Ongoing Pascal latency problems - Hotfix doesn't work for everyone. - Page 37

post #361 of 1679
The rare spike to ~500 microseconds isn't going to be perceptible by much of anyone in much of anything, and I wouldn't worry about peak execution times in that range unless they are very frequent.

There is essentially zero difference in DPC/ISR latency or execution times between idle and maximum load on most of my systems.

Reviewers usually have higher than optimal test setups with nothing but the essentials, glorified PCs that resembles more to ASICs machines, or anabolic consoles with performance centric tools.

This latency problem will generate issues with anyone running a small amount of programs in the background, even if it's just steam and origin if they don't strip down their PCs out of all extra Windows/non essential Windows processes.

You're better off waiting for Nvidia to release their fix as that should reduce your DPC latency even more than disabling your NIC, which admittedly suffers from a lot of DPC lag as well.

I don't know what are the bests NICs regarding DPC latency, I might look into it later! Changing your NIC and having fixed Nvidia's drivers will make up for the best possible gaming/PC usage experience.

What he said. Is there a recommendation on PCI network cards? Particularly one which has a driver that plays nice in terms of DPC latency?
post #364 of 1679
You guys can't possibly now be considering a dedicated NIC because Intel drivers reached 70 microseconds.

Everyone ever has done incredibly well without them, but now a latency checker suddenly makes you want to spend money for absolutely no measurable benefit.

Besides, i don't see how an extra layer of both hardware AND software would ameliorate the problem. CPU usage with modern onboard NIC's is negligible.

^ agreed


I wouldnt give a crap about latency numbers unless it starts affecting your performance or usage

lol tell me about that wink.gif I can get sucked into things like that pretty easily tongue.gif
when I was picking up a PSU I got so into comparing tiny mv differences in ripple supression that I ended up spending 3x what I initially planned, including a power bar that cost me as much as a decent PSU that would probably be fine for my needs at that time biggrin.gif

If one optimize one's system for DPC latency one can offset the high Nvidia DPC latency easily, making it a non issue, while improving system performance. (Which translates into more stable gameplay in the end)

Ignore ChevChelios, he is known to not care/Downplay/Smokescreen any issue that affects Nvidia., regardless of importance or impact.

Driver Tab on LatencyMon, this isn't available on Latency Checker, you can even order the processes from higher to lower DPC lag.

Who said anything about 70 microseconds? When I check my system for DPC latency my integrated NIC is a repeat offender and its only trounced by Nvidia's driver. I never liked the integrated NIC to begin with that Alienware used on this Foxconn motherboard. I also don't get why you say an extra layer considering I would clearly disable the integrated NIC while using a PCI NIC. I couldn't care less about CPU usage. Its strictly a NIC performance and driver performance issue I would like to improve upon.

dont be salty towards me just because you get stutter wink.gif

most people dont have any audio/gameplay issues with 1070/1080, its unfortunate that your system does


thus either sell the Pascal or wait the driver
