Extremely high frame rates needed (>400 fps)

I’m working in R&D on some custom experimental hardware, and I need a graphics card that can output pre-rendered video at the highest rate possible (over 400 frames per second at 8-bit 1080p at least).

This presentation http://on-demand.gputechconf.com/gtc/2015/presentation/S5613-Abhijit-Patait.pdf suggests that the Maxwell architecture can encode video at over 450 frames per second,
but is there any similar information available regarding decoding and playback speeds?

Searching the internet for relevant information about “maximum fps possible” has only led me to a deluge of irrelevant information. I’m really hoping someone here can point me in the right direction.

Yes, I have the same question! How to get many hundreds of fps or even khz rate if possible.

This is not for gaming, but displaying patterns to an external device.

Also, if the display pattern is 1 bit depth or low bit depth, can the fps increase?
