LA Coliseum Makes Its Debut in iRacing

LA Coliseum Makes Its Debut in iRacing.jpg
The second patch for iRacing in 2022 has dropped – and with it, a new track joins the sim’s roster: The short oval at the LA Coliseum, which has been developed in cooperation with NASCAR, is now available to SimRacers. Also, the patch promises graphics-related latency improvements as well as multiple smaller fixes for various tracks and vehicles.

Ovals, even of the short track variant, are nothing iRacing is lacking. However, the LA Coliseum is still special – the quarter-mile oval premieres virtually even before the real-life counterpart sees racing action! NASCAR’s Busch Light Clash is set to take place there on February 6th, a yearly exhibition race of the top stock car championship. So far, it has taken place at Daytona International Speedway, but moves from Florida to California now. iRacing and NASCAR have been working closely together to create the track both virtually and in real life. As a result, sim racers can now race there even before the professional drivers do.

To the enjoyment of many – though probably a few days late – the track improvements of the patch mean, among other things, the removal of the sausage curb on the exit of the Bus Stop Cicane. The curb had caused sim racers a lot of headache because of broken suspensions during the Daytona 24 and the weeks leading up to it. Before the actual 24, it has been removed for the IMSA race on relatively short notice, meaning iRacing could not react in time. Now, the service has made up for it.

Also, NVIDIA Reflex support is now on board, which promises improvements regarding graphics-related latency issues. You can find the complete patch notes down below.

  • NVIDIA Reflex support has been enabled. When enabled in the Graphics options (on the top right), and when the Simulator is GPU-bound, this option reduces Simulator to render latency by enabling low latency mode in the device driver. When enabled with “boost mode” it also keeps the GPU clock rate higher when the Simulator is CPU-bound, which can help a little bit too. Enabling NVIDIA Reflex in the Graphics Options can help reduce this latency, mainly when the Simulator is GPU-bound. When CPU-bound, there is not much Reflex can do.
  • An additional graphics-related system meter, named "T" has been added to the user interface. The T-Meter measures the total frame time from when the renderer started generating the frame until the GPU completed drawing it. It is not the same as the R + G timer, because the CPU queues frames to the GPU and they can pile up, also the GPU is running in parallel with the CPU. The maximum pre-rendered frame widgets are hidden when Reflex is enabled, since it takes over and keeps it near zero.
  • The NVIDIA Reflex option is disabled by default if the GPU/driver does not support it.

  • A new setting, “[SPCC] textDurationFactor=1” has been added to the app.ini file. This value is the multiple for the length of time spotter text messages are displayed on the screen (ie: a value of 2 leaves spotter messages on the screen twice as long as the default value of 1).

  • TrueForce support has been temporarily disabled while we await a patch to GHUB. All Logitech G923 users will need to recalibrate their steering. If desired, you can manually turn TrueForce support back on by manually editing the “app.ini” file and setting “[Force Feedback] trueForceEnabledForcedOff=1”.
  • Reworked Logitech TrueForce support so users will no longer need to recalibrate after the system is enabled/disabled. That’s right! This is hopefully the last time you’ll be forced to recalibrate by an update!

Los Angeles Memorial Coliseum
The Los Angeles Memorial Coliseum, a short asphalt oval, is now available for purchase and racing!
More than 100 years ago, one of the United States’ most iconic sporting venues was commissioned as a memorial to veterans of World War I. Since then, the Los Angeles Memorial Coliseum has hosted just about every event imaginable, from the Summer Olympics (three times as of 2028, which will become a record for any facility at that time) to the Super Bowl, and has served as the home stadium for numerous professional and college sports teams in football, baseball, soccer, and rugby. The stadium has even hosted dozens of major off-road motorsport events, with trucks and cars jumping in and out of the Coliseum entrance every lap.
In 2022, NASCAR became the latest major league sport to join the venue’s legacy with the Busch Light Clash at the Coliseum. A quarter-mile circuit constructed within stadium walls will see the annual preseason all-star race of the NASCAR Cup Series leave Daytona for the first time. The track was designed and tested by iRacing in cooperation with NASCAR in advance of the unique event, with top real-world and sim racing pros all logging countless laps before both its release on iRacing and real-world debut. The change in venue also leads to a change in format, with qualifying heats to build the feature grid in a manner similar to a local short track race.
Now’s your chance to take the wheel in a unique part of NASCAR history in one of America’s most iconic sporting venues. See if you’ve got what it takes to conquer the Coliseum quarter mile!
Add the Los Angeles Memorial Coliseum to your iRacing landscape by purchasing it from the iRacing store here:

Nürburgring Combined
  • The rolling start grid has been moved back to the gantry on the straight to mitigate issues with proper spacing on starts with multi-class Sessions.

From the folks that brought you the gem that is known as the Roval, Nascar that is.
I don't really care for the La Coliseum track but I do like the edition of Nvidia Reflex to help reduce latency.

Here's a quick summary of this past weekend Daytona 24hrs which had an insane amount of teams and participants!

Looking forward to Yannik's write-up on his experience.

Don't need this track i already have Wreckfest

I don't need wreckfest as I'm stuck in iracing oval rookie hell.

They need a new rank called Pork-Chop for some of the morons creating mayhem.

or maybe crank the price up to discourage them from participating
That is very cool! Hopefully iRacing could add more bullrings accross USA and maybe Late Model cars
I would probably race on the Coliseum track if it was free but pay for a track that is a recipe for constant yellow flags.?No chance.Martinsville Nascar races are most;y run under yellows with so many racers trying to win in the early laps.
