I found that the game still trashing the HDD, even having free RAM to use, and that event cause shuttering.

If the game is not limited in the use of RAM and detects the available resources, and this objects are previously loaded in RAM, the HDD trashing shutters will disappears.

Maybe is the search of this resources in the HDD what is causing this CPU hold back, or just is another source of shuttering different.

Well, I looked hard for that. By doing sequential track playback runs - where the track is already in RAM after the first playback - you figure your getting around the disk access issue.

It actually looks to me (if I had to be forced to guess) like a broken thread. i.e - one of the many processes that runs threaded, just had an error and stops. Then the process has to go and find something to "do".

In short after several hundred runs this week, I saw no evidence of storage access issues.

S!

So there two sources of shuttering.

Im talking about the first load in RAM, for example flying in "free fly mode" when you are approaching to a city the game shutters searching in the HDD some thing, a house or something, when it is already in RAM there no shutter flying the same zone.

But there free RAM, why is not this loaded already ?

About the strange issue that there better performance with AA in x8 than in x4.

That is a ATI issue, they have better performance in x8 than x4, even if it is not working properly, dont know why

Understand. I included the first load (1st run to the left) and as you'd expect - it always benched differently. The Average would usually be 3 fps higher. Normally, when your track testing - you throw out the initial run and take the subsequent track playback benchmarks. The first one is always different, and your trying to isolate CPU and GPU - while leaving out the I/O variability between systems.

Also, there's a part of TBD track (later portion of track) in which the camera zooms into a RAF Flak Gunner. In almost every (if not all) of the intial passes after restarting CoD - the animation would be missing ammunition load in the AA gun. All other passes - the ammo showed up and as the gun fired the ammo load decreased.

I hate that Flak Gunner by the way. He has a bug. His vertical position is too low - so that the AA Guns seat - passes through is neck - instead of his butt.

I'll be glad when they fix that and I won't have to look at it anymore.
