I want to load a remote image that will be centered on the screen. Using HTTPRequest I successfully loaded the image… but it’s toooo slow@!!@#

My project settings are using Stretch mode: 2D which means the image needs to be a big size because of scaling. If I try to load a 1472x849 image… it takes about 5 secs to display the image.

Is there a way to load an image faster or maybe make it ignore the scaling of the window. In this way I can load an image with smaller size

func _on_request_completed(result: int, response_code: int, headers: PoolStringArray, body: PoolByteArray) -> void:
	
	var image = Image.new()
	var image_error = image.load_png_from_buffer(body) if fileExtension == "png" else image.load_jpg_from_buffer(body)
	
	if image_error != OK:
		print("An error occurred while trying to display the image.")

	var texture = ImageTexture.new()
	texture.create_from_image(image)

have you considered loading the image on a background thread to avoid slowing the main thread?

Yup - if you don’t need it instantly and can plan 5 seconds ahead - use thread.

Otherwise I would check what actually takes this 5 seconds. If it’s download itself, there is not much you can do, except improving network infrastructure :frowning:
