Did someone has an benchmark from the lib between oldone on mega how fast is it?
I don't use the UTFT library, but I have a sainsmart TFT shield with a mega using an SSD1289. I'm interested to see how it compares to the Due implementation.
An easy, but important test is clearing the screen. To be able to present games flicker free, the clear operation needs to be one of the fastest.
I have achieved a rate of 51fps for a clear screen operation on a mega 2560, this is in a loop clearing to a random colour.
It will be interesting to see how well the Due performs in this basic operation.
