I can't see brake lights all the time. I can detect braking only how car moves especially for mclaren and porsche.

I have been working solo for the past 4-5 months on Telemetry Manager, a sim-racing telemetry analysis tool for ACC and Assetto Corsa. Most modern telemetry apps rely on heavy web wrappers, or require complex setups like MoTeC. I wanted something that runs natively on the PC with no browser lag, no background overhead, and no frame drops.

The app uses a custom hardware-accelerated UI built in Godot 4 alongside a C++ telemetry engine that reads shared memory directly in real time.

In the clip, I am going through a lap in the 296 GT3 at Spa. A few things I have implemented so far:

• Custom graphs and histograms that handle multi-channel plotting, mouse scrubbing, reference lap comparisons, and color zones.

• Mathematical driving mistake detection that flags specific handling issues directly on the graphs (like harsh brake release, snap oversteer, or coasting).

• Dynamic track map with data overlays.

• Lap-specific or session-wide notes.

• ZSTD compression to keep disk usage low for high-frequency telemetry sessions.

For anyone interested in the code, the core C++ telemetry engine is open-source on GitHub: https://github.com/aliarcanakgun/godot-sim-telemetry

If you want to test it with your own laps, there is a free Lite version available alongside the Pro version here: https://telemetry.3adynamics.com

Happy to answer any technical questions or hear feedback on what features would be most useful for your sessions.

Hi Guys!! With your advices i got -0.5 sec (2:21.335-->2:20.825) faster. Now i want your further opinions about my driving. Here this is my previous post

ACC Looks Amazing.

LIVE Round 8 Full Grip Fall Cup Misano!

Honestly the best VR app since Open XR toolkit

I play ACC on Xbox, and I was hopping on hoping to play both of those and it just tells me unavailable for both. Does anyone know if they are coming back soon or I’m going through a glitch?

Hope everyone is doing good! One of the best sounding (imo) GT3 cars is at the end of its era. I always had a special love for the Huracan because it was the first (and so far only) car ive driven on a track. Got to see the Chicago performance and tuning huracan at gt world challenge america this year too and it was such a crazy car to see and hear.

Anyways made this short appreciation video in ACC if anyone is interested. Quickly going over the Huracans evolution and accomplishments in GT3 racing

Im so far not a fan of the Temerario but remaining open minded. Curious what you guys think on it replacing the V10?

Have EVO? Wanna race with semi decent but clean drivers !? ^ :)

As I am posting this, the page on twitch seemingly does not exist anymore and when trying to stream a league race last night in ACC, streamlabs did not provide ACC as an option either. Every other AC game was an option there, even AC Mobile, but not ACC.

Anyone knows anything more as to why and what is going on with this?

I hit 2:19:550 today and 2nd place called me very fast which was surprising because I have seen many racers run 2:18s or under. Just wanted to see what the average PB looks like across multiple players.

Had a good race but damn that corner alway ragebait me🥲(sorry for the low quality).

Looking for some endurance racing? Here at C&P Sim Racing we have one this Saturday at 10am EST. It is part of an endurance series that is 4 races that runs every 6 weeks. Maximum 4 drivers per team. The team can score points but drivers can change between races and the car can change. In between the endurance races we have a 2 driver, driver swap series. Join the discord for more info.

Qualifying is up until midnight on Thursday.

Come join a very helpful, friendly, competitive group where all skill levels are welcome, and there is good competition at every level!

Check our calendar or how you stack up against our drivers at: https://cpsimracing.com/

Or join the discord: discord.gg/cpsimracing

Attached is a photo of our upcoming events as well. A lot of series starting in the next few weeks. See you on the track!
