TSW5 – Post Release Patch 18 – Update Summary

Here is a summary of Patch Notes for the update being pushed today, 23rd June 2025.
This update brings a huge range of improvements, including the new Köln-Aachen timetable for PS5 and Epic Games players, and the first stage of our core memory optimisation improvements.
It may take up to 24 hours for the patch to become available on your systems.

Memory Updates:

Following on from our continued discussions around performance and memory, we’ve been able to make minor improvements to performance over the course of our monthly updates, but alongside the patch we’re sharing today, we’re making a significant next step, the first of a two-part release, to improve the robustness and stability of the core game by further reduce crashing, with the intention of ensuring game sessions can be enjoyed and completed.
Our testing for this patch has shown success in reducing crashes, and additionally, some members of our beta team have reported anecdotal improvements to framerates and smoothness. Please note, some routes may also see some minor improvements for textures, reducing the blurriness that appears, but this was not the focus of this update, and will be our goal moving forward.
In the advanced settings, you will now find three new advanced settings, that allow you to toggle if custom liveries, custom formations or substitutions appear, providing flexibility to your experience, and additional ways to manage memory.
This patch was just the first half of a two-part memory update, with the next part aimed at addressing a concern we've seen where players aren't seeing some of their layered content on particular routes. This should provide access to all of your owned layers, an issue which is directly related to memory.
As we look to the future, now that stability has been addressed, our focus will prioritise tackling blurry texture and visual quality. Thank you for your continued patience while our team works hard to ensure the best experience possible.
If you experience any issues following the update, please alert our team.
