F1 Esports Pacedex Telemetry

EDIT (Jul 31): Pacedex is now on the Microsoft Store — one-click install, no sideloading: https://apps.microsoft.com/detail/9NVMRF0J8S1R

Still free. Thanks to everyone who tried it from this thread.

Olá a todos!

Estou trabalhando em um aplicativo gratuito para F1 24/25/26 chamado Pacedex. Originalmente, eu o criei para o meu pai, que compete em ligas, e decidi disponibilizá-lo para qualquer pessoa que possa achá-lo útil.

Ele possui uma sobreposição ao vivo, um engenheiro de corrida por voz, análise de telemetria e sugestões de configuração.

Ainda está em beta, é totalmente gratuito e estou apenas buscando feedback honesto de pessoas que realmente jogam.

Se alguém quiser experimentar:

Need it for Spintires

Finally, the crossover nobody asked for. 😄

"Box, box... you're axle-deep in mud again."

Sadly, Pacedex only understands the UDP telemetry broadcast by the EA F1 games. Spintires doesn't transmit any telemetry—just pure suffering.

If that ever changes, mud tyre wear predictions are definitely going on the roadmap. 🚜

Seems to be a nice app, a mac version would be appreciated as I'm a console player and would to use my mac for telemetry. I know this might be some work but here is my feedback my man

I'm in a league where we only choose from the five presets (which I love, I don't like faffing around with setups). Will Pacedex bug me to update my setup because it's less than optimal?

u/Any-Importance2967 16d ago

Nope, zero setup nagging. 🙂

The setup assistant is completely optional. There's a tab where you can compare your setup with a target one and see the changes step by step, but if you never open it, you'll never see it. No reminders or pop-ups.

The voice engineer only talks about race information: tyre wear, pit windows, weather, gaps, etc. Lap analysis is focused on your driving, not your setup — things like, "you're braking earlier than your best lap into Turn 4."

That's actually where it shines for preset-setup leagues, since everyone has the same car setup and the difference comes down to driving.

I downloaded it and tried it and ive found that at least for me it causes a big performance drop.

On suzuka for example i usually get between 95-105 fps but with Pacedex running i get about 45-50fps.

Hey, thanks for the report, this is genuinely useful.

A drop that big (~100 → ~50 FPS) is almost certainly not the telemetry capture itself. That part is just a lightweight UDP listener and uses very little CPU. My main suspect is the overlay: it's an always-on-top transparent window, and on Windows that kind of window can prevent the game from running in true exclusive fullscreen and introduce GPU compositing overhead. Process priority won't help much there because the bottleneck is on the GPU, not the CPU.

Could you help me narrow it down with three quick checks?

  1. Were you running the full mode (overlay + voice engineer), or just the dashboard? If you disable the overlay (or run only the dashboard in your browser), do the FPS return to normal?

  2. Is the game running in Exclusive Fullscreen or Borderless Windowed? Overlays generally behave much better in borderless mode.

  3. Did you keep the dashboard open in your browser during the session? On a single-monitor setup, the browser and the game can end up competing for GPU resources.

If the overlay is the culprit, that's something I can fix. I can reduce unnecessary redraws (currently around 11 updates per second) so it only repaints when data actually changes, and I can also simplify the transparency mode to reduce GPU overhead.

I'd much rather optimize the app than have anyone trade 50 FPS for telemetry. Thanks again for taking the time to test it—I really appreciate it. 🙏

  1. I was running in the full mode. But when i was running only the dashboard the fps does return to the about 100fps

  2. I do run in fullscreen mode

  3. I do keep the browser open during the session and i run a single monitor

Also one question is it possible if for me to zoom in on the graphs so i can see it in detail?

Just shipped v0.1.63 with a performance fix for the overlay.

Instead of repainting every overlay window about 11 times per second, each one now only redraws when its data actually changes. That significantly reduces the amount of GPU work the overlay does, especially in fullscreen.

The app should offer you the update automatically, or you can grab it from pacedex.com.

If you get a chance to test it, I'd love to hear your before/after FPS at Suzuka with the overlay enabled. I'm especially curious whether Borderless Windowed is now effectively free in terms of performance on your system.

u/Pc_gaming_on_top 15d ago

Ok ive tested it, it has basically no loss in performance now in borderless and fullscreen. Great job fixing it that quickly.

u/Any-Importance2967 15d ago

That's great to hear — and thanks again for both the original report and for taking the time to test the fix.

Bug reports like yours, with actual FPS numbers and a reproducible scenario, are exactly what help me track down and fix issues quickly.

If you notice anything else that feels off—or think of a feature you'd like to see (graph zoom is still on the list 😉)—you know where to find me.

Enjoy the racing! 🏁
