X-Plane 12.3.0 Release Candidate Adds Vulkan Ray Tracing and Multi-Core Aircraft Systems
By David Marlson · · 2 min read
Laminar Research's 12.3.0 RC brings Vulkan ray tracing for enhanced lighting and a new multi-core architecture for aircraft systems, promising improved performance and realism.
Laminar Research has pushed X-Plane 12.3.0 to release candidate status, and it's a significant leap forward. The headline feature is full Vulkan ray tracing support, which brings real-time shadows, reflections, and global illumination to the sim. In our testing, the visual uplift is dramatic, especially in dawn and dusk lighting, where the new soft shadows and ambient occlusion add a level of depth previously unseen in X-Plane.
More importantly for systems nerds, the update introduces a multi-core simulation architecture that offloads aircraft systems processing to separate CPU threads. This allows complex add-ons like the ToLiss A340-600 or FlightFactor 767 to run with less impact on frame rates, as their intricate electrical, hydraulic, and pneumatic models can now operate in parallel. Laminar claims a 20-30% performance improvement in CPU-bound scenarios.
Early adopters on the forums have praised the stability of the RC, with only minor visual glitches reported on AMD GPUs. The new weather system, refined in this version, also sees improvements in cloud rendering and precipitation effects. It's a welcome maturation of the sim, and we're eager to see how third-party developers leverage the new architecture.
Laminar has not announced an official release date, but the RC status suggests a public rollout within weeks. Given the scale of changes, we recommend backing up your current installation before switching to the RC channel.
