Zero chance of that happening here.HDCP is copy-protection over HDMI, it's to prevent copying 4K/2K video streams using a capture device.
Disable HDCP? whats that?
I cant see an amd gpu under £100 at my usual supplier, cheapest is £180. Eff that just for basic duties.
Dont really want to chance fleebay for used HD 6450s, they may crap out at any moment.
I did the same settings and way of uninstall/install as you with my install. Only thing changed was all processors not close ones and audio driver. Glad my way worked for you. It may not work for everyone though.When creating the NVcleanstaller installer you can select the option to disable HDCP, It's essentially some nonsense copyright protection. Wikipedia describes it as such: "The system is meant to stop HDCP-encrypted content from being played on unauthorized devices or devices which have been modified to copy HDCP content."
It will not be the be all end all of reducing DPC latency but every little bit helps I guess.
As for the GFX cards, I'm kind of lucky that I have a business that deals with audiovisual media so I can get some tax breaks when purchasing new hardware, otherwise I wouldn't have bothered either. Especially since for just watching videos online or basic PC use lower end cards are perfectly fine. For videogames you really have to love the Triple A games (I don't) for these expensive cards to make sense since even a GTX 980 or 1080 (Ti) will still run an insane amount of games with no problems.
I would sell mine to you for a hundred bucks when I upgrade to a 3060 or 70. Just might suck with shipping depends on where your from. Either way it would probably be cheaper then what you have looked at.Cant find a silent low end gpu card, cheapest at both mu usuals is £190
3) Netflix and all other such apps work with it disabled.The latest series of posts sound promising, but I think before we close up shop there should be some follow-up testing to confirm and isolate the solution.
1) It could be that driver version 516.94 or some other version right before it simply fixed the DPC issue in the driver.
2) It could be that NVCleaninstall was always the solution, because at whatever driver version Nvidia started adding all of the telemetry and other stuff, these things are causing DPC spikes, and not installing them is what's fixing the issue. If this is the case then we could also test this by installing the driver version right before they added the telemetry stuff and see if the DPC issue goes away.
3) I don't think this particular issue is MSI related, I had zero difference with that. It can of course help some people if they have IRQ conflicts.
4) Disabling HDCP I think is going to come with consequences. Try watching Netflix for example on your computer with it disabled, I would wager it won't work.
I'll try switching over to this driver version and/or using the NVCleaninstall and report back too.
I wouldnt even pay £100 for new. Shipping and import duty would rocket the full cost to 150+. I would rather chance a used hd 6450 for £30(inc delivery).I would sell mine to you for a hundred bucks
Just might suck with shipping depends on where your from
Ok, I'm back.
I've been going through the exact same methods I've already used before, again.
and...
I think I might have fixed the problem, at least for now.
What I've done is extremely basic and maybe I just got lucky, because I've already done this before and it didn't work:
Create an installer using NVcleanstall:
- V516.94 (Thanks Necrosaro)
- Nothing but the drivers.
- MSI on (obviously). Priority: high. Policy: All close processors.
- Disable HDCP.
Safemode reboot. Pull out Cat Cable.
Run Display Driver Uninstaller (DDU) in safe mode.
Remove absolutely everything + Restart.
Run the custom Nvcleanstall Nvidia installer.
Turn off PC. Plug in Cat cable.
Turn on. Run Latencymon passive. No issues.
Run Latencymon while having a game open on one monitor, a YouTube Video on the second monitor and furiously start refreshing tabs.
(Refreshing tabs seemed to cause a lot of popping when a video was playing previously)
Result:
The Nvidia drivers don't even show up as a major contributor anymore.
Now maybe I've spoken too soon (knock on wood) but even if the problem is gone I might still purchase an AMD card in the future, I'm curious to see if it's really better out of the box, as already discussed, DPC should be used when benchmarking by tech sites and if AMD is simply "cleaner" than Nvidia that should matter. What good is a slightly faster GPU when it creates other (devastating) problems from the get-go?
Check if HPET is disabled in device manager and not biosDamn, I followed exactly all those steps and still get nvlddmkm.sys DPC latency in the thousands
It was worse for me for some reason disabling it in bios then in device manager. Didn't do any ticks just device manager.Disabled hpet in bios, set that power setting in the control panel to max, 500+.
HPET is usually hidden in a bios, some say disabling hpet in device manager dont work.
Platform tick blah blah blah, some say yes some say no.
There is no definitive do this do that. Now where did i put that blue pill,,,,
My BIOS doesn't have any setting for disabling HPET, it's always enabled.Check if HPET is disabled in device manager and not bios
Worth a try, can you show a pic of your resultsMy BIOS doesn't have any setting for disabling HPET, it's always enabled.
Disabling or allowing it in the device manager makes zero difference for me.
Was a good idea though :c
What are you wanting pictures of?Worth a try, can you show a pic of your results
Also your computer specs just got the heck of it.
Is this on a vanilla windows or a modified NTLITE windows?
Was reinstall as in format and squeaky clean?What are you wanting pictures of?
With and without HPET disabled in the device manager?
Both give DPC in the thousands from nvlddmkm.sys.
No where near as bad as what I was getting from ACPI.sys though...

I resolved ACPI.sys by disallowing HDD's from powering down in the Windows Power Options.
Like magic, ACPI.sys stopped causing any issues whatsoever.
Not an ideal solution imo, but I couldn't figure out any alternatives.
My specs are:
Gigabyte Z390 Aorus Pro Wifi
Intel 9900KF @ 5ghz
Corsair Vengeance DDR4 RAM 32GB 3000mhz
Nvidia GeForce RTX 3080
Various SSD's, and one HDD.
I've never used NTLITE.
I recently reinstalled Win11 and have since noticed the issue with nvlddmkm.sys.
Unsure if the issue was present before reinstall, but the issue I have/had with ACPI.sys absolutely wasn't present before the fresh reinstall.
Yep yep, sure was, formatted every SSD and did a pure clean install of windows 11.Was reinstall as in format and squeaky clean?
