It's a long time since I've used or worked on fbtft, but maybe this pages can give some insight: https://github.com/notro/fbtft/wiki/FPS https://github.com/notro/fbtft/wiki/Performance

greyscale
The ILI9341 supports RGB565, RGB666 and a reduce 8-bit color mode for power saving. I couldn't find anything about greyscale in the datasheet.

Hello, I've got a 16:9 video playing back on a 320 x 240 pitft(ili9341) using the fbdev library. Its getting around 19fps which is to be expected.
I was wondering does fbtft support partial updating of the screen? Because its a 16:9 video, theres black bars which are adding unecessary bytes to the transfer.
Also, does fbtft support greyscale format with the ili9341 to possibly triple the frame rate?
Cheers Russell
