Stuttering still over 3 years! Any help?

[=815=TooCooL]

I am a 60fps maniac. (considering Vsync limit)
I call it stutter when the game do not maintain 60fps and goes to 50 fps or little micropause when turning my view with TIR4.
I think the writer is a guy like me.


With E8500@3.16 , 4G ram, 8800GT, and SLC SSD setup,
FINALLY it's stutter free & 60-fps game for me even with perfect & large mirrors on.
It really is until Water=2 setting.

But STUTTER STILL EXISTS especially in Water=3 or Water=4 for me when slewing view with TIR. I don't know why it happens and thought I'd need GTX280 but I like water=2 so it should be no problem for me anymore.
It goes down to 40fps when I look down over sparkling water( in 3 or 4) and it seems like my VGA is bottleneck.

One last remaining fix wish is WARPING CLOUDS REFLECTION OVER WATER in perfect mode. Other than that, IL-2 sits in fps nirvana.

We too have little pauses with water=3 or 4
It seems Water=3 and 4 is still FOR FUTURE VGA.By the way, don't use forceware 181.20 which is new, it was so much terrible in IL-2. Stutter in every scene.
I recommned 180.48.

I too am locked solid on 60 fps due to vsync and have no stutters.

Warping clouds reflection ?

Or do you mean a shuffle back and forth ?

I see the clouds reflection in a rocking motion sometimes..... but warping ??

cloud reflections on perfect water don't move smooth like clouds themselves.
It moves like following walking robot, you know.
You can see it easily at mid to high alt.

I will go back and try the 180.48's. I was using the 181.20s for my current testing which may have made the situation worse.

I tried the the new beta 185.20's but I was getting some odd screen artifacts with vsync off, but I have to work with them some more after work. Although with vsync off on 185.20's the stutter was reduced a lot.

More testing is needed, I'll go back and try the 180.48's as well.

Ok, did a little more experimentation over lunch.

I tried several of the driver sets out there and they didn't really make a gigantic difference but I did find something that did!

I had been using the individual driver profile settings to set either SFR or single GPU.

This time I went to the harder driver switch of Single GPU or on the 174 drivers dual display mode. This effectively really does turn SLI off. Currently I am testing this with the 174.xx driver set. (174.74 I believe) ( the 174s I hear were the last to really take the 9800gx2 in to account)

Well, this did make a difference, even with Vsync on (since I use Track IR) the stuttering went way down and I think may be even gone. I don't want to get too excited because I didn't have a lot of time to test it. But after work I'll give it a real run through. So I believe this leaves me with 1 8800GTS for IL2 which seems to keep a good 60fps so far.

Now the stutters I've had in the past have probably been for a variety if reasons and that is the hard part. It might not have always been the same cause but always the same symptoms, very frustrating.

I was considering getting a new card soon, either the 285 or 295. I think this whole thing has soured me on the SLI on 1 card variety. Perhaps the 285 is in my future.

I found no difference in IL2 1946 using a 9800x2 or a 9800gtx+, I stuck with the 9800gtx+

Other games had a slight improvement.

But neither card had stutters, lets hope you've fixed it.

Can you please check 1 mission for me?

Go to Single Missions of the USN and pick the first stock one on the list, starts with a "T" (Tulagi ?) can not remember the exact name. You start in flight. I use this one as a test for stutters. Fly around for like 20-30 sec over the coast line turning and banking. Do you not get any hitches or stutters at all? Totally smooth? Before I disabled the 2nd GPU I always got stutters here with harwareshaders=1. If I turn that off it would run fine with both GPUs active.

Oh and another quick question. Does enabled Perfect mode (harwareshaders=1) have any effect other than the water?

Thanks for the help!

Our systems are similiar.

4.09 doesn't seem to run quite as smooth as the others - particularly in the heavily treed mountains and over the cities. You micht search my posts as I have proveided some detailed analysis. I don't like the perfect cloud settings so I don't use it.

1. If you are using LCD absolutely leave VSYNC on as LCD can only present in effect 60 FPS mas. Due to implementation higher FPS and vsync off might not appear as artifact free and smooth as with vsync on.

2. I allow my E8400 to multithread with both cores as setting processor affiity for IL-2 to a single core does not seem to improve anything.

3. I have tested all but the most recent unified drivers and I stick with 174.74 as it seems to be the best/smoothest/least buggy for me.

4. In NVIDIA GPU controls I have AA and Ansi all maxed out.

5. Try with one card, maximize all settings to see if it is smoother, perhaps SLI has issues.

6. I sense Senior FLYBY is lurking and will show up soon!

Ok I am using the 174.74 drivers. And I have it set to Multi-display mode, basically non-SLI.

Settings are good, 4xAA, 16x Ansio, HQ, vsync and TB on. Frames are staying near 60 and everything maxed in the .ini except Water at 2.

If I play like this it is TONS better.

The 2 keys for me for sure were:

1. NON SLI
2. Water not at 3

Although Water 3 is much better than it was before with SLI on, Water 2 still looks pretty good as well and makes it even smoother.

As a matter of fact this is the best the game has ever run.

I did notice one more culprit of pauses. The first time it loads any radio chatter up I get a little pause, but after the phrase is loaded in, no more pauses. Any insight in to this one? I've read other people have it but they just end up turning off the chatter, but I kind of like the immersion of it.
