That's great. With latecymon you can see the issues with Nvidia has on the system... some times the dpc is too high make system unstable. @JarredWaltonGPU can you make a review of this new driver?

It's already possible to fix the DPC latency, and has been possible for a few years...

I haven't got the original link (my apologies to the originator)

1.Openup Regedit and go to
\HKEY_LOCAL_ MACHINE\SYSTEM\CurrentControlSet\Control\Video\*****\0000\
The *'s will be random numbers . There will be a few of them, pick the "0000" folder with the most keys in it

2.Create the 4 PowerMizer keys (these will all be DWORD)
PerflevelSrc
PowerMizerEnable
PowerMizerLevel
PowerMizerLevelAC

3.Change the values (double click on them) to
PerfleveISrc 3322
PowerMizerEnable 0
PowerMizerLevel 1
PowerMizerLeveIAC 1

The fix won't be in drivers till R540, standard QA for KMD changes is 3-6 months.

Are they talking about this De Guzman?

Man what a double standard between Nvidia and AMD. AMD still gets **** for their old buggy drivers back in the day yet no one considers a years old and still active and debilitating gaming bug from Nvidia to be anything of merit…

You'd have a point if it affected games at all.

It did, thus it does…don’t get me wrong I’ve bought Nvidia from the 4400 ultra up to the 1080, so I’m not just an AMD fanboy talking

This keys code has no effect on RTX 40 Series, It is not work. Don't talk nonsense. It's not fixed the DPC latency issues.

chill. all I know is before the fix latencymon would only show my system was struggling, after I did the fix in regedit it's showing my system is suitable

Your test is not suitable. The test time is too short and you do not have any DAC implementation application.

NVIDIA officials have listed known issues and said they will be fixed in the future.

 

[mta1124]

You are not on the NVIDIA development team either. Advertising that this issue has been fixed is ridiculous.

dude i'm not even the one suggested it

Sorry. I don't mean you

@pdixon0 is not on the NVIDIA development team either. Advertising that this issue has been fixed is ridiculous.
