I understand that it is possible to be accurate to the millisecond (or 10 msec at the worst) in determing the latency of a keypress following a screen display (using directx?)..
is this possible using a java applet? I have heard of a toolkit called SWT that allows hooking a directx interface to java apps under windows.
second question pertains to display time.. this depends on the refresh rate..
say if the display was at 120 hz, one could display a slide for around 10 msec (close to 9 msec) accurately (using directx in windows?)
would such a thing be possible using applet/app under windows?
