WARNING :
- The CUDA version works only with old Nvidia cards and is not compatible from the Nvidia RTX3000 cards.
- When you install a new version, you don't need to uninstall the old one. You won't lose your settings.
- Each time you install a new version, you may need to delete the cache of your browser and restart it.
- Before updating JRT, check that your JRT update license doesn't expire before the date indication in orange above the version you are about to download.

NOTE : CUDA is only used for a specific setting of the photo mode and works only with old Nvidia cards. If you don't need it, it's better to install the version without CUDA that is lighter.

- Fixed a bug when using the spotter arrows mode where the background and the rules were not hidden.

v1.57.0.0 Setup without CUDA - 15 December 2025
v1.57.0.0 Update without CUDA (If you already have installed v1.36.6.0 Setup without CUDA or newer)

- Added a new spotter mode that displays rectangles instead of arrows to represent the cars. There is colors options that allow you to show the rectangles with different colors depending if the other cars are in the slower/same/faster class, a lap down/the same lap/a lap ahead, or ahead/on the side/behind. You can also see your pit box and the distance to it. You can see if there is a slow car far ahead, and if your are slow, you can see the cars coming behind. And finally, for the Oval drivers, you can display if you have a car to pass/let pass when a yellow is out.
- If you are an administrator of a host session, you should now see the correct drivers incidents on the timing.
Added a filter so in this case, you can filter the incidents for the selected driver or for all the drivers.
- Now when you do a pit stop, JRT calculates the distance to your pit box and save the data in a pitBox_ldp_data.json file in 'My Documents/Joel Real Timing/trackmaps' so the next time you pit, the distance to your pit box will be correct. Without doing that, depending of the tracks, the distance can be erratic because the data sent by iRacing is correct only when you are on the race track, and not on the pit lane.
This new data is used to improve the pit box countdown in the JRT speech options, or the pit box distance displayed on the dashboard and on the visual spotter.
- Added a countdown offset value in seconds for the pit box countdown option in the JRT speech options.
- Amplified the sounds files and transformed the mono files to stereo because that could cause some issues depending of your sound system. If you want those files to be edited on your JRT configuration you will have to delete the "My Documents/Joel Real Timing/sounds" folder and to restart JRT.
- Fixed a bug caused by the iRacing update that inverted the TC and TC2 settings for the BMW lmdh, the Cadillac GTP, the Porsche GTP and the Ferrari 499P.
- Added the new cars and tracks.
