OANS Performance Mode

Description

For me personally the OANS is a bit performance heavy. So on big hubs I can not use it properly.
It would be great to lower the resolution of the map which is shown in the ND. As I've also noticed e.g. the inibuildsA350 quality is a bit lower then the A380 I assume there is room for optimization.

I've had a look at this file: fbw-common/src/systems/instruments/src/OANC/Oanc.tsx
export const OANC_RENDER_WIDTH = 768; export const OANC_RENDER_HEIGHT = 768;
export const OANC_RENDER_WIDTH = 512; // Reduced from 768 export const OANC_RENDER_HEIGHT = 512; // Reduced from 768
Make it more like a factor which is maybe settable in the EFB

const RESOLUTION_SCALE = 0.75; // Add this constant at the top const width = (dataBbox[2] - dataBbox[0]) * RESOLUTION_SCALE; const height = (dataBbox[3] - dataBbox[1]) * RESOLUTION_SCALE;

Also change the draw rate maybe accordingly:
const FEATURE_DRAW_PER_FRAME =50

For example:

What I am not familiar is is antialiasing. Maybe disable this also for OANS to save performance.

FYI, FEATURE_DRAW_PER_FRAME will not impact your FPS after loading the airport map. It dictates how many features are drawn to the canvas image while the map is loading (the PLEASE WAIT screen).

I see. Thank you for the information. I am not really familiar with this topic. Maybe all my suggestions are wrong, I don't know.

I think an "easy" optimisation to use less VRAM would be to reduce the resolution of some of the layers that are only shown on low zoom levels
