I seem to get about the same performance after 1.2 as 1.1.

Have a look at this thread, it might work for you too, mate:

yesterday I have esperimented badly chopping or stuttering, suddenly the fps went down at 2 or 3. I have a 4000 AMD single core and a X800 PCI. May be the protection system? I heard the IL2 simmers have stuttering because the protection system.

I just finally installed 1.2 and had chance to play it.

I was really pleasantly surprised as my fps has increased too. 1.1 it was between 8 and 13 on the bridge, now it's between 15 and 25

Inside the ship before was a max of 19 now it's 35. A very noticable difference. Thanks dev team. So far so good. (at least for me!)

No crashes or oddness to report as of yet. *touching wood*

I installed 1.2 and left the fog option unchecked. I've always had the event camera unchecked, and my FPS within the sub is very high for this game, 50fps plus. On the Bridge and external camera views I'm seeing between 27 and 40fps.

I have a mid range system, and this game plays perfectly well on it and looks great. I haven't yet seen any stuttering.

This maybe a stupid question (since I have an old card) what is Volumetric FOG? The regular fog you see in a stormy night, or some other 'foggy' effect at the distant horizon??

Maybe my card does not render it. THX.:o

I have the same questions.
My system:
Pentium 4 3.0 Ghz
2 Gig of ram
ATI X1950 PRO 512 mb AGP.
Everything in the game options was turned max as was everything on the Catalyst Control Center.
Loaded the artillery mission (submarine scool) and everything was fine.
15-20 FPS outside the sub
30+ inside.
Loaded the quick mission (the one in 1945 with a Balao sub-can't remember its name) when you start at night...on the bridge 3-5 FPS!!!!!!!!
I turn off the Volumetric Fog (everything else left to the max) and the FPS jumped to 19-20.
So for me VOLUMETRIC FOG is my FPS killer.
Now I'd like to know what I'm missing with this Volumetric Fog off.
Second question:
Will I get any improvement changing the
[DEVELOPING]
DevDebugEnable
DevEditEnable
MiniDump
in the main.cfg to "NO"????

I guess no one knows, or being too busy to answer.:nope:

If I turn it off, I too get a huge increase in FPS.

I would like to know what I am missing. IF I ever had it...

It's hard to describe volumetric fog. Its more lifelife and has depth, I guess. I've messed around and unchecked volumetric fog once and it removed a light fog I was in.

The volumetric fog is more of a mist in the air that you can see and I believe it moves also. It is very hard on the processors. Also, it is in addition to the fog already in the game. Now, if you turn off the vol fog you will still get fog and it is rendered very well. This fog does not kill frames as badly as the vol fog.

Theres some fog that wont appear for me if I turn volumetric off, but with the .cfg editing I can keep it on. I was in a real light, early morning fog off the water type mist and when I turned volumetric off it disappeared.

VOLUMETRIC FOG is 3D fog, therefore more lifelike and also requires more CPU and GPU horsepower.

regular fog, as you see, impacts the point where a ship becomes visible, although it will still fade in with a fog effect. Much simpler to create and therefore less impact on your hardware.
