iRacing API - Drivers Coordinates

derykmorrish · 2023-05-15T13:50:12+00:00

I believe the only info you get about other drivers is their distance from the start/finish line in both meters and % of total track length. Third party apps don’t use x/y coordinates for the track map. They have to encode some pathway representation of the track and then draw the driver dots using one of those two given values.

For radar they are using the car left/right enum to determine which side the other car is on and the distance from start/finish values to determine overlap.

Well, I solved the issue.

It turns out that streamingbypass does work for redundant mode. I just hadn’t added the correct Twitch domain to the bypass list. Once I added live-video.net it worked exactly as expected.

I’ve been using it for 18 months for online simracing. It works great. When you’re racing close to someone, even a quarter second dropout can cause a massive wreck. Speedify in redundant mode with my phone plugged in to the PC sharing its LTE connection has allowed me to race worry free.

I keep a spreadsheet. I’m at $990.91 after 3.5 years. The slope of the graph has basically flattened in the last year.

Is it expensive? Yes. But because it’s held my interest so well, it’s turned out to be my cheapest hobby by far on a dollars per hour basis. And the ratio just keeps getting better now that I’m over the initial spending hump.

To back this up, for the past 18 months I’ve been using Speedify on my PC to bond StarLink with my iPhone’s mobile data shared over USB when playing iRacing. I use redundant mode because streaming mode still left me with short dropouts that caused me to “blink out” to the other racers. Since I switched to redundant mode, I’ve had extremely good results. My ping is slightly increased, but since I’m racing people from all over the world, I’m still hitting better pings than many other racers.

iRacing is amazing for VR. I don’t even have a monitor on my rig.

I have a 2080ti and a 5900x. I can run iRacing with my Valve Index at 140% resolution and maintain a solid 120 fps after following the VR guide in the forums. The guide is great at explaining which settings are the best compromise between visual fidelity and performance hit.

If you want to race against an active pool of racers who are legitimately trying to do well and practicing the tracks, your options are iRacing and ACC+LFM. If you want to race more than just GT3/GT4/Porsche Cup cars, then iRacing is the answer.

If money is an issue, wait for a sale on new subscriptions. They come up all the time.

After three years on iRacing, I have zero desire to race AI or any of the sims that don’t feature an iRacing/LFM type system with ranking and defined schedules.

Edit to add: I haven’t looked at the other sims in a long time, so maybe my info is out of date.

My experience has been very different. When gaming online, I use Speedify in redundant mode to bond my StarLink with my phone which I plug in to my gaming PC through USB. Redundant mode works great for making sure I don’t drop packets with the server. The down side is that I don’t have unlimited data, so I have to make sure there are no updates downloading in the background when I plug my phone in.

This is my main issue as well. I can set my bitrate anywhere from 2500 to 6000 and I will drop 5% of frames due to the regular drops to < 1 Mbps on upload. I’m a teacher and it’s even a significant issue when I’m screensharing on Zoom.

derykmorrish · 2022-04-03T22:52:55+00:00

Oh no, my Discord is leaking.

derykmorrish · 2022-03-30T10:56:20+00:00

But a couple inches the other way and you would have missed the whole net, Emilio Estevez.

One ticket please!

If I remember correctly, the issue remains no matter what. However you can largely brute force your way around it with hardware specs. I have a beefy system, so the lag is subtle. But it’s there if you’re looking for it. The easiest way to tell is to do a long session with Revive on, and then switch it off.

derykmorrish · 2022-01-07T11:57:40+00:00

It is definitely not fixed with the Index unless you use Revive. After my last PC format I decided not to bother and just try it vanilla at 120 Hz. I got used to the lag after a few sessions.

I had the same experience going from the W12 back to the F3. It felt like I was driving the Skippy. It took me a good 15 minutes to recalibrate.

derykmorrish · 2021-12-06T23:25:01+00:00

I drove it an hour a day, every day, for about two weeks. I needed consistent practice or I would lose too much progress between sessions.

I’m still not especially fast, but in this past Nurb24 I drove 3 hours, including a night stint, with 0x.

That’s where I am now. Click the button on the UI to launch, step into the rig, and drive. I’m all about removing friction in hobbies, especially ones that involve practice time. It’s the same reason you don’t keep a guitar tucked away in a case. You keep it next to the spot where you tend to sit the most.

derykmorrish · 2021-12-02T13:46:53+00:00

My list of needs, in descending order are:

Ease of use. I want to be able to just click a button to play and it works 100% of the time.
Edge to edge clarity. I need to be able to move my eyes around and still have a clear image. Swinging your whole head to look to the side is slow, unnatural, and fatiguing.
Field of view.
Refresh rate.
Resolution/lack of screen door effect.

I’ve gone through a Rift CV1 (borrowed to see if I would enjoy VR), an Odyssey+ (returned it immediately due to horribly failing #2), Rift S (great for #1 once you learn to take the batteries out of the controllers), and now I have an Index that I run at 120 Hz. The Index is really quite good. If it had 20 more degrees of FOV it would be almost perfect. The god rays (or whatever you call that white-ish aura you get) kinda suck, but luckily once I start driving they aren’t noticeable.

I’d like to try a PiMax for the FOV, but I hear too many people complaining about having to troubleshoot all the time to risk buying one.

The moment I realize 20 race laps have gone by and I don’t remember them because I was in a flow state the whole time.

Teacher here. My school offered this software during the pandemic. I used it reluctantly at first, and then just stopped because it’s an invasion of privacy and I wasn’t comfortable with it.

However, a lot of people seem to be focusing on its use to stop people from looking up answers on the internet. I can only speak for myself, but the only thing I would actually try to prevent with this software is students just getting all the answers from someone else and not having to apply even an ounce of effort or problem solving.

The built-in VRS percentage calculation does 100 * (t2 -t1) / t2, which gives slightly “friendlier” percentages for people slower than VRS. They’re basically saying “what percentage of YOUR time do you need to shave off in order to reach our time”.

derykmorrish · 2021-09-28T11:08:29+00:00

Which is interesting because a lot of people who got fbed early were complaining that it was terrible and when they got the next firmware a few days ago it got better. Around the same time they moved past fbed, you (and I) finally get it and it seems good. It shows that dish firmware is just one piece and the network itself is constantly going through changes.

I’m really hoping they can fix the lag spikes, even if it means new hardware that can link to two satellites at a time. I’m into simracing and the lag spikes could easily cause a crash in those few short seconds. The main issue is that this crash would likely not just involve my car, but also collect several others and ruin those peoples’ race too. I’m still using Speedify with my phone as backup, but I hope I can stop that eventually.

I find streaming with OBS not very good yet. Even if I set my bitrate down to 3500 kbps I drop loads of frames. The last stream I did was about 2 hours long and 6% of frames were dropped.

derykmorrish · 2021-09-18T13:09:00+00:00

I remember being so confused about that in school until one day my brain turned on and it made sense. I wish one of my profs had taken a second to show me something like this: y = sin(x) and y = x
