Although we continuously will try to optimize things there is precious little to gain. Please note that you need to let this test run for a few minutes before you get stable results. As long as your base FPS is not too low that should not be a problem. It should not be a problem though as our FBW system is robust enough to handle a second of low fps. We offset that partly by having other modules only take resources when needed. This puts a constant high load on the system. In contrast to many other add-ons there are many things we have to calculate in a frame by frame base (because of the FBW and the fact we need to intercept the throttle commands). Note that almost no laptop is able to handle this in hardware!
If you got a modern graphics card, make sure the software ECAM rendering is off. To activate the options remove the red // character The options are explained in the comments in that file.
It is now possible to edit some functions via the AB_ND_GDI.ini (to be found in MyDocuments\Aerosoft\Airbus.
