Hi, I am running DPC latency checker and have 4 milliseconds, lol, I just moved my mouse -usb mouse-, and it went off the charts past 16 milliseconds. moving my ps2 mouse does not increase the height of spikes, but now as i type i see that typing also increases this spike to near the top.
.. I am wondering if it is safe to disable all of the devices in device manager.
by the way, i tested my mouse on another computer running windows 7 with default driver from 2006, and it worked fine, but when i ran it on my computer with the default driver from 2006, it did not work well, creating massive lag, and causes video and audio to drop data and stutter. So my mouse+driver works, but my computer is not functioning correctly it seems.
