I just want to double check if this is still the case? since main page still shows the cap of FPS much lower.

Main page still shows up to 15000fps. The graphics/charts for frame rates they do show are for more widely used 4K and 2K ratios, so you’ll have to create a custom lower resolution setting to achieve the 15000fps.

The maximum framerate is limited by the vertical resolution. Each horizontal line is always read in full, so horizontal resolution only affects storage space.
15,000fps is still possible - albeit at a severely limited vertical resolution. I plan to put together a comprehensive interactive chart to derive maxFPS from Y-res soon, but I can share some insights in the meantime:
The sensor reads in blocks of 32px tall, so the minimum vertical resolution is 32px at which you can get up to 20,920fps. Next up is 64px, for a 15,873fps rate. While the horizontal res can still be up to 4608px, the vertical res limitation means those extreme rates are only for experiments and/or scientific purposes, but it’s nice that they are available.

Yea for me these higher framerates are extremely useful as I do a lot of experiments.
I would not mind to have less colors for more FPS.
Here’s a quickly drafted chart to illustrate the relation between vertical resolution and max FPS for the 10bit mode:
20920fps is the absolute maximum achievable rate with the camera, at 32px tall in 10bit color mode.

Thank you, you mentioned that this is in 10bit mode.
Would there be any possibility to have 8bit mode with higher FPS or more resolution?
