Frame stutters - what are the causes?

[machoo]

Game runs well on a whole and I have just about every detail on high with no problem apart from this. From my observations it happens alot when you are shooting apart aircraft and they are taking damage. In the background I assume the game is calculating what is getting hit and it has to freeze to catch back up on occasion? That or it's a texture loading problem but usually the stutters are worst at the beginning of a large battle with bullets ect flying about and things getting hit.

What are your observations?

edit : This also happens with small single plane battles too , so it's not a memory issue at fault ( or shouldn't be if coded properly ) A good of fire burst with multiple hits on an aircraft will lead to a stutter atleast .

An old age bug mate.. its been like that since the last 2 patches I believe..

Hopefully it will get fixed in the next patch..

I was losing a lot of FPS when a lot of action was happening in front of me,,explosions,dust etc etc... got fixed a bit with the last official batch but its still there

Agreed, when an enemy aircraft gets peppered or smoke fills the air my game crunches down

I encounter these stutters occasianally in Multiplayer, when a 109 is very close to me. Therefore, I suspect this is related to the netcode of CoD, when your FPS drop from 50 down to 5 in a dogfight, sometimes with smoke and then without it. Also sometimes AI bombers create these unpleasant stutters ingame druing a MP session.

superb optimisation.

Oleg insisted to model the exact trajectory of each smoke particle, including Brownian motion and integration of the Navier-Stokes equations. This gave a hard time even to the 11000 Petaflops Riken supercomputers taken by beta-testers as the average simmers' rig. Oleg was seen leaving the building mumbling about two more weeks for the optimization of the Navier Stokes integration.

Et voila what gives your stutter today.

Mostly smoke, when u shatter an enemy aircraft the frame rate goes to pieces

German A/C give me at least 10% lower fps than any British A/C. The Blenheim gives me best FPS of all the aircraft I tested under the same conditions.
