Latency, IRQ, lockups, sluggish interface
Been researching this and at the bottom of Daniel Robbins' PCI Latency article (http://www-128.ibm.com/developerworks/library/l-hw2.html) he mentions a program called Powertweak (http://powertweak.sourceforge.net/).
I have recently used Powerstrip on my XP games box to tweak PCI latency values so have some small understanding of these and was wondering if anyone has tried this out?
If not I am going to have a stab at setting up my MythDora box with it and will report back. (I've been meaning to test out the new smoke detector in the room anyway!)
