Stuttering, is it similar to XP's infinite loop?

[Kruno]

I have been reading and reading, 1 group of people have stuttering and another don't.

I have managed to reach the conclusion by reading threads that end up more and more like this:

http://www.driverheaven.net/showthre...&threadid=8407

Remember the infinite looop bug wasn't only in XP it was there since 95. In XP they gave it the name "infinite loop" as your system would go into an infinite loop.

Now what this has to do with Radeon's?
Well it seems people who had stuttering have fixed it by doing a thing or multiple things (like in the link to the thread above). Infinite loop bug was also fixed by changing/playing with an option or fixing faulty hardware or whatnot etc...

I have been reading threads from multiple sites (Rage3d, Nvnews, Driverheaven, Beyond3d etc...). So I have come to the conclusion these stuttering problems are not caused by Ati's drivers directly as many people like myself do not have stuttering anywhere.
Multiplayer games and single player games alike run perfect.

I just install the drivers and that's it. All games run fine.

I have played (including as many mods (engine mods included) as I can get my hands on):
JK2
WC3
Quake 1,2,3
Vega Strike
RTCW
HOMM4
Doom 3 Alpha
SS:SE
AvP 2
Clive Barker's Undying
Snes9x (not a game but an emulator, played FF6 rom along with 7th saga)
EPSXE (FF5 and FF4, both sprite game but I though I would include them)
Morrowind
4x4 Evo
SOF2
Commanche 4
Delta Force 3 LW
StarCraft (why I bothered to include this is a mystery )
Half-Life
Unreal Tournament
A few more game which I can't remember...

All these games ran perfect. Not 1 problem with stuttering or any glitches.

I played all these games in multiplayer as well. (the ones that were capable of it, Undying is not capable of multiplayer).

My system:
P4 1.8Ghz (from 1.5GHz)
Intel i845 mobo
Radeon 9700 Pro (Catalyst 3.0 drivers (unmodified) with DirectX 9)
768mb RAM
SBLive
Altec Lansing Speakers and Sub
Logitech Optical Mouseman Wheel
Logitech Wingman Gamepad
Lifeview Flyvideo II TV Tuner
Samsung SV4002H hard disk
Samsung DVD-ROM SD-616
Windows XP Home

The infinite loop is caused by data being sent from card to system memory or vice-versa over the PCI bus (AGP is PCI remember) and not being acknowledged. Each transaction must be replied to or it will be assumed a failure. The Infinte loop is when the PC hangs waiting for this responce, and a number of other similar bus failures.

Stuttering is like the infinite loop in that data is sent to the card, then the communication just seems to stop almost as if a chip somewhere locks up waiting on something. It then times out and resets itself and stuff starts moving again. Most probably the North Bridge controller if you ask me.

I see what you are saying and it is a possibility.

Ati cards are not the blame for the stuttering as their is more to it than the video card.
Certain Ati drivers tend to fix stuttering up with people with systems that do stutter. The exact cause of the problem eludes me.

I have not suffered from 1 stutter. Trying to help other people with stuttering is difficult.

I have experienced the problem in one game so far - Lucasarts battle for Naboo. I have a P4 2.53 and a Radeon 8500 with dual boot Win98 and XP. I installed it on XP and I had the problem. When I installed it on Win98, the game worked perfectly.

That can be for various reasons. Try using memory usage for system cache and not programs if you have not done so already.
There are so many things you can do to tweak it, there is bound to be a way to make XP run better.
