[LIVE @ 18:30 UTC] Cornering speed / Physics update

Tomorrow, we will be rolling out an update to address the cornering speeds in the simulator.

The current situation was a technical limitation / restriction placed into the system at a prior date, not intended or by design. Previously, I had to work within this limitation but I have discovered a way to bypass it and get back realistic cornering speeds.

This will not require an app update and can be seamlessly rolled out to the live service tomorrow.

I expect to have the service fully over to the new system by about noon tomorrow. Races from that point onwards should notice the difference.

UPDATE: New physics are now live.

Both will receive the improvement, as it's the simulator itself. As for the sync issues, that will need further investigation. That sounds more like desync or network related.

FYI we have confirmation from testers that the experience in 3D and 2D is significantly improved. Looking forward to rolling this out tomorrow.

Running some final tests then I will need to re-export all the data for the simulation to the service, roll it out across servers.

I have identified an issue unrelated to this update where on some tracks cars are slowing on the start/finish line. I'm looking into whether I can resolve that with this update too. Hopefully it won't be more than a few hours before the update goes live. I'll keep you posted in this thread.

A quick update, I have identified what's wrong with some tracks. The bit that's taking time is recompiling, testing, fixing, recompiling, testing. Still confident of going live today.

The service meanwhile is running through a single server that frankly is overloaded, so if you are experiencing lag that is why. The situation should be temporary. I'm going as quickly as I can to get physics up for peak hours and hopefully address these issues with tracks too.

Okay! I finally got there. I've managed to fix the start/finish line issues as well, where cars were slowing down.

It'll take me 30-60 minutes to roll this out to the live service. I think you will all be pleasantly surprised at how much smoother this is. It makes even iGP 2025 look a bit jittery.

New Physics are now Live

You will really notice the difference on tracks like Singapore, but everywhere in general should be smoother, faster and more flowing according to the racing line. A new physics model was developed for this and in terms of car movement it should even be an improvement over iGP Manager 2025.

Tyre balancing

The update will likely introduce some tyre balancing challenges and we may have to adjust their performance, as they were developed using the old physics, so please pay extra attention to tyres tonight and give us your feedback on the balance. I've wiped all practice laps in the last 25 minutes.

Start/finish issues on tracks like Europe

These should be resolved but please report any quirky behaviours around this and I'll investigate deeper.

It does seem related, unfortunately. I can see CPU usage spiking on the servers and I've identified a cause. It's not the physics, it's a caching system on disk (always cache issues!). I'm working on redundancy for the sims against this now. Hopefully, this will resolve this for the next race.

Today has been one of those days.

There were serious server problems tonight that make it impossible to judge the update. The CPU usage on some of our servers shot up to 100% and they were basically unable to run normally. If you want to see it properly and your league race was impacted tonight, I'd recommend trying a sprint race.

I have identified a cause of the fault. It was all the simulators fighting over temporary cached files on disk, and getting stuck in an infinite loop. I'm adding in redundancy against this now and have already taken the impacted servers out of circulation while I upgrade them.



This looks like something else, like a misalignment of the 2D map and the 3D data. I'll pass this along to our Unity devs, thank you. You can see they are performing actions offset by something like 100-200m from where you would expect.

There is no ctrl+z undo option for migrating a service at this scale. Also, in case you can't tell, I'm running the entire service on my own right now. This is not easy. I'm: Managing servers, upgrading C++ code, writing PHP code, talking to all of you. Everything. Alone. All day. 24/7. I barely stop to eat. I'm doing the best I can, and certainly not sitting here relaxing about the situation.

I can appreciate when things don't "just work" you have every right to complain, just bear in mind this is not EA sports you are talking to. It's literally one guy working from his home office. The constraints I'm having to work with here are making it really hard to keep track of all the different things going on at once. This is certainly pushing the new tools I have to their limits, and I'm learning these limits on the job right now.

I'm going to try and regroup, get everything in order tonight, and hopefully we come back stronger tomorrow. Today was... a mess.

I can only apologise for it being a public spectacle that is impacting your games and leagues. I do appreciate the patience most of you have shown, thanks again.
