  1. Latest Build Update rFactor 2 - 1.1114 Now Available! Steam Build IDs client: 4122083 dedi: 4124026 Note: Admins must update all dedicated servers Release of Build 1114 Releasing a new rFactor 2 build is typically something we do with a classic bulleted changelog, but this time we felt it deserved a bit more than that. During our recent rF24 event, technical issues cropped up that left us no alternative but to red flag the race. We decided to immediately regroup and redirect our priorities towards dissecting and fixing what turned out to be long standing issues. It was not a simple task, but we rolled up our collective sleeves and dug in. With a lot of help of the participating teams, we analyzed all the problems and for the first time were able to reproduce most of them. Their cause turned out to be very specific edge cases in ‘rejoins’ and ‘driver swaps’ so we proceeded by focusing on trying to break these features in as many different ways as possible. So of course, much of the findings relied on intense and focused testing over the past weeks. Having to go back and test multiple scenarios repeatedly and working to find fixes and workarounds required a well-thought-out approach with a solid understanding of the issues from all involved, both on the testing side and the development side. This intense focus has given us an insight into the many ways things can go wrong in the heat of racing. Thankfully, we also had the massive support of the rFactor 2 community through post-race feedback and stories, as well as logging – this was invaluable and an enormous push to help find the root cause of many of these issues people have in online events. As a team, we meticulously went over each of these reports and looked for any specific details that could point us in the right direction. Car Selection and Upgrades One of the main areas we focused on was issues related to rejoining after getting disconnected during a session, for example when the network connection goes down for a moment. rFactor 2 has always allowed for a driver to rejoin a race after a computer crash or network issue, but in some cases on rejoining the server, the driver would end up with a DNF (Did not finish), a DQ (disqualification) or their name would show at the bottom of the list as simply ‘pending an open session’. Of course, these outcomes are incorrect and the question for us was: what triggers these scenarios? Our research and testing quickly showed that, in most cases, these issues were related to rejoining and either a) picking a totally different car from the car selection, b) picking the right car with the wrong livery from the car selection, or c) picking the right car and livery but with a different upgrade package. You might ask, “Why is this a problem, I always pick the correct options”? Whilst that might be true in 99% of the cases, it’s the 1% that hurts us here in the end. It’s hard to be sure a team of multiple drivers always chooses the correct options. Making a mistake, it turns out, causes problems for more people than the driver rejoining, so we needed to make sure this could no longer happen. To tackle this problem, we first looked at the core code of the rejoin process to make sure all options regarding car and upgrades are inherited and stay with each driver, regardless of disconnections or previous driver swaps. This means when you join with car A and upgrade X, it will be logged in a more robust way that prevents the driver history getting lost. Next, we worked on making this process more user friendly, so that it’s actually impossible to make a mistake on rejoin. We enhanced the network protocol to communicate to your client what car, livery and upgrades were used before, so we can choose the right car for you. For example, if you join with a ‘BMW M8 GTE’ with the ‘Le Mans package’ and ‘my-team-livery’, and you have a network issue during the race and are booted, instead of seeing the whole list of cars, team liveries, and upgrades on rejoin, you only see your BMW M8 GTE, and the option to change upgrade package is no longer available. You simply get your car back! This brings us to another important point and side effect of rejoin errors. Rejoining with the wrong car or upgrade would often cause lags and freezes for all other drivers already on the server as everyone was forced to load a different car in real-time while on track (instead of the car that got parked in the garage when you disconnected). “AI Take Over” and Driver Names Stuck in the Pit Menu A recurring issue we’ve seen is when a driver swap takes place, the AI would suddenly take over the car without warning. This was caused by trying to hand over the car to a team mate that was no longer a passenger or even on the server at the moment of the pit stop. By default rFactor 2 was then configured to let the AI take over. This turned out to be a bad idea and we altered the code to no longer do this. This means that from now on, if the driver taking over is no longer present, you will retain the car at the end of the pit stop. This will allow you to keep racing and retry a driver swap with your team mate without AI taking over and ruining your race. When selecting a driver in the pit menu, names of any passengers would stay stuck in the list and would be select-able regardless of whether they had left the server or stopped riding with you. This meant you select your team mate in the pit menu, they leave the server or stop riding with you, but their name stays in the pit menu and can be selected. This caused multiple issues: On disconnection/rejoin you would often end up with a DNF, and if a name of a driver was selected that was no longer riding or had left the server, the AI would take over. We’ve fixed this issue by simply removing any drivers from the pit menu list that are no longer riding with you (as should have been the case all along). Disconnection/Rejoin with Passenger(s) Disconnections while another driver is riding along, either waiting on a driver swap or having just completed one, would end in a DNF on rejoin. For example, you’re driving on track, your team mate is riding with you and you get a disconnection. On rejoin, you’re not able to race again and your team mate’s name is now showing in the list as a driver with a DNF. We fixed this by making sure that on disconnect/rejoin only the current driver retains the car, all other teammates simply stay registered as ‘passengers’ and are not considered a driver until an actual driver swap takes place. Pit Menu Parameters Locked After Rejoin Yet another issue we looked at and were able to fix was the sudden inability to toggle pit menu options after rejoining. This was particularly a problem if you experienced a disconnect with very little fuel and could not request more fuel in the subsequent pit stop, ultimately you would run out of fuel and end the race with a DNF. All allowed in-car pit menu options should now be open to selection on rejoin. Steam Integration Improvements As part of our ongoing profiling process based on logs sent to us by users, we have also discovered that the “real-time” API functions that Steam provides could cause small hiccups. We technically solved that by internalizing the original plugin and making sure we execute such functions on a background thread so they can never interfere with our physics loop. This change is done both client and server-side and it means you will no longer see a SteamPlugin.DLL in your plugins folder (and we’ve made sure that if it is still there by accident, it gets ignored from this build onwards). Faster Loading Times Last but not least, we also spent some time profiling and optimizing the track and car loading process. Internal tests have shown improvements in the range of 30-50%, which should help people in general. Faster loading obviously also means you can rejoin quicker, losing less time overall. What’s next? Build 1114 is the first of two scheduled releases to address the issues we found. We decided to split the process in two, concentrating on the major bugs first and then addressing the smaller ones. We thought it was important to get an update into everybody’s hands as quickly as possible, but only after making sure we could not break this build anymore. As always we encourage people to update both their dedicated servers and clients and report any issues. We are heavily committed to getting this right and continue to improve the online experience in rFactor 2. We expect to have an update on those issues next month, but again, we’ll take as much time as we need to ensure these minor issues are also completely gone.

  5. Roadmap Update July 2019 Roadmap-time is one of the best times of the month, even for us! You wonder why? It gives us the chance to bring together what we worked on, admire screenshots, or just be happy about what we achieved as a team in terms of improvements, new features or content. As we´re developing and working on rFactor 2 basically 24/7, it´s important to also enjoy every little step that we did to make this simulation better. Because in the end, we´re sim racing enthusiasts, just like you! Alright alright, enough romantic talking about game development, let´s go down to what’s actually happening outside of our continuing work on Nordschleife, UI and the competition system. And yes, it has it all, further improvements, new features and fresh content. 3..2..1.. GO! A New Future Ever heard that 3 is the magic number? That´s basically what happened here. Take the knowledge and technology of McLaren (1), mix it with the heritage and meaning of the name Senna (2) and add the GTR (3) badge to deliver a masterpiece. Voilá, introducing the hottest carbon fibre thingy on rubber tyres that mankind has ever tried to tame on track. Powered by a 4.0 litre twin-turbo V8, this almost demonic piece of joy can skyrocket you onto the first place of nearly any grid around the world. But the McLaren Senna GTR is not just the track-day car that would be outside most people’s budgets, it’s more than that. It’s our chance as a simulation studio to actually try to have a look into the not-so-distant future and create something that could be the pinnacle of the next-gen sports car racing world. So be aware, if you unleash this beast, you might time travel! Talking about time travel, the McLaren Senna GTR will be released within the next few weeks. One could think that with this announcement, we burned up everything we have, especially since 2019 is already half-way through. But we can assure you, that’s absolutely not the case! There is so much more still to come this year! And yes, this means that we will also add more rubber tyre thingys that go fast! Worlds Fastest Gamer 2 We’re super stoked to be supporting Worlds Fastest Gamer again with an incredible prize! Next week, rFactor 2 drivers will have the chance to qualify for the World’s Fastest Gamer Grand Final via an online time trial run on the Sebring International Raceway course with the Aston Martin GT3, running from August 5 to 18. The top 20 racers will then do battle in a live-streamed, 40-minute race on August 24th. In addition to earning the chance to chase the full-time real-world racing stint worth more than US$1 million, a US$10,000 prize pool will be up for grabs in the final race. Incredible stuff!! The winning rFactor 2 driver will join eight racers hand-picked by the World’s Fastest Gamer judging panel plus the winner of the Gear.Club mobile game time trial. Look out for more details soon. In the meantime, check out the WFG website http://wfgamer.com/ Competition heats up! While we’re at it, let´s also announce an esports live event with Porsche! Yes, the company that makes all the great race cars we admire. We can´t say more yet, but don´t worry. As soon as the lollipop man lifts, we’re ready to launch more info onto the pitlane. That’s not all, McLaren Shadow kicks off again soon. We will bring you more news on that shortly! Technical Update A little under four weeks ago, we hosted the rF24, an endurance race with many high-profile teams and drivers participating at Le Mans. Roughly half-way through we had to red flag the event because of technical issues. Immediately after the event, we released an official statement and started gathering information from all the participants and set out to try and fix these issues with a special task force. It’s time for an update now. In the months leading up to the event, we were already investigating and improving issues some people were having with the physics calculations “freezing”. In investigating that issue, we built a very detailed “stopwatch” system that we could use internally to exactly pinpoint where these delays occurred. We learned a lot from the “logs” that our community submitted and found multiple issues. For one, our timing, code that had been part of rFactor 2 and many ISI-based sims before, turned out not to be the most efficient and reliable way to run something at 400 Hz (and 2400 Hz for the tyres). We rewrote that code, and after several stages of testing these revisions made it into the release. A second issue we discovered had to do with plugins that were taking too much time. We give plugin authors a lot of power, running plugins directly as part of the physics thread, but as you know, with great power comes great responsibility, and unfortunately in some cases, plugins don’t behave nicely. We’ve blacklisted a few plugins and are talking to authors to help them improve. A third issue was in how we sometimes talked to Steam, which has led us to rewrite that code and convert it from a plugin to internal code. We are still diagnosing more rare issues, and there is a forum thread that explains how you can submit your logs for review. Now during the event, we ran into issues that have plagued us before, but never this severely and never in a way that we could reproduce. However, we now had so many people reporting issues that we started to see some patterns, so the first step we took was to analyze exactly what had happened. We took our time, collected a lot of data from participants, for which we are very grateful, and then started to try to reproduce specific problems. The first issue we could reproduce were join lags. Someone would (re)join the server, and this issue then propagated to all other clients. We discovered that this would happen whenever someone rejoined the server using a car with different upgrades from the ones he used before (such as forgetting to select the low downforce upgrade). Our first fix was to add code that would not propagate such (wrong) upgrades to other clients. We then quickly confirmed that these join lags were indeed gone, which was a big improvement since these were causing all kinds of other issues as well. When exploring this first issue, we discovered that it was currently possible to rejoin not just with the wrong upgrades, but even with the wrong livery or even the wrong car, and this was not handled correctly in the code. We saw this cause issues where you ended up with the wrong set of physics because of the upgrades and the server re-applying the same setup you had before, but to a different car. We also saw issues where a car would appear in the garage for some, but on the road for others, and a few other variations that were all caused by the same problem. We decided to solve this in two places. First of all, we now double check when you rejoin that you indeed have exactly the same car, livery and upgrades again. If you don’t, rather than letting it cause problems, the server will boot you and tell you why it did so. Secondly, we added code to the client that, when you connect to a server, will check if your intention is to rejoin. If it is, the server will now tell you directly which car, livery and upgrades to use, and we will simply show you that car in the UI instead of letting you choose anything. We also decided to make the rejoin check a bit more lenient in that you still need to rejoin with the same driver, but this driver is now identified via his Steam ID, meaning that in the case of a hardware failure, if you have multiple installs of rFactor 2, you can even take over on a different client and resume the race. Another, slightly unrelated, issue we looked into was loading times. The good news here is we’ve found some improvements and our upcoming release will roughly halve those loading times. We’ve seen numbers being reported by testers indicating a 40-50% improvement. Other issues still on our “fix list” are a somewhat smaller lag some people are getting when someone leaves the server as well as a few usability issues, such as the fact that if you got a disconnect right before you made a pitstop, you basically get a car with no fuel when you rejoin, and you have to try and drive a lap first (which will likely fail). Right now our intention is to release the first of a series of updates as soon as this rejoin process is “bullet proof”. We are going through a series of tests, each with a bigger set of users, until finally we are confident that we squashed this. Our current estimate is that this first update will go live sometime next week. We won’t stop there, and remain committed to making sure everybody has a good experience racing rFactor 2. Of course, we will also do a re-run of the rF24 when we feel these issues have all been resolved and tested. Simexpo We’re looking forward to once again attending Sim Expo this year at the Nürburgring, as usual with a few surprises up our sleeves! Make sure you come and visit us and say hi!
