The sharp decline in FPS

[tomasz-c]

In the latest version noticed a very large drop in FPS. On my card (Intel Core i5 M 450) is a drop from 15 to 5 FPS, making it impossible to have a game.

By git bisect found that the cause is commit: 00213ee

Is it possible to optimize it?
Many players do not have the latest graphics cards, and the plane was one of the few that had a low requirements.

That version introduces the canvas-based navigation display, which finally works. Since canvas is a general tool in FlightGear, please, direct requests for its optimization to FlightGear.

The ND canvas in this version produces a lot of errors and an FPS drop by ~25 (80%)
The errors produced are:
storms update requested! (timer issue when closing the dialog?)

(many per second!)
Are you sure this isn't an aircraft-specific problem, @jan-hudec as I've seen other aircraft with canvas ND working fine....

Turn off WXRADAR?

How to? ;)

Down to the pedestal, behind the thrust levers on the far left is the weather radar control panel.
