Week 45/2023
November 6th-12th, 2023

Simulator

• Krzys292 - the second stage of optimization, which involves division of every scenery into chunks. Sceneries will no longer be loaded all at once, and static objects like plants will be split into "chunks" dynamically loaded within the camera's render distance. This has shortened scenery loading times, increased gameplay smoothness, and reduced the frequency of the black loading screen when loading another scenery. As a side effect of the applied system, there are a few seconds of stuttering when the dispatcher teleports to distant signal boxes. The system is not active in the editor - there, the scenery is loaded all at once.

Models

• Marcin_S - showcase of progress on the cabin of the ET22 locomotive in the "Graty od Marcina_S" thread

Week 47/2023
November 20th-26th, 2023

Introduction
Yet another week was dedicated to optimizing various simulator mechanisms. Internal tests show significant reduction in scenery loading and unloading times, a significant decrease in freezes during these operations, and a general increase in framerate. Thanks to the generosity of GitLab, we managed to obtain a commercial license for our most important tool free of charge. This license unlocks several important features for us, facilitating work organization (e.g. ticket dependencies). As part of Black Friday, taking advantage of the ongoing shopping frenzy, we also made several purchases, mainly servers, but we also bought two models.

Simulator

• During in-team tests, specific data on the chunk system were collected. According to them, using this system, depending on the hardware, sceneries, and other settings, loading times can be 30-70% shorter, gameplay smoothness can increase by 20-40%, and RAM usage can be about 30% lower.
• During the ongoing work, processes that affect performance during scenery loading were identified. It turned out that many elements were loaded very inefficiently (in addition, some resource-intensive processes were unnecessarily invoked multiple times), resulting in significant performance drops and long loading times. Thanks to the introduced changes, which mainly concerned the method of loading tracks and switches, as well as adjusting the limits on the number of loaded objects per frame, it was possible to significantly speed up and streamline the loading process. In the coming days, tests will measure how much this will improve scene loading.
