Whenever you change the image of a Quad using .ChangeImageUrl() or .ImageUrl, the game is creating a HEAD request to the specified image. I think this is to recognize any changes of the image on server side.
The problem: If you are constantly changing the images (like in Tetris), you create A LOT of these HEAD requests. I am speaking here of around 20 requests per second. This is too much in my eyes.
Would like to have an official comment from Nadeo on this issue
