Question: Fast buffer? #5

Hi! I noticed that at VGA (640x480) the pushImage is very slow, taking almost under a second of time to write the image to the hdmi output from top to bottom.

I need to write a full vga buffer to the display at once (renders only the whole frame, not pixel by pixel), preferrably at 60 FPS. For my graphics, I need to render to a buffer in RAM that I can write to the display, then it should output the whole image at once and not sequentially (instead of for example drawing every line one by one, resulting in way more lag and latency than buffering the lines in an array and displaying the whole image)

Is that possible?
