Also nev could put this multi display power saver part right into Lav Cuvid utilizing NVAPI additionally and implementing a switch (always keep P8 state on/off)
For most this would be useless though as you need they dynamic of their system else you always gonna endup with to slow results and Nvidia has to find this best dynamic on the driver level which is hard as they have to take a lot of different scenarios into account it never will be perfect in (performance/power/latency) for everything that's for sure (Web,Games,Video,Folding)
The last time Nvidia Engineers tried to lower the latency most cards couldn't hold that stress and errored out, especially Gamers where not happy with that
