During a panel at FlightSimExpo, X-Plane 12 developer Laminar Research revealed upcoming features and changes coming in the next few updates.
We learn that the next update, 12.4.4, dubbed “SDK Update,” will be mostly a developer-facing one. It’s slated for Q3 2026.
It’ll include the new panel graphics API, which will help developers create advanced avionics based directly on Vulkan with a high-performance, low-overhead rendering system.
This includes smooth TrueType font rendering and anti-aliased vector graphics, while allowing direct access to systems maps, including Synthetic Vision and Weather Radar.
Here’s what you can expect from the new API.
- New Vulkan-based avionics framework
- Modern architecture with minimal overhead
- High-performance rendering pipeline
- Easy-to-use developer workflow
- Smooth TrueType font rendering
- Anti-aliased vector graphics
- Access to Maps, Synthetic Vision, and Weather Radar
- Compatible with both C++ and Lua (xLUA 2.0)
- ImGui support
- CEF support
- Developer previews available now
Further features of the update (some of which are more user-facing) include:
- Weather Radar Improvements
- CPDLC Support
- New SDK Tools
- Additional Scenery Assets
- Farnborough Airport – An enhanced X-Plane Gateway airport with custom assets, this airport is a key UK connection for business activities.
The next major update will be 12.5.0, dubbed the “Flight Model Update,” and slated for Q4 2026.
It will include the following.
- Rotor Blade Tracking
- Improved Skid Interactions
- Expanded Helicopter Procedures
- New Manifold Pressure Simulation
- Improved Turbine Temperature Modeling
- Enhanced Ground Physics
- Enhanced Wake Turbulence
- Enhanced Swirling Prop Stream Effects
- Improved Hydraulic Systems
- JFK International Airport – An enhanced X-Plane Gateway airport with custom assets, this airport is an iconic US gateway, that is bound to please both regional and international pilots!
Perhaps more exciting is the preview of the Tile Engine, which will form the base of what Laminar defines as “next-generation scenery.”
It’s designed to replace DSF scenery, which is basically 2004 technology, although backward compatibility will be preserved.
Here’s what you can expect from the engine, alongside a few examples of what it enables in terms of visuals.
- New X-Plane scenery foundation
- Tile-based and layer-based architecture
- Support for Levels of Detail (LOD)
- GPU-friendly rendering
- Streaming-ready infrastructure
- Expanded raster data support
- Flexible patching and editing workflows
- Fine-grained terrain modification
- Improved scalability
- Foundation for future scenery technologies
The developer is targeting late 2026 to have the Tile Engine online in X-Plane 12.
It’s worth mentioning that the Tile Engine and DSF compatibility represent only the first two steps of what X-Plane defines as “next-generation scenery.” Two further steps that will come later include the support of “next-gen 3D file formats” followed by the actual launch of the next-gen scenery.
We’ll have to wait and see what that means.
