Strange image stuttering while having 60+ FPS?

It's happened on every free AV I've tried. Not at the same time, but once it happens on the AV I happen to be using at that moment and it doesn't get fixed for a week or so, I find it's time to move on.

The free AVs it's happened to me on: Comodo, AVG, Avast, Avira, Panda Cloud. If you go into any of their support forums, there'll be a thread buried in the forums that mentions this issue. It eventually does get fixed once enough people actually bother to update more than just the definition, but til then I stay away.

*edit*

oh, and the reason for maxing out at 25-50% of CPU capacity tend to be due to being locked to a single-core process. My 1558 (8 logical threads) would get locked at persistent 12% CPU usage b/c of Comodo, my e1505 on 50% at 50%, a friend's i5 at 25% on Panda.

 

I dunno. I've used Avast for a couple years now, put MSE on a couple machines just to see if it was fixed and never had the issue with Avast. MSE it always happens, so not going to bother with it any more.

 

Considering I deal with a dozen(s) of laptops or desktops any given week. I've got plenty of opportunity to run into the CPU hog bug, why haven't I but three times?
Like I mentioned before the 3 times it's happened, the updating of windows resolved the issue. Even then those 3 times, the computers were quite old.

A netbook with a 1.6 ghz processor would get jabbed with overload by simply running youtube at 480p... What can you possibly expect out of a single core (sometimes multi threaded) processor, 5400rpm hdd?
Most netbooks are meant for word processing/web browsing, not running your full featured operating system with a set of security tools on the side, 5 web browsers, and your media player. At least not unless you pay a hefty sum for a better processor, and more ram ($400~, which puts it at a notebook price).

Can you replicate the results, also are you running on a fully updated windows?

 

You got it wrong! My CPU is not a 1.6 single-core! It's a quad core with HT giving me 8 threads! With TB to 2.8GHz!
I am now using ESET SS4 trial, and it is MUCH better than Norton in terms of weight. But they both let go through 16 adwares and 2 Trojans ( scanned with MalwareBytes ) I think I will stick to ESET.

 

There's no need for hostility phistacio, we're only trying to help. Given that your problem could have many causes, it's hard to track down something like that. Without actually being there in front of your computer it's hard to diagnose.

 

You have a quad core i7 at 1.6Ghz, nuff said. How many "threads" you have is meaningless. Having 8 threads doesn't make it like an 8 core processor.

 

What the hell are you talking about? Please re read your own thread as I think you are lost.

I was speaking with someone else. Do whatever the hell you'd like, I am not going to sit here and educate you on malware/adware/viruses/rootkits etc.
You obviously know better, why are you asking for help?

 

The thing hyperthreading does, it executes threads when others are idle. For instance, if you have one core that's sitting there doing nothing but you have a thread in the queue, it will execute it while it has nothing else to do. As soon as the core resumes the original thread, it stops executing the hyperthreaded "thread". I believe I remember reading once that hyperthreading on average only gives a 7 - 10% performance boost overall.
The OS sees them as real cores because in the way the operating system delegates work loads. By seeing them as real processors it can process additional threads as cores become available.

 

That is mostly correct, but there is no distinction between a "real" thread and a "hyperthreaded" thread. I have seen ranges from as low as a 5% decrease in performance to 25% increase in performance, but these results are atypical. Usually games don't see much benefit while programs that are very linear in the work they do see the most benefit.

 

Yes I know, but I was making that distinction to explain to the OP how hyperthreading works.

 

I wasn't being hostile or rude! I meant "You got it wrong" in the friendly way! I hate being rude, so sorry of you got it wrong

EDIT :

Could you please tell me, what are threads? Are those thingies that executes files?

 

Sorry! When I said "you got it wrong", it was in a friendly way! Not in a rude way! I hate being mean, so my apologies if you took it as an offense

 

Anyways, back on topic :

I've tried with MSE, ESET and Norton, and still I have stuttering and FPS Skipping. The only way of not having them is with NOT having the AV, something that is pretty risky. Will changing the HDD to a 10000/7200RPM one solve the issue? What about an SSD?

 

At this point there's little we can do to help you solve the issue. There's many tests that need to be ran and results that need to be checked.

For now here's a few things I do if I notice stuttering in games (typically because I am checking how high of settings I can play them at):
1. Lower Anti Aliasing in game settings. Try disabling AA. For reasons of lack of hardware (ROP's/SP's etc) and other things laptop graphics cards have problems handling high Anti Aliasing settings.
2. Remove Vertical Sync, goes by some other names like triple or double buffering. Vertical sync is quite taxing on mobile gpu's because of the mobile gpu's having less hardware available to use then their desktop counterparts (Stream processors/etc).

FYI there's no 10,000 RPM sata 2.5" hard drives that I know of.

Also keep in mind Metro 2033 is a very CPU intensive game. It's called the new crysis for a reason.
Try those recommendations out first. Let us know whats going on. If it stutters still, try lowering the settings overall.

 

1- In NfS World there is no option to turn off AA, but when I play L4D2 I can play all max with 8xAA and 16xAF without stuttering or FPS Skipping.
2- Didn't thought that VSync could provoke problems... Will try it
3- Dont know if it's compatible, but still Western Digital intros 2.5-inch 10,000RPM VelociRaptor HDD -- Engadget
4- When I play Metro 2033, it NEVER reaches 100% CPU usage ( no core ever reached 100% usage, max was on about 60-80 )

 

1. Okay. Don't mix games, it's not a good idea unless they're running off the same engine. I don't have NFS world installed anymore, however I could of sworn I saw AA, but I suppose.
2. Yes it can, turning it on uses more resources.
3. Interesting. Probably not worth it from a 7200 rpm laptop hard drive.
4. Okay, interesting..

 

If I change HDD to a faster one, will there be some kind of gain?
And when VSync is on, why does it uses more resources? What does it uses from the GPU to VSynchronise?

 

Edit:
Uhm only with loading of games, loading of operating systems and programs. I don't think it will help with the stuttering your witnessing..

Because the images produced by the GPU, it can often go past 60 fps. Monitors using DVI, or VGA or HDMI you have 60 hz limit (60 fps). This creates tearing, so it matches the monitors refresh rate to fps (60 typically) to prevent tearing..

Basically if your FPS is lower then 60 fps, don't use it as it could have a negative impact on your FPS. If it's considerably higher (100 fps+).

I am afraid I've forgotten which hardware part it uses from the GPU to do the syncing between the monitor's refresh rate and the gpu's output fps.

 

I saw a thread a while ago on here about core parking causing the stuttering on the i7 720q's. It was regarding the cores parking, then waking, causing a delay in response. Soon after I bought my lappy, I added a ssd, and still had the stutter. I have the 720q in my asus and after disabling the core parking, it went away. It only went away after disabling the parking. I will try to find the thread and link it here for you so you can at least read about it.

 

Here is one of the threads. I would suggest you read it, then make your own decision. There are several ideas, one involves deleting the registry key, the other involves changing the values. It revolves around the Win7 power saving. I used the one changing the values for minimum and max. If you really need the max battery savings it would not be a good solution, as it will affect to a degree the amount of time you can run on a battery charge, But I don't use mine on battery much, so I opted for losing the stutter. Hope this helps, and as I beleive is stated in the thread several times, if you do decide to try it, back up your registry first.

Just as an FYI, although the Velociraptor is a technically a 2.5" drive, it's power and cooling requirements limit it to use in desktops or blade servers. It's a 2.5" drive that's usually in a 3.5" casing with included heatsink. There is a version of it without the 3.5" casing, but it still requires more power than a normal 2.5" drive, as well as being 15 mm tall instead of the more usual 9.5 mm or 12.5 mm.

So, essentially, no, the Velociraptor is usually not compatible with a notebook.

 

Thanks for the info, but

Those different keys you're telling don't have the same number? How do I know if it's that key, and not another one? Should I change to 0 all keys that have "ValueMax" with a 64?

EDIT:

Ive just changed the value on that reg key, and now all my CPU cores are NOT parked! Thanks! And now I get in "Max Frequenc" always around 110%!

EDIT 2 :

I have tried, and it fixed! No more stuttering!
@ Crimsoned
Disabling/enabling VSync didn't have amy difference, the final fix was disabling the CPU Parking

 

Huh? What "tering"? Please write like a normal person...

 

Does he mean 'stuttering'?

 

How the hell can it stutter when the CPU is on 100%? xD It shouldn't since more is better. Oh and those 110% were meant when playing L4D2, will see how goes in NFS

 

If the CPU is maxed out (ie. at 100%) then that is exactly when the 'stuttering' will show up.

Just a guess.

 

In metro I have stutterin with CPU at 40% ( metro only uses that amount lol )

 

Just FYI tearing is an issue with vertical and horizontal refresh rates not stuttering.

Hard drive is a possibility.
I suppose a way to test it is to run the preferred game, and stay very near an area from where you start. This will prevent further areas from being loaded thus hard drive would be out of the equation. Let me know if you get stuttering there as well.

 

Tearing isn't caused by lack of data. It's caused by too much. Tearing is caused by display data overwhelming the refresh rate of the display. This may help:
