Steps to Reproduce

Create a large Tilemap (100x200), this is relatively easy to do with the infinite tilemap feature in the Tiled plugin. See https://github.com/BreadBox64/RoscoTheRoswellRacerTwo

It seems that the PointerEventToObjectDispatcher.processPointerToObject is the main source, this could be improved likely with some spatial data structures and refactoring.

Expected Result

Pointer dispatch should be fast < 1-2ms at most

Actual Result

Huge performance hitch 200ms+ during dispatch code

Environment

• browsers and versions: Chrome
• operating system: NA
• Excalibur versions: 0.30.3 (and latest main)

Current Workaround

Remove pointer events from Tilemap

const tilemap: TileMap = ...;
tilemap.pointer.useColliderShape = false;
tilemap.pointer.userGraphicsBounds = false;

// or

tilemap.removeComponent(PointerComponent);
