Misc/Uncategorized
– The pace car has been switched to a Mustang. The Solstice pace car is still there for older replays.
– Allow SoftTH 2.0 DLL (pre-release version) to load without causing a loading error.
– More cars can be transmitted to clients due to improved compression techniques.
– Added in a ticker bar when spectating with the UI hidden (you can hide the UI with the space bar). You can enable the tickers in the app.ini [Overlay] EnableTicker=1
– Throttle should no longer cause motor to rev up unexpectedly if you haven’t moved any controls yet like sometimes happens with Logitech wheels/pedals.
– Splits/delta key is now a mappable control in the Options screen, default behavior is the TAB key.
Graphical Updates
– Added support for night lighting at Richmond.
– Improved illumination levels at most of the tracks. The main difference is that the dark sides of objects are darker with shadows disabled.
Cameras/Replays
– Force TV cameras to set damping and ‘aim at group’ to on.
– Added in control to FF/RW to next incident in a race with ctrl-NUMPAD1 and ctrl-NUMPAD3.
– New hot key ‘/<num><enter>’ focuses cameras based on running order, similar to the ‘*<num><enter>’ hot key, so /1<enter> focuses on the car in first place.
In-sim Text Chat
– Pressing ‘r’ from either the driving screen or the session screen responds to the last person who private messaged you.
– Improved driver name matching for chat private message targets: /<driver> message.
– <driver> can be: <name>, or #<car number>, or just <car number>
– Name represents the beginning portion of a name so bob matches on bob or bobby.
– You can string together multiple names using ‘.’ to replace spaces so b.brown could match ‘bob brown’.
– Names must be specified sufficiently to give a unique result.
– If two names conflict but one is an exact match than that name is used. This is so bob.brown and bobby.brown can be differentiated.
– The # symbol is optional to help make things faster.
– New chat target: /rc <message> sends a message to the admins of current event. (/rc is short for race control)
– New chat target for admins: /all <message> sends a chat message to all drivers even if chat is disabled.
– Spectators can text chat with each other but not with drivers. This includes spectators that are administrators. In order for an administrative spectator to chat with the drivers they must use either the /<driver> or /rc or /all commands. Or an administrator can allow spectators to chat with drivers using the !spchat command.
– Added in support for administrative race control chat commands, type !help for a complete list of commands. (You must be an iRacing official or the owner of a hosted session)
Administrative Chat Commands
– Some commands may be shortened, the bolded part of the commands are the shortest form acceptable.
– <> means a required parameter.
– [] means an optional parameter.
– <driver> is the name or number of a driver, same as described above.
– [message] is an optional message to be appended to any admin command.
eg: the command ‘!remove #32 Banning for reckless driving.’ would send out the notification: ‘#32 was removed from the system. Banning for reckless driving.’ to all drivers.
!help [command]
!? [command]
– Print list of commands available, or list additional information about individual commands.
– So ‘!help admin’ would output detailed help about the admin command.
!admin <driver> [message]
– Give other drivers admin privileges.
!nadmin <driver> [message]
– Remove admin privileges from driver.
!remove <driver> [message]
– Permanently remove a driver from the race, can remove spectators as well.
!yellow [message]
– Throw a yellow if not already active, issue during 1 to go, to extend the caution.
!waveby <driver> [message]
– Move car up to next lap and send to the end of the pace line.

Fixed Setup Events
– The ability to run fixed-setup races has been added in this build. Fixed-setup hosted sessions can be created. Some regular iRacing series also use fixed-setups, and will be so designated.
Fixed-setup iRacing series and Hosted Races must specify a race setup. This setup will be available for use during testing*, practice, time trial, and race sessions. A separate qualifying setup may also be specified. The qualifying setup will be available during testing*, practice and qualify sessions. If a separate qualifying setup is not specified, the race setup will be used during qualifying.
*When the sim is started using the “Test Car on Track” button on the Race panel for a fixed-setup series, the testing session will be fixed-setup, and will allow use of only the race setup and qualifying setup (if specified) for the current race week in the series.
The system will ensure that only the correct car setups (race and/or qualifying) are available during each session of an event. For example, during the practice session of a hosted race, both the race and qualifying setups will be available for use, but during the race session only the race setup will be available. If both the race and qualifying setups are available during a session, the race setup will be selected by default. The Garage screen can be used to select which setup (race or qualifying) to apply to the car. The car settings can also be viewed on the garage screen, exported, and saved locally for future use.
The car setups used in fixed-setup sessions must reside on iRacing’s servers so that the race servers can load them and distribute them to all of the drivers in a race. When setting up a hosted race, you will have the ability to upload the car setup(s) you wish to use. Once uploaded, those setups will be availble to you to use in any future hosted sessions you create. The car setups that iRacing distributes with the cars will be available on our servers so that you may use them in your hosted sessions.
When setting up a hosted race, you may designate that the race will be fixed-setup. For a fixed-setup hosted race, you must choose a race setup for each car that is allowed in the session. If the hosted race includes a qualifying session, you may, but are not required to, specify a qualifying setup for any of the cars allowed in the session.
– Steering ratio is adjustable in fixed setup events for cars that have this adjustment. Nothing else is adjustable in any way during a fixed setup event.
Race Panel
– The Race Panel now supports session selection across event types. So from the race panel you will be able to register for the next race, time trial, qualify or open practice directly from the race panel.
– There has been some confusion regarding the “Cannot Change Car” button/message on the race panel. This error message has been misleading because it would be displayed for multiple different error conditions. Examples being the session is full or the registration period has ended. The error reporting should now be accurate.
Test Panel
– The Test Panel has a “Night Lighting” option on Tracks for which this option is available.
Spectating Sessions
We have added the ability to join a race session as a spectator. You can select a race to watch from three places. There is a new page under Events – Spectator Events that presents a list of all currently active race, open practice and hosted sessions that are available for watching. You can also select a race to watch from the myRacing – myRacers page (more on that in the online status section below). Finally, you can use the new myRacers popup (more on this in the online status section below) that is available just to the left of your iRating in the top right section of the user interface in the members site.
There are a limited number of spectator slots for each race session. When you register as a spectator you will see a “Watch” button appear in the race panel where you would normally see the “Join” button. When you click the “Watch” button you will launch into the sim where you can watch the race and communicate with other spectators. You do not need to have your driving peripherals configured in order to watch a race.
Online Status
– We have added new functionality to help you to determine what your friends / studied / searched for drivers are doing on the service and to easily join their race session or join as a spectator.
This new information is available in two places. First of all we have completely reworked the myRacing – myRacers page. This page now displays a sortable table showing your friend / studied racers along with checkboxes to filter the display. There is an online/offline indicator. If the indicator is green it means that the member has been online within the last 2 hours. If the indicator is red we will display the time of their last login. If a member is currently registered for a session you will see details of their session. If the session is joinable for either racing or watching you can do so from this page.
In order to implement this feature with acceptable performance we now limit your number of friends and studied to be a maximum of 50 each.
– A new myRacers popup is always available just to the left of your iRating towards the top right of the members site UI. A label dynamically updates to display a total of how many of your friends + studied racers are currently online. Mousing over this label will display a list of your online drivers. An icon to the left of each driver’s helmet will indicate if you can join their session either as a driver or spectator.
– There is a new setting on the general tab of the settings panel that enables you to hide your online status from other members. At this time this is a simple toggle on/off. If you decide to hide your status, people who have you on their friends or studied list or search for your information will see “Member information is private” next to your name on the “My racers” page.
– There is a new label beneath the iRacing logo on the top left of the member’s site UI that dynamically updates to display the total number of unique iRacers who have been online in the last 2 hours.
Hosted Sessions
– In some cases we were removing hosted sessions from the page when the session was full rather than just showing a “Full” button. This was confusing to members because a session would disappear from the screen well before the registration period ended.
– When a hosted session was full we wouldn’t allow people to re-enter the session who already had a pit assigned. The problem case is as follows: Join a hosted session and withdraw, wait for the session to fill up completely, if you now tried to get back in it would fail because no pits are available. The correct behavior is to allow you back in because you already have a pit assigned to you. This should be working properly now.
Transmission and Shifting Model
We have replaced our model of a car’s transmission and how the driver causes the car to shift gears. Previously, clicking out of a gear or into another gear would instantly do just that – regardless of whether or not such a gear change was actually physically possible.
Now, your shifting inputs tell the sim what you’re trying to do, and the sim tries to do what you ask – the sim no longer instantly just shifts. Think of your shifting inputs as telling the sim, “I am pushing/pulling on the shift lever.” You will often need to hold the shift control for little while as the shift goes through to completion before releasing, if you let go too early the sim will interpret that as you letting go of the shift before the shift completes, probably leaving you hanging in neutral. If you use an h-pattern shifter, then the shifter is automatically holding the next gear which makes it more comfortable.
This is likely to require some time to adjust to, so do not be afraid of turning on the auto-clutch and auto-blip shift aids when you need reliable shifting while you’re still learning to feel out shifting with lower levels of aids in practice and testing.
The currently engaged gear will not disengage unless the transmission is sufficiently unloaded:
– For upshifts, full throttle will definitely hold the current gear engaged. You will need to lift, use the clutch, or hit the rev limiter to unload the transmission enough for the current gear to disengage.
– For downshifts, engine braking when fully off-throttle especially at higher rpm may well be sufficient to prevent the current gear from releasing. You will likely need to use a little bit of throttle (which will happen anyway if you are blipping on downshifts), or use the clutch to disengage the current gear. If you are braking while holding down some throttle it will quite likely be too much throttle to allow the current gear to disengage, unless you use the clutch to unload the transmission.
If you are using an h-pattern shifter control to shift with, moving the stick into neutral will ask the sim to try to leave the current gear if it can. Selecting the next gear will tell the sim to attempt to engage that gear once it succeeds in getting into neutral. If you are using sequential controls to shift with, holding down the shift button is equivalent to pushing on the shift lever to the next gear. If you let go of the button before the shift completes, you may not have even left the current gear yet, or may end up in a neutral between the two gears.
Cars that have a sequential transmission can no longer be shifted with an h-pattern shifter. If you have your h-pattern set as the preferred shifting method, the sim will give you a warning message when you first get into a sequential car to start driving advising you that you will have to use your configured sequential controls.
If you try to engage the next gear when the rpms are too mismatched, the gears will just grind and the next gear will not engage. So that means that smash-it-into-1st race starts don’t work any more, as trying to grab 1st at high rpm is not healthy for the gearbox and you will hear nasty grinding sounds. You’ll want to engage 1st gear while the motor is not revved up and the clutch is pushed in (the anti-stall clutch conveniently holds the clutch in for you if you are stopped and not revving the motor). Then you do a race start via revving up the motor with the clutch pushed in, and doing some kind of clutch drop. If you use the auto-clutch shift aid, it will hold the clutch in for you while you are revving in neutral, so selecting 1st gear for your launch is acceptable. The auto-clutch shift aid will release the clutch for you, but with a fractional delay.
For a dog-box transmission, the next gear can typically engage when the revs are within a few thousand rpm – a pretty broad rpm range. You don’t need to bother with the clutch, just appropriate throttle lifts or blips to disengage the previous gear are all it takes to shift. This also means that you can quite comfortably left foot brake with dog-box cars.
– Upshifts you want to do as fast as possible: press and hold your upshift a moment before you lift to preload the shifter, then do the fastest lift you can for a really quick shift. It is possible to use the rev limiter to unload the transmission and cause the upshift instead of lifting. If you are using sequential controls, remember to press and hold the upshift button until the gear change finishes. Some race cars have a built in throttle cut that engages when it detects pressure on the gear lever. For these cars you don’t need to lift at all, just clicking the button will trigger the throttle cut. But make sure not to release too rapidly, or the shift may not be fully completed as you release pressure from the shift lever.
– Downshifts can be done very quickly too. Press and hold your downshift a moment before you blip to preload the shifter, then tap the throttle for a blip of the motor to minimize upsetting the car’s balance as the next gear engages. In most cars there will be enough engine braking torque that the gear won’t disengage until you tap the throttle for the blip, and remember to press and hold the downshift button until the gear change finishes.
For the Solstice and other cars with synchromesh gears, the synchros do all the work when the revs are mismatched. You won’t hear a grind when you select the next gear while the synchros are doing their thing, so the neutral timing isn’t the same as a crash box. You don’t absolutely have to use a clutch for a synchro box – but the synchros are not even remotely close to being strong enough to overcome the entire motor when trying to rev match so you have to get the entire motor to match the correct rpms for the next gear yourself, but if you use a clutch pedal then the synchros can easily match the transmission input shaft for you and make shifting a much faster and reliable experience.
When shifting with a real synchromesh gearbox, you engage the next gear’s synchros by lightly pulling the stick against the next gear, until the gear clicks into place. Unfortunately, the sim has no ability to know that you’re trying to select the next gear until you actually select the next gear, and only then can the sim start working the simulated synchros. With sequential controls, the sim knows you are trying for the next gear up or down, so you just need to press and hold the shift button until the gear engages. With an h-pattern you need to actually click your next gear into place quite quickly so the sim can start pushing it’s simulated shifter against that gear’s synchro. The timing of the shifting process feels a little different to a real car. You’ll have to get used to the timing of your shift request but continuing to hold the clutch in until the gear finally engages before letting the clutch out, unlike in a real car where you can feel the shifter clicking into place as the gear finally engages.
– Upshifts you typically want to do as fast as possible, but it’s not as fast as a dog-box transmission can do it: press and hold your upshift a moment before you lift to preload the shifter, then lift the throttle while pushing in the clutch. As the next gear engages, you can push the throttle down again and release the clutch. You could also choose to not lift, and just push in the clutch pedal until the next gear engages. This method of power shifting will not make your clutch want to be friends with you for very long. Or you could not use the clutch at all, but you have to lift off the throttle and wait for what will feel like forever and ever until the engine drops enough rpm for the next gear to engage. Remember to hold the shift button until the gear shift completes.
– Downshifts you will also want to shift as quickly as you can, to start working the next gear’s synchro. Press and hold your downshift a moment before you blip to preload the shifter while braking with your right foot, then press the clutch pedal in with your left foot and roll your right foot somehow to blip the throttle while maintaining smooth brake pressure at the same time, and when the next gear catches, release the clutch pedal smoothly. This is called heel-toe downshifting, and it’s very hard to get a good feel for in the sim due to not being able to physically feel the response of the car and the shift lever. It is possible to left foot brake and not use the clutch on downshifts, but it’s hard work on the synchros and you must make sure to blip the engine rpm well enough to match revs or you’ll be stuck in neutral fishing for a gear. Remember to hold the shift button until the gear shift completes.
Sometimes if you mis-time your synchromesh gear shifts (particular if you don’t use a clutch) you can clear the synchro but still miss the gear engagement, and you will hear nasty grinding sounds from your gearbox.
Some of the higher end race cars with sequential gearboxes can have fully automated shifting. You just bang the shifter button and it does whatever it needs to do with the throttle to get the next gear for you in a very short amount of time.
Here is a list of the cars we currently have and the type of transmission they have so you know what style of shifting you will want to use with each:
Fully automated sequential:
– Dallara
– Jetta TDI
Dog-box sequential with throttle cut:
– Corvette C6R
– Ford V8SC
– Radical SR8
– Riley DP
– Star Mazda
Dog-box sequential:
– Legends Ford34C
– Skip Barber
Dog-box h-pattern:
– Impala A
– Impala B
– Latemodel
– Lotus 79
– Silver Crown
– Silverado
– SK Modified
Synchromesh h-pattern:
– Mustang FR500S
– Solstice
– Spec Racer Ford
Key points:
– If you are struggling to adapt to shifting with no shift aids, don’t be afraid to turn on the auto-clutch shift aid and perhaps even the auto-blip shift aid for important sessions where you need reliable shifting. Like any physical activity you may have been doing for a long time it can take a while to unlearn your old muscle memory habits and learn new ones.
– Sequential cars will not allow the use of h-pattern controls, like the Jetta has been doing for a while now.
– Remember to think “press and hold” for sequential shift buttons until the shift is complete, it’s not just “click”.
– Practice your timing so you press and hold the shift button before you blip on downshifts or lift on downshifts.
