| RW Enhancer 2 feature a complete, easy to use and optional Vulkan renderer for Train Simulator based on the DXVK open-source project (modified with some tweaks to better run with Train Simulator). Once enabled in RW Enhancer 2 settings, this will temporarily replace the DirectX 9 renderer of Train Simulator by the modern Vulkan renderer. This new Vulkan renderer can have many benefits for Train Simulator especially when playing on routes with a lot of complex geometry, 3D vegetation or complex tracks layouts. The Vulkan renderer is also greatly reducing micro-freezes and framerate micro-hiccups, | RW Enhancer 2 feature a complete, easy to use and optional Vulkan renderer for Train Simulator based on the DXVK open-source project (modified with some tweaks to better run with Train Simulator).

| + | =====Planned Improvements===== | ||
| + | |||
| + | In it's current state the Vulkan renderer can provide a more stable framerate and some performances improvements depending on the routes that are being driven (3D complexity, tracks layout...). But in some cases the framerate could be lower compared to the default DX9 renderer of Train Simulator. That's why some improvements for the Vulkan renderer are planned in the future in order to improve it's performance and efficiency. | ||
