Windows 7: Please explain nVidia nvvsvc.exe and nvxdsync.exe processes.

The Windows update for 7 is a little different, but also installs nVida control panel.

I'm not sure you get the question. I never said I wanted to disable them or keep them enabled. I was saying there are 3 processes, and I need to decide whether I want them running or not. In order to decide, I need to know what each of them does. If they don't do anything I consider important, then they can be disabled. If they do something I consider important then I can leave them running. This has nothing to do with anything being slow. If I don't have a clear answer on what each of them does, the how is it possible for me to decide whether or not I want them to run?

There are 3. I know at least one of the nvvsvc.exe is for graphics effects and capabilities. I sill have no clear information of whether or not the other one is also for that. And no clear explanation of what nvxdsync.exe does.

If anybody can explain it, great. Please do so because I can't find any explanations anywhere. If you can't explain it, then that's fine also. I got alot of extremely vague answers on my question about HDCP compatibility until finally getting a few real answers, and putting together a legitimate real explanation that isn't totally vague.

Sometimes there just is no getting a satisfactory answer. The big corporations don't go around telling us geeks every little thing about what their files do and how or why. You'd have to start reverse-engineering them to get to the bottom of things.
But in agreement with previous posters - just leave them be. You probably need these services to be running for a trouble-free experience with the driver and/or control panel.

Doing a bit of research on my laptop, I see that nvvsvc.exe identifies itself as "nVidia Driver Helper Service." This is pretty vague, sure. Some kind of link between the control panel and low-level access to the video driver? Memory management? Not sure. I do remember I tried disabling this service a long time ago and the control panel promptly started behaving oddly.
I have two instances of nvvsvc.exe running - and we can hardly even talk about "running" here as they're both taking up a combined 5MB of RAM, practically nothing, AND still show a total CPU time of 00:00:00 since last time I booted my system. Which was a week or two ago. Hardly a waste of resources, I'd say

As for nvxdsync.exe, it calls itself "User Experience Driver Component" - seems to indicate it has something to do with how the control panel presents itself and the configurable settings to you. Maybe support for more than one display or SLI configurations. Again I can only guess, and again this service has used all of 4 seconds total CPU time on my system. Again, negligible.

I'm pretty anal about streamlining my setups and disabling unneeded stuff too - but when 1. I can't find out whether something really IS unneeded or not and 2. I start seeing strange stuff once I do disable it, then the answer is pretty clear for me: Just leave it be. That's the best answer I can give you.

Relax.

Relax.
It's not really an answer. I'm not asking whether or not I should leave it or disable it. I need to know what they are so I can make an actual decision on whether to leave it or disable it. You're speculations about these processes are no further than mine were since I started this thread. I haven't seen anybody in this thread post any clear explanation other than vague speculations which really does't resolve anything.

The question that is the purpose of this thread is still not answered. If anybody can provide an actual answer. Perhaps, run tests if possible to find out, it would be a great help to alot of people looking for real solid information about this topic.

I did say I can't really give you the answer you seek (see my first paragraph). Really sorry, but you might as well ask about the purpose of most .dll files in the \Windows\system32 folder. I understand your frustration, believe me - you *could*, if you really want to go that far, try your own research via process monitoring tools, utilities to map out the structures in the .exe files, heck even open them in Wordpad (messy lol) and see if you find plain text that gives you any clues. There are ways

As I said up-front; disable the service(s) and see if you notice.

Or ask Nvidia--I suspect if there was anyone here who could tell you want you want, they'd have weighed-in already.

DIY if your standards are so high or bother ManuelG. You won't get a different answer - incorporated in recent drivers to help in the latency issues of cards such as the 460 & 560 and power state regulating.

In terms of HDCD capability, I do not think this has anything to do with the driver, but rather the HW itself.

Most modern Graphics cards are compliant.
The next part is that your display itself is.


Yes, some of the answers do seem a bit vaugue, as no one seems to for 100% sure.
However, from what I can see the sync exe has impact on:
The Control panel itself, power state regulation, and latency issues.

The Control Panel portion itself is a big deal simply because without it, you loose a lot of control of your graphics card.

If you are quite familiar with how your GPu & its Control Panel works, try as suggested and disbale 1 service at a time to see what effects they have.
You will find it does somewhat cripple the driver and its capabilities.

To me this a very important part. But, whether thats important or not to you is obviously your call.

I also think these services work together to a extent.(Speculation here)
Sort of like how some Win7 services do.
You may not have any need for one of them, but by disabling it can possibly hurt another aspect or service you do need/want.

No the HDCP situation was where I asked a question about it, and nobody could give an answer while everybody claimed that my question was answered. The somebody extremely unprofessional closed the thread claiming that the question was answered even though it wasn't. Eventually, I was able to compile enough information no thanks to anybody in that thread complaining about me not being satisfied with vague nonsensical answers. And with that information, I was able to start a brand new thread explaining exactly how HDCP worked.

Same thing with Fatigue in Allods. Not a single person could give an explanation on how Fatigue worked. Then many of them complained about me not being satisfied with their answers. It turns out alot of the explanations were false, and not a single person actually knew how Fatigue worked while giving all kinds of explanations that were supposedly accurate. It wasn't until extensive testing that I figured out the entire Fatigue system, and provided a detailed guide on exactly how it worked despite all the false information about it.


My speculation from the beginning is that one of the nvvsvc.exe processes might be controlling the nvxdsync.exe process. Which is why there is no way to disable it in order to see what the effect would be.

I said in post #2 that nvvsvc.exe was responsible for NvXDSync.exe--a simple matter of looking at Process Explorer.

I wonder why you are making such a big deal out of this. The NVIDIA services are not at all hidden. I have two shown:

NVIDIA Display Driver Service (nvvsvc.exe & NvXDSync.exe)
NVIDIA Stereoscopic 3D Driver Service (nmSCPAPISvr.exe, not running that I can see)

Do you not see these on your PC? You can't stop, then disable?

I'm not making a big deal. I'm asking a simple question. What is so difficult about sticking to the question and topic?

There are 2 nvvsvc.exe. Despite saying that it handles nvxdsync.exe process, it doesn't say if that is all it handles. Or if it does anything else. Or if one of them does, and the other one does something else. I cannot disable the nvxdsync.exe process. It comes right back.

I'll try to disable all of them, and see if I can get any answers.
