Ongoing Pascal latency problems - Hotfix doesn't work for everyone. - Page 15

Everyone with Windows 8/8.1/10, please use LatencyMon instead.
The deprecated Latency Checker will always incorrectly report 1000μs.

Can a note be added to the OP about Latency Checker's incompatibility with Win 8+?

much better results on Latency Monitor. Latency checker was pegged at 1000us, latency mon stays in the green zone, although the variance is pretty big, from 20us,through 40,100,200 up to max 500us spikes.

The deprecated Latency Checker will always incorrectly report 1000μs.
It will report 500us when you switch the OS into a higher resolution such as playing a video in a video player, there are "secret" functions in the OS DLLs that are used by some to get this higher precision timer. There are also paid apps that call these not so easy to find functions to get the higher resolution.

Sure Latency Monitor is far better and has a list of processes and so on which is quite important.
Latency checker will still detect the highest garbage though, it's more simple and easier to understand for newbies.

Correct, but the output is still false information.

It's almost certainly a driver or configuration issue, not a hardware issue.

Getting rid of a card that there is no real alternative to, when the same cards don't universally produce these problems would be premature.

Having measurable problems is one thing, having ones that most end-users are going to notice is another.

Many people with DPC latency spikes ten fold higher than I will tolerate will never suspect there is a problem and, even if shown a nearly latency free system, may not be able to notice any difference.

I have tested my self on three different systems now with same high dpc with the 1080 as soon as i place the 980 ti no problem

1080



980 ti it does spike up to 200 but this is normal as you can see the 1080 is terrible



the only thing that resolves the issue for me with the 1080 is going high performance with the power settings but one should not have to do this if the 900's where fine
post #148 of 1679
this is what I've been getting on my 1080 today (win 8.1)

post #149 of 1679
I assume DPC latency has to do with low-priority (aka DPC instead of high-priority IRQL) interrupt handling? That's almost certainly a driver issue.
post #150 of 1679
I read the article about interrupts and deferring instructions and priority level and get how they are related. My questions is if I have an external sound card like the SBZ in my computer is this still an issue or are these issues with sound processing handled by the sound card only?
