Cruiser platform uses Mapsforge engine.
Cruiser GL platform uses VTM OpenGL engine.
Different technologies, VTM is more modern with OpenGL acceleration, map rotation / tilt, etc.
But the fundamental reason for the problem here is not the engine, but the map data at those areas.
They should have categories per importance / size and not all nature data thrown together with same tags… then how map makers are supposed to filter them?
By the way would expect that GPU on such modern phones to be able to handle anything.
But then many phones with >FHD resolution, fall back to FHD for games, here is the answer.
