momentary freezes issue

zhangke7312 · #1 02-12-2008, 11:15 PM

When I play IL-2/Pacific Fighters, I get a momentary BIG drop in frame rate in very 5-10 seconds.
With fps data displayed in IL-2, it will be 70 fps, then suddenly drop to around 3-20 fps, then go right back up. It looks like freeze a little time.

This NOT occurs only when it plays a radio speech file. It does occur in everytime, even I fly a single plane on the sea! I have done various tweaks to my system, such as disabling unneeded services, turning off hard disk last-access update, page file on another partition or disabled, etc. But this issue is stil there!
Anyone can tell you, how to slove it?

My spec:
desktop Intel Q6600
Nvidia Geforce 8800GT
2 gig ram
Window VISTA

I don't know if this is the same problem as mine. I get micro stutters every 5 - 10 seconds. The only fix I found was to set the priority of il2fb.exe to realtime. Then go back in game and it's smooth as silk. You can only change the priority while il2 is running. It's in task manager/processes (sounds like you know where). Just right click the il2fb.exe process and you'll see the options.

Thought it might be a dual core driver problem but even after installing it I have the same problem. *shrug*

Turn off "Threaded optimization" in nVidia's control panel, under the "Program Settings" for "IL-2 Sturmovik: Forgotten Battles" (NOT under Global settings) tab. See if that helps

Maybe this is not the same case but I used to have similar drop in frame rates occasionally, not frequently. It was really annoying since I do host a lot.

What I found out that my CPU load dropped when those freezes occurred looking like the IL2 was not getting enough time from CPU. Since I have also DualCore system I suspected it was related to core process handling somehow and I decided force IL2 into single core only. That solved my freeze problem perfectly - there is a nice documentation availabe how to do it:

I do not know why this happened in my setup since I know lot of people are running IL2 fine on dualcore systems without any tweaking. Maybe it is related to my MoBo (Asus P5K), but BIOS update didn't help back then.

A while back I had similar problems, and tracked it down to be sound related. I see that you say it is not related to radio speech, so it may not be the same problem, but maybe you could try to lower the audio settings just as a test.

The test I used was the track called "F4F vs G4M". When the planes are taking off from the carrier, I always got some freezes, even if I lowered my graphics settings quite a bit. I then realized that the freezes occured everytime an explosion sound was to be played. When I reduced the audio settings the freezes was gone.

At the time I was using a Soundblaster Live! card. I do now have a X-Fi sound card, and have maxed the sound settings again, with no freezes.

To quote x_Crash_x... The sound was always porked on IL2. It's a lottery: for some it's perfect (and when it is, one can hear quite nicely the sounds in 3D), and for some the sound stinks; trouble maker. Same for multicore support.
I guess the best thing that they can do is hire a professional sound engine programmer; of course, IL-2 is practically abandoned and we can hope for a code rewrite only for SoW:BoB.
Alternatively they can make a deal with the Creative Labs guys; they will lend a hand if SoW:BoB will sport AdvancedHD; at least there'll be a sure fire solution: get an X-Fi.

I had sound-related freezes also, when I got a SB Live! (what a stupid name). Even with all updated drivers and patches from Creative webpage and VIA drivers (there was a bug about the VIA-chipsets MoBo,s at that time, IIRC)

They disappeared when I got rid of the dam***ed "Live!" and got a SB Audigy 2ZS.

Did I say that? Man, I need to lay off the booze. But yeah, a lot of times freezes are caused by sound card issues... from what I've been told.

I've also heard good things from people who dropped an additional gig of RAM in their systems.

bomath · #9 02-13-2008, 10:52 PM

So the soundbanks could fit in that aditional GB?

Or maybe that quad core was secretly conducting a plan for taking over our RAM... Maybe I am the one who needs to give a pause to the stout

And the quote was "That Mk108 is porked". I enjoyed your movie!

LOL at bomath...

I personally saw a remarkable change in smoothness when upgrading from 1 gig of Ram to 2. On another note, I too have the SB LIVE! card that has caused other issues elsewhere, not IL-2 related. Hmmm, might be time to do an upgrade there....
