Im having weird problems now, Before i had none an game ran just fine but now i just get this werid stuttering/lag/slow in game when fighting or when im even talking to someone, My drivers are all uptodate along with my game. Have not a clue at all why its doing this. Specs below.VVVV

OS Name:  Microsoft Windows 7 Professional
Processor: Intel® Pentium® D CPU 3.20GHz, 3211 Mhz, 2 Core(s), 2 Logical Processor(s)

You could probably glaze pottery with the heat being thrown off by that old Pentium D... I suggest monitoring temperatures. May not be the issue... but the symptoms are classic.

XD, Its all good no heat off that baby, Along with that i bene watching it letting it sit in game doing circles for about a hour an still kicking out the cool. So its not tempature problem ; /.

Then you might want to lower your graphics settings and see if that provides more stability.

Had already done that ; /., For some odd reason it just does it when it wants an i unistalled/reinstalled to see an i still get the problem, im lost & confused at this point. might try to delet some programs thats might bring some problems.

Also i use other programs in help of running games, along with nice to use for example - Gameranger.
Which is rare because when i use that baby, Games run even better, But not this time XD.

I also have an nvidia 9800 GT.  I also have an AMD Phenom II x2 CPU with the other 2 cores unlocked, and using WIndows 7 x64 Ultimate.  You might could try using the version 191.07 drivers. That's what  I use and DOA seems to run fine with those drivers with 4x anti-aliasing.  From my experience using the latest drivers can sometimes cause stuttering and crashes in games depending on what type of graphics card and OS you're using.

i see, i will have to try that when i get the time, Will get back an let you guys know, Also i been useing Gamebooster (Bought) an its been working well with that with a bit of stuttering but solve the problem whole be nice.

I'm trying to hunt down the solution to this problem on my end as well; I'm posting this in multiple locations as it seems the discussion is a bit fragmented.

The unusual thing about this problem is that it initially emerged when I was nearly done playing Dragon Age: Origins, I believe following a patch. Before then, the game ran smoothly on my machine. Since then, Origins, Awakening, and sadly Dragon Age II have all been affected.

Symptoms are: smooth running for ~30 seconds after start, then heavy stuttering, typically when a conversation starts. Frame rate plummets and sound comes with heavy "crackling" sounds.

My platform is a Dell Precision 6400M, which I use for algorithm development & simulation.
Intel Core2 Quad CPU, Q9100 @ 2.26GHz
8.00GB RAM
Vista x64
"Windows Experience Index": 5.9


For context, I am an experienced developer; I've been treating this as a debugging problem. I've updated all drivers, run with a wide variety of settings (graphics quality is irrelevant; sound enabled/disabled is irrelevant; disabled antivirus, disabled steam overlay, disabled all services I could).

What I've found so far:

1. Setting core affinity to 1 core appears to slightly improve the problem
2. Setting "minimum processor state" to 5% *significantly* improves the problem
3. Running the game on all 4 cores leads to a CPU usage of ~76%, or a full three cores.
4. Kernel times appear to spike when this lag happens, but is hard to quantify.

Running the game on 1 core with 100% minimum processor state leads to 25% (one full core) usage.
Running the game on 1 core with 5% minimum processor state leads to a CPU usage of ~21-24%.

Without these settings, particularly #2, accessing the character stats menu is extremely laggy, and within ~1 minute of starting the game, the sound crackling problems start.

The reduced CPU settings seem to suppress the periodic sound-crackling/frame-rate disaster, at the occasional cost of some occasional lag when the game engine has to page in new data (e.g., as I run around an area).

Theories:

1. There are some idling threads that do not have appropriate "Sleep" statements, and as a result they are consuming as much CPU as they can. It would explain why I can run the game just fine on 1 core - you guys have some threads that are doing nothing.

2. These idling threads may potentially be polling the Windows API for something? This could help explain the kernel times; potentially, these threads could be causing competition for common a common resource.

There appears to be a connection with the sound (i.e. dialog being spooled up?), regardless of whether or not sound is enabled; there also is a connection with the user interface (specifically the character stats menu). I observed this in Dragon Age: Origins & Awakening as well.

I'm going to run CodeAnalyst and see if it gets me any further information on what's going on. I'd also love to have a developer investigate this threading question, because I'm honestly curious at this point.

Get back an let me know what happens. Also try useing a program called Game booster in which helps with performance of many games an soo forth, If we do seems to solve the problem an dont ill make a sticky allowing my use of my Copyright of Gamebooster for tohers to use for the team being.

Problem solved, for myself anyway. Holy cow, do I feel like a noob.

Undoubtedly this will not solve the problem for everybody, but for me the problem was overheating which was causing the system to throttle CPU down (I only caught it because I was running Perfmon on the same screen, and I noticed that when the problems happened, this coincided with a drop to 70% max CPU frequency. Now everything appears to run smooth as butter, once again.

To any other laptop users experiencing the stuttering/lag issues I described: CLEAN YOUR FANS OUT! :-). I initially saw somebody else recommend this solution, but I didn't think it would explain the behavior I was observing. It does, in fact, explain it very nicely.

(Laptop users: hold a paper clip to the fan to prevent the blade from getting damaged by spinning too quickly, and blow compressed air into the vent. Pick out the large clods of dust that will pop up).

Nos, try running in a windowed mode and keep an eye on the % Maximum Frequency in perfmon.exe - see if it drops below 100% when the stuttering occurs. Good luck...!
