Laminar Research has released version 11.51r1 of their popular X-Plane flight simulator. This update comes about a month and a half after the release of the first v11.51 beta, which you can read about here.

X-Plane v11.51r1 is a release candidate version of the upcoming full version of 11.51. Rather than releasing large updates all at once, Laminar Research improves its X-Plane platform by releasing incremental beta versions of each update, followed by release candidates, which are the culmination of the beta releases to be tested before the release of the final version. v11.51 of X-Plane has thus far seen three beta releases, all with their own additions, improvements and fixes. This is the first release candidate for X-Plane v11.51.

According to Laminar, the release includes over 2,200 added or improved airports, as well as a list of known issues and bug fixes. Some of the notable fixes include improvements to the default FMS, various fixed ILS approaches, Vulkan/Metal optimizations, and 3rd party peripheral optimizations among many other fixes. You can read the full list of fixes for v11.51r1 below, as well as check out the release notes page on the official X-Plane 11 website here.

X-Plane 11.50 Now Final, Released

Fin Vulk
After many, many, MANY beta releases, Laminar Research has finally made X-Plane 11.50 final and official. The months of testing helped the team ensure that the move from OpenGL to Vulkan/Metal was as stable as possible. This is a huge change to the way in which X-Plane 11 runs and as such meant that it took a long time to

Laminar Research Releases Beta 6 for X-Plane 11.50

X Plane 11 2

Following on from a very quick and unfortunately unsuccessful Beta 5, Laminar Research has released Beta 6 for X-Plane 11.50.

Laminar Research has released Beta 6 for X-Plane 11.50 which corrects a lot of the instability issues that have been plaguing the releases thus far. Ben Supnik has reported in a post over on the Laminar Research blog that the team has received an unprecedented amount of bug reports, both automatic and manual, since the release of 11.50b1. although the volume has been intense, the amount of information the team has received has been invaluable.


After seeing the amount of data received from the reports from users, the team have put a plan of action in place to gain ground and get closer to a solid release. Firstly, the team want to work on fixing the fatal crashes and bugs that prevent X-Plane from loading and moving forward, they will then look at optimisation in terms of VRAM, and finally look at mopping up any further performance issues.

Laminar Research Update Status on X-Plane 11 Vulkan/Metal, Cloud / Weather Addons to Work with Vulkan

F 4 2020 02 12 4.28.17 PM 1 1600×900
When we last spoke to Laminar Research about the anticipated Vulkan/Metal update, Ben told us that some weather add-ons such as SkyMaxx and xEnviro would not work with Vulkan due to limitations. This has since been found possible thanks to a happy accident. In a full blog post written by Ben at Laminar Research, he goes into explaining how since
