1107 fps on the V2 IMX219 camera. I wonder how fast or how large of a frame it could do on a Pi4 or odroid (article mentions the 640x64 frame is limited by memory bandwidth).
In tools directory you can use *_s tools to get double FOV vertically while keeping the framerate. So you can get 640x128_s@665fps/640x256_s@667fps for v1/v2 camera.
There real limit for v2 camera is 1007fps, with can be achieved with 640x75 or 640x150_s tools. You can reduce vertical resolution below 75, but you will not get more than 1007fps (if you find out how to raise that limit, please shout! Deal for raspiraw high framerate capturing basically is "halve vertical resolution and get double framerate").
