If you find something affecting latency you could update the driver or you could uninstall or disable if the application is unnecessary. I did this with Nvidia Display driver, got a latency improvement and was able to reduce UltraSize from 160 to 120.
I'd be very careful about uninstalling though unless I was sure what I was doing.
Yes I've been listening to V5.1 and it is very impressive. I'm using UltraStream all the time now and the atmosphere it creates is superb. If I walked into a room where Xtream was playing the sound would be excellent, detailed,musical etc but switch to UltraStream and it's goosebump territory. I'd like to explore the lower reaches of UltraSize and I'm envious on those who can go down to 20 but I'll wait until the network card controversy is resolved and the brighter sparks on this forum get the home built PC sorted.
Do take a chance to call round anytime suits you.

my i3 build gets down to 28us on ultrastream its been playing faultless with jplay 5.1 but gets an odd click or pop on 26us,
ill bring it with me when i call down, hopefully we will get 28us on the ciunas and see what its like.

Well, I just pulled the trigger on the i7 3770 processor - best I could find was 264.89 on german ebay for new but tray packed so without the cooler etc. Seems the best deal I could find.
So add this to the costs from before and the total build is coming in around 484 or so:
I already have the case, SSD, power supply for the pico, W8. So for some others that would need to be factored in. Cost excludes little bits and pieces like the umbilical cord from the linear power block to the PC etc.
and the page file errors, i didn't find a solution as yet
how did you get on with yours john?
On my netbook, I found the culprit that causes the spike was Windows Defender - anti-virus software - I disabled it through Apps & now have 0 Pagefaults.
I was getting a spike like you & this was stopping Jplay Ultrastream in single PC mode (even at 200 Ultrasize setting) - it was annoying - about to test it now with Jplay.

the i3 is playing hi res nonstop perfect in single mode at 30us in ultrastream i suppose that the main thing
im turning off windows defender atm, ill recheck latency now
fingers crossed
wouldn't mind i read the post on jplay about antivirus before (stupid me)

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Got another pagefault spike & tracked it down to Windows Search Indexer - turned this off too.
Seems I have low page faults now.
Decided to go with this WTG config to boot my NUC.
Into the usual network issues of not connecting - can't pink between the netbook & NUC using ethernet cable.
Disable WiFi card on both NUC & netbook.
Set NUC ethernet IPV4 IP to fixed addr 192.168.1.30, subnet mask 255.255.255.0.; default gateway 192.168.1.1
Set Netbook IPV4 IP to fixed addr 192.168.1.31, subnet mask 255.255.255.0.; default gateway 192.168.1.1
I'm slightly hampered by not having a screen or keyboard attached to NUC so working blind but I have booted it with WTG before, attached to HDMI TV & it boots fine into Win8

can u not use a tv and steal a keyboard from somewhere, it will slow u down a lot id imagine
i think when your Ethernet adapters are different on the nuc and laptop you lose your settings when you swap the WTG over as there will be network adapter 1, 2, 3 depending how many pcs you've plugged the WTG into
