Now We Are 3

With X-Plane 860, we now mark the X-Plane executable as being capable of using 3 GB of virtual memory on Windows. This means that if your copy of Windows can support large address spaces and you have a powerful enough PC, you can now use more add-ons. (Mac and Linux have always gone to 3 GB by default.)

You can read more about setting Windows up to handle large address spaces here. Please don't try this if you don't know what you're doing, and please don't contact our tech support if you destroy your copy of Windows -- we can't support the whole OS.

Please note that this change does not improve the hardware capabilities of your computer - it only enables X-Plane and Windows to take full advantage of what you have. You will not see a performance boost because of this.
