Macro-stuttering is reported as a 1-2 seconds pause, sometime as two 1-2 seconds pauses following each other at a fraction of seconds, when playing Il2PF.

Macrosturrering incidence is quite low: 15- 20 minutes... http://forums.ubi.com/groupee_common/emoticons/icon_mad.gif...anyway it is a really annoying event.

According to il2 users reports http://forums.ubi.com/images/smilies/10.gif
Macrostuttering occurence has been associated to some events:

- the first burst fired, often by an AI controlled plane, in any engagement.

- the opening of Radio transmission in any engagement.

- the sighting by any flights of enemy opponents or the sighting of assigned ground target.

Although different strategies and setting have been suggested to fix macrostuttering problem, all them lead, at their best, to a reduction of macrostuttering occurence, while we failed to achieve a clean Il2 performance, completely free from Macrostuttering events.

Of course player could easely co-exist with the problem, if we could limit macrostuttering occurence to cruise fly.....

Unfortunately MURPHY RULE apply to macrostuttering events occurence too.

As a consequence macrostuttering occurence is always associated to player most critical moments:

- http://forums.ubi.com/groupee_common/emoticons/icon_eek.gif When you are acquiring in your gunsight an opponent plane, after a long engagement....

- http://forums.ubi.com/images/smilies/mockface.gif When you are vertically diving to acquire a ground target, or near to strafe an enemy columns....

- http://forums.ubi.com/images/smilies/blink.gif When you are near to touch CV deck, in an emergency landing, with your plane sevearly damaged, and in bad wheather conditions.


Well guys, I cannot say how you manage this trouble.....

With my Athlon64 X2 4400 GHz, I got some benefit disabling one of the two processor cores: anyway I only sucessed to reduce macrostuttering incidence !!!!

May be Pentium users are more lucky .....


After trying, with few or any result, most possible setting solutions- Il2 configuration, Graphic processor setting, Athlon64 dual core setting- It's perhaps time to give up and concentrate on a new strategy:

You tried what I described here, including installing the X2 drivers ?:

This is the same solution.

Stutters happen when the computer has to load new textures, for example gun tracers, or water splashes, or loading large textures (possibly LODs of planes) when planes fly by.

HERE IS THE SOLUTION

Open IL-2 Setup. Opent he Video Tab. Select "Safe Settings" on the drop down list. Save and exit. Open Il2 Stab, if you have it, Make sure your resolution is still what you wanted and start IL-2.

Start a single engagement where you fly MC-202 against 2 B-25s or something in the Quick Mission Builder. Do your head on pass and see if your computer stutters when you get within close range and attempt to fire at your target.

It should be fixed with safe settings http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif .

Another possible source of stutters (it was with me, anyway) is swapfiling. Look for your hard drive light when your screen stutters, if it's on you're swapfiling. The easy fix for this for me was going from 1gb to 2gb ram. http://forums.ubi.com/images/smilies/16x16_smiley-happy.gif

I left behind my old
GIBABYTE Nvidia G70 GeForce 7800 GTX 256MB
for a couple, SLI connected, of new
XFX Nvidia GeForce 7900 GT 256MB DDR3 a couple of weeks ago.....

Other relevant PC components:

MB ASUS A8NSLI DL 4DDR400-2CH 2PCI-E16X La
AMD Athlon64 X2 4400 GHz
Corsair Value Twinx 2GB (1GbX2 MB) DDR PC3200 RAM
2 HD SATA 74GB 10.000RPM 8MB cache

Graphic processor driver, (nVidia 84.21) & BIOS, (Phoenix AwardBIOS ver 6.00PG) have been updated to last cestified available versions....

With most program but Il2 ver4.04m my PC is rocking !!!!!

I disabled extensions in Il2 Audio setup menu:

"ENABLED EXTENSION" OFF IN IL2 AUDIO SETUP PAGE.

I seems like performance has been improved !!!!

Of course an extended testing time will evidence if that is true.

The first salvo stutter or first radio stutter sounds like a soundcard problem for me. Do a test - disable sound in il2setup and check if the stutters are still there. If not, You know what to do - turn the sound on but experiment with different windows sound hardware acceleration settings and different game sound engine settings.

Good luck!

I'm going on in my test with:

"ENABLED EXTENSION" OFF IN IL2 AUDIO SETUP PAGE.

The results are interesting......

It seems like I have no more Macrostuttering episodes: some microstuttering is present when dropping bombs onto ground targets....may be due to upload of explosions related new textures.
