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.

v1.55.1.0 Setup without CUDA - 30 June 2025
v1.55.1.0 Update without CUDA (If you already have installed v1.36.6.0 Setup without CUDA or newer)

- Replaced the club name/logo by the flag name/logo on the timing and the dashboard pages. Note that you can change the logo size on the dashboard by changing the font size value.
- Fixed a bug that could make JRT to crash.
- Fixed a bug where the relative gap was not displayed when your car speed was very slow.
- When the gap with the leader in the overall standing has not been calculated yet by JRT, it displays the iRacing value.
- Updated the 'tank capacity', 'refuel speed', 'pit time lost for changing tires' and 'conso ratio' default values used by JRT to estimate the laps remaining for the others classes in multiclass races. Some wrong values could cause some predictions to be inaccurate, especially when the "extra lap" was closed.
- Fixed a bug with the launcher page where the new dashboard3 and dashboard4 pages could not be removed.
