The aircraft model is rather atypical than the average aircraft models featured in Flightgear. Contains millions of vertices and few textures, the reasons for this choice were the need to be able to reduce, almost dramatically (see this [[Howto:Methods to replace the dial gauge bit mapped texture with vectorial objects]]), the GPU load and allow the use of such a detailed aircraft even on poorly equipped machines. Currently the aircraft has also been used on 2008-2012 PCs with 8 GB of RAM and 2 GB of GPU, which I would say surprising and which demonstrates the lightness of Flightgear compared to other simulators. Obviously I recommend the use of more performing machines, at least of the generation starting from 2016 (4-6 cores) that have video cards of at least 4GB. In these conditions, as for other aircraft in the traditional Flightgear hangar, it is possible to have all the features present in the latest versions of the simulator active. | The aircraft model is rather atypical than the average aircraft models featured in Flightgear.

I have often noticed that many speed problems with this aircraft, but also with many other Flightgear aircraft, are resolved by activating multithreading with the option: | |||
'''<multithreading-mode>AutomaticSelection</multithreading-mode>''' | |||
Inserted in the configuration file: ''../fgdata/defaults.xml'' Which is, still incredibly, disabled by the standard installation! Activating this option can lead to a performance increase of 30-50%. However, as reported here: [[Howto talk:Activate multi core and multi GPU support]] hopefully it will soon become standard. | |||
