sorry for my english
i get strange stuttering issue with my pc: 
core 2 quad q9400 2.6 ghz
amd 6950 1gb
4 gb ram ddr2

in some singleplayer levels like the first mission on earth i get small occasional fps drops while looking around.
after few seconds they are gone and my framerate returns to normal 60 fps. It is almost like the game loads level around me. Rly annoying.
same thing with multiplayer maps in Bad Company 2 - game stutters for few seconds, than goes back to normal.
But Skyrim, BF3 and many others works fine.
is this normal? somebody else get this? 
i even post a screenshot

I had this issue too. I think it's Origin's fault. I disabled its in-game feature, and since then no longer I've had stuttering.

already tried
didnt work

Try to disable Hyper-Threading in ur BIOS. Also make sure you use at least Windows 7, preferable the 64 Bit Version and enforce the use of the high-precision timer (has to be enabled in ur BIOS also in teh right bit mode and enforced in the OS). Also disable any Hardware components your not using (say if you have 12 USB ports u rareley use and some obscure onboard components or such disable those (as much as possible through the BIOS and the rest through the windows hardware manager).

Good indicator for problems often is the System Information utility (msinfo32.exe), check what hardware recources are used and possibly shared to isolate issues.

ok, thank you for replay
will try
im using Windows 7 64 Bit

[Delusion83]

A good indicator for problems often is the System Information utility (msinfo32.exe), check what hardware recources are used and possibly shared to isolate issues. Technically it nowadays shouldn't be a problem in modern Operating Systems but the underlying hardware often lacks behind with these standards, so while technically recource sharing shouldn't cause issues it often does when timer issues and power management meet IRQ/ INT sharing in hardware at high load or usage spikes.

Also a source of stuttering can be caused by CPU power management (also often can be disabled through the BIOS and on the OS side within windows power management). You could give the high performance power mode a try.

Oh and another one are actually all kinds of dynamically adjusted "features" like "dynamic overclock", "turbo boost" and such, software assumes certain conditions/ timings, dynamic variations cause issues there so disable these in the BIOS as well if your's should have any.

btw, the game really loads content/ level around you ("streaming") but on your hardware it shouldn't make a noticeable impact. Make sure you use the latest drivers of all ur hardware.

[Wild_Division]

unfortenatly couldn't find Hyper-Threading and high-precision timer settings
still thank you for all the help

[Delusion83]

You give up that easily? Did you access your motherboards BIOS?

For HPET see --> link

[Delusion83]

Also did you look up your System Information utility (msinfo32.exe) results? IF you wanna solve it u gotta put more effort into this.

[Wild_Division]

yes i accessed BIOS
no Hyper-Threading and high-precision timer settings
my motherboard is asus p5q turbo
if i am correct ASUS has removed the HPET 32/64 bit {ON} options from there motherboards...
but it seems ACPI 2.0 Support is the same thing so i will try to find it

upd: it is turned on

Ok, that's progress but you still have to enforce it's use within windows! (see link!)

Ok to make it easier,
here is how to enable HPET:

open cmd.exe as an administrator (elevated)
and enter this:

bcdedit /set useplatformclock true

(press return)

now reboot

---------------

If you ever want to go back to default timers (no reason to really but anyway) admin cmd:

bcdedit /deletevalue useplatformclock


for everyone else reading this, only do the above when you are 100% positive your board supports HPET and has it enabled within it's BIOS!


Also check this and make sure it's all at 100% and the PCI Express power saving settings are disabled (later you can switch between power modes - "high performance" for gaming and more energy
efficient "balanced" for everything else as needed) .

Oh and another potential source of issues is related to harddisk access through SATA/PATA/ AHCI -controllers (on newer motherboards you should enable "AHCI" and "native SATA" via ur BIOS which usually looks like this or that or similar to this, ignore the settings on these screenshots, they are just examples for you to know where to look).

Make sure you have the most recent drivers for your motherboard (in the OP's case Intels chipset drivers) and furthermore Intel RST and third party SATA/PATA/ AHCI -controller drivers installed (there are newer beta versions available but for the purpose of this thread and ppl seeking help for similar issues you can take these as they are the most recent official and stable drivers and in most cases already vastly newer than what ppl have currently installed).

On most mainboards you have at least 2 of those, eg. like one onboard intel SATA/ AHCI controller and another onboard third party controller (say "jmicron") which also takes advantage of their own drivers and special bugfixes (most ppl forget those).

If you'd like additional help, take pictures of your BIOS pages (quality doesn't has to be great just has to show clearly what settings are available and set) and upload them, also post screenshots of what msinfo32.exe displays. Example of the mess you can find there at times.

For everyone else reading, you're welcome to do so too, just make sure to mention your complete system specs (mainboard model, RAM, OS and so on) and I will help you get the best out of your hardware without overclocking or anything out of the ordinary.

wow
thank you very much for all the help
ill post here after trying everything abovementioned

[Wild_Division]

also on my old gtx 260 stuttering was present but not so noticeable
and i did clean driver installation with driver sweeper and so on

could it be cpu bottleneck with 6950? 
exept for stuttering issue, general perfomance is a lot better then with old card

Your CPU is still quite capable, I only have a core 2 duo at 2,6 GhZ so you got 2 more cores than me, even tho mabye the Unreal 3 Engine might not use them efficiently enough, you should be ok (even moreso for future games/ engines which should put ur 4 cores to better use) as it runs very well on my setup already (nvidia card tho, albeit being a much slower and only DX10 hardware card; the GTS250).

I believe the Unreal Engine is running better on Nvidia Hardware usually, they seem to work closer together with Epic (Unreal 3 Engine) which is also marketed ("the way it's meant to be played") so it might just happen they don't optimize some things on ATI hardware, totally by accident of course ^^

Also they have many, many workarounds in their engine which are dragged on forever even tho the core of teh issue is already fixed so those stayed around on top of things which if you ask me doesn't help but Epic seems too eager to work on their Version 4 Engine instead of fixing their version 3 flaws.

Also in general even on Nvidia Hardware the Unreal Engine 3 (also used in ME3) has quite the terrible streaming/ lod/ cache system so even on the endorsed hardware micro stutters and all kinds of lag are well known, but still ur system is capable of handling things better compared to mine, which means there is room to optimize things (as suggested in all of the above).

ME3 is not that taxing really, I did not encounter such issues aside from slight slowdowns in some inengine cutscenes (when my hardware get's close to it's limitations, which doesn't happen often in ME3 and in those cases seems more to be related to cache handling/ streaming by the engine).

When u tried all of the above get back with some feedback and if it still isn't better I have a few more ideas.

okey, so updating chipset drivers, enabling HPET and AHCI didnt remove stuttering but improved general perfomance of my system So it was still very helpful.
ill will make in near future photos of my BIOS

btw i had same issue with Fallout: New vegas (even worse)
downloaded mod that fixes it and no more stuttering
so it is not completely hardware problem?

[Delusion83]

There are many possible causes for stutter/ performance issues, your hardware itself is fine. Which ATI driver are u running and are u manually forcing any settings in it's drivers menu?

On top of all these possible issues of how the OS handles ur hardware or how a game puts it to use the Unreal 3 Engine has certain issues, still ur hardware is capable enough to mask these so they should not be very noticeable if at all. I recommend to do as mentioned above so I can see if there are any issues left and when that is off the list there are a few ini/cfg settings you could try.
