i could do a LatencyMon export for my ltsc 1809 but its all klingon to me and i disable software and bios hardware that is unacceptable to 99.99999999% of users so it would be pointless but would be nice to know my improvements if someone could translate it into "thicky speak".
I think I might be able to help:
1) Run LatencyMon as admin
2) Go to the "Stats" tab
3) Click the green arrow to start on the top left, let it run for about 5 minutes at least
4) In the "Stats" page, in the header "Measure Interrupt To User Process Latencies" you'll see some measurements:
"Highest measured interrupt to process latency"
"Average measured interrupt to process latency"
Below that header is "Reported ISRs" and "Reported DPCs" and that will show what driver is responsible for the spikes, in the "Highest ISR/DPC routine execution time".
Basically all this stuff is just measuring latency--how long it's taking for various OS/Hardware/Drivers to do their calculations. Higher latency is always bad, for everyone. If it's too high you get stutters in games, audio dropouts/static, etcetera.
Anything under 100 microseconds is really good. If you have things spiking up above 500, then those are likely issues that need fixing in your computer (if the spikes are fairly frequent). If it's just a single spike and never appears again in the next few minutes than it was likely just the OS doing something in the background that caused an issue for a moment.
If you do find a problem, such as really high spikes then you can look around at the other tabs to see what the culprit is. The "Drivers" tab for example, can be sorted by "Highest execution" and you can usually see the problem files right there at the top.
I'm sure someone else can break all this down a lot better than me, but this gets what you need.
