Laminar Research have now released a huge upgrade to their flight simulator with X-Plane 11.50, which brings in lots of rendering changes and advancements.
A massive release, since they completely rewrote their rendering engine to provide Vulkan (on Windows and Linux systems) and Metal (on Mac). This should provide X-Plane 11 players with smoother frame rates, with far less stuttering and better performance overall. For the Linux version you need at least NVIDIA 440.26 and for AMD they're supporting the 'official AMD GPU drivers' along with amdvlk but they didn't state any particular version.
What else does it bring in? Looking over what they've done it adds:
- 498 new airports
- 1,742 airports had either no scenery or 2D-only scenery in 11.40, but have 3-D scenery in 11.50
- 2,427 airports gained some new scenery
- Tons of bug fixes
That's a huge amount that went into it, all in addition to a much more modern and performant rendering engine.
It may take a while for things to settle down, especially when it comes to all the addons since a lot of them need updating for the new systems. According to the release announcement, it's a staggered release. With the standalone you can manually check for an update, whereas on Steam it's still in a Beta branch but it seems they will push that to the main install for everyone tomorrow.
