came across this in searching because i also have eyestrain problem with win10, only tested laptops so many other factors can come into play like gpus and screens.
i see data loss with this audit mode is a concern but maybe if more people have a reduction of the strain using it this could be answer for this particular issue.
could then results be sent to microsoft or other researchers to figure out what audit mode does versus a normal mode.
thanks for reading! :-)
