Motives:
1- because Microsoft has grouped several IRQs W8 kernel to save energy and latency has increased considerably ....
(This mean that Microsoft poop on musicians and producers really)
Test that we do.
Well according to my own ASIO tests:
W7 - 5-10ms average lat
W8 - 24-50ms average
measured with various programs (CEntrance Latency Checker, resplendence latencymon, Cubase panel, M-audio, vst custom C + + dev, etc ...).
According to the DPC Latency Checker is 500ms + W8, but I think it is a failure of the program.
I guess it depends on the drivers, your hardware, etc ... but talking to various people have more latency W8 ... (Besides being disgusting OS user for all the changes introduced by M $, cause problems with new drivers, etc. ..).
coment of i will challenge to kotipelto.... you choice .....
