Rennsport’s fourth patch adds replay, multiplayer and Praga fixes

Sim racing game Rennsport has today, 11th December 2025, released its fourth major post-launch patch.

The update, Version 1.1.7, is available across all platforms, with some notable claimed changes.

Chiefly, the safety car (used for rolling stars in some event types) has been disabled for multiplayer events. Traxion experienced it to sometimes lose all control of its facilities online, and this has been switched off “until it learns how to behave.”

Smart move, let’s hope this can be remedied sometime early in 2026.

Elsewhere, the Praga R1 was noted as being a bit of a pig to drive – it now has new tyres and a revised setup. We’ll see if this is an improvement next time we boot Rennsport. Perhaps pertinently, outside of bugs, this (on paper) seems to be the first notable dynamics-focused tweak of late.

The replays have been beset with odd bugs, so there’s another suite of fixes here. You can now also rejoin an online contest (ranked race) during practice and qualifying sections of the event. Work continues on the single-player AI performance, now said to follow the driving line with greater accuracy.

The full changelog is below. This is expected to be the final update for 2025, with the creation team now aiming for further changes next year, including a bigger release in February that will include classic endurance race cars and the Le Mans track as DLC.

Rennsport Version 1.1.7 patch notes

Cars

• Praga R1 have new tyres and a tweaked set-up

Crashes

• Fixed multiple game crashes related to the pit crew

AI

• Fixed an issue with the Porsche Mission R where the AI did not go full throttle on parts of tracks with banking
• Fixed an edge case that allowed AI cars that are DNF & DNS to set laptimes when the session is already over
• Fixed an issue where AI drivers sometimes received a valid finishing lap time when the stage ended even if they were still in the middle of their lap
• Smoothed the target point for AI drivers, allowing them to follow the drive line better when no other cars are around
• Adjusted AI behaviour to prevent them from insistently approaching the drive line during the first part of grid starts

Championships

• Fixed a bug where championship progress failed to update when clicking “Finish Round” and skips the reward screen too quickly

Consoles

• Fixed an issue where if you have both a gamepad and a steering wheel plugged in, when the gamepad went to sleep, it would show a pop-up message that your gamepad disconnected (Sometimes in very unfortunate moments during a race)
• Updated default bindings to address feedback from the community that the ignition input was being activated by mistake

MFD

• Updated the MFD to have both forward and backward navigation

Pit Stops

• Fixed an issue with the Ford Mustang GT3 that the fuel cap was on the wrong side resulting in weird snapping from the pit crew 

Settings

• Fixed an issue where Anti-Aliasing settings were not always saved

Official Contests

• Added a rejoin button which will allow you to rejoin the contest if it’s still in the Practice or Qualification stage. If you rejoin while the contest is in Qualification stage, you’ll be sent to the pits and able to spectate the remaining session but you’ll be able to race as normal once the Race stage starts. Rejoining is not possible during the Race stage.

Spectator/Replay

• Readded a button that was missing to allow you to tilt the camera when in Free Camera mode
• Added a “Live” button for live replays which will jump to the latest point in the replay
• Fixed an issue where spectator visibility bindings for managing the spectator overlay were not working

Safety Car

• The safety car has been temporarily disabled in online contests until it learns how to behave
