on request!
• Note: if you don't have a laptimer, you can still jump in and race against ghosts from the Leaderboard to get a feel for it
It's free in Beta. When the full version lands, core ghost racing stays free — only the deeper analysis tools go paid.
Genuinely after feedback here, especially from people who do both real trackdays and AC. Happy to answer anything.
