Topic: D.P.C. Latency Testing
I found a link to this, more advanced, DriverPack Chipset Latency tester called "LatencyMon". Vista is required at a minimum.
It is free for home usage, however; commercial users are required to license it. This is also true with Thesycon's D.P.C. Latency Checker (compatible w. XP though).
"LatencyMon checks if a system running Windows is suitable for processing real-time audio and other tasks. LatencyMon analyzes the possible causes of buffer underruns by measuring kernel timer latencies and reporting D.P.C. and ISR excecution times as well as hard pagefaults. It will provide a comprehensible report and find the kernel modules and processes responsible for causing audio latencies which result in drop outs. It also provides the functionality of an ISR monitor, D.P.C. monitor and a hard pagefault monitor"

I would to suggest that this type of software could be used to help determine driver update suitability. Consider that this is not simply to determine causes of lag or skipping in Audio only. It can be applied to Mass Storage, Video, Network (incl. WiFi - especially Atheros), USB et al. Perhaps differences would be more apparent on single-core systems. In my thinking; whatever 'rocks' on a single-core system should 'kick-ass' (soarry Donkey) on a multi-core system!
PS: I have no connection (personal, professional, nor financial) to either company.
