addedWe've added a physics calculation load reduction and an auto-generated mission feature.
changedReduced Physics Calculation Load Previously, when approaching a curve with 30 or more freight cars, the increased physics calculation processing became a bottleneck, preventing the GPU from being fully utilized and resulting in a significant drop in FPS. We discovered that this was primarily due to the calculation of contact between the wheel flange and the rail, and we optimized the flange shape, significantly reducing the load. The graph below shows the result of accepting a 30-car mission and departing from Cham City. The orange area at the top shows the physics calculation processing (left: before improvements, right: after improvements).
changedAuto-generated Mission Feature and Simultaneous Mission Acceptance Previously, only pre-prepared missions were available, but we've now added a function to automatically generate missions. Specifically, you can now accept previous missions separately using the "Mission Alpha" button and new automatic missions using the "Mission Beta" button, allowing you to complete multiple missions simultaneously. Additionally, the respective mission buttons will display red while an active mission is being accepted.
removedRegarding temporary disabling of the trial version Due to the significant discrepancy between the early access version and the trial version, we have temporarily disabled the trial version.
