Glad you got it rocking. What video cards are you using?

Nevermind I saw it, 450s. To what capacity are both cards running?

Last ime I checked both cards were up around 95% ( within 1% of each other) and running temps were about 58--59 deg. The EVGA GTS 450 is the hotter of the two, and the Asus GTS 450 runs slightly cooler. As I have said I use EVGA Precision tool to balance both cards and find this helps. Don't know if you noticed in the above reply to "Purg" I have set Physics processor to CPU. Maybe if we all try optimising the profile settings we could get one that will work for all. Takes about 3--4 min for both cards to reach normal running temps. and I am getting good playable fps over ground cockpit "on" (London raid 45--60fps depending on activity ) with all setting on "High" except buildings and forests "Med" Very happy with the performance of the 450's would love to go to better cards but after a major rebuild the dollars ran out. Next upgrade I hope.

Also I detuned my O/C cards back to stock freq and voltages through "Prcision Tool" and "Nvidia Inspector", found they became better balanced

Cheers

I was told by EVGA suport that the cards will balance themselves. I have 2 EVGA 480s, one superclocked the other is standard. They work very well in other SLI applications, especially IL-2 classic. I may try your setup today.

Thanks.

really wow...looks like I may have to give it a shot again, thanks. q= any reason why you have triple buffering off? My cards are from Gigabyte...cant use Precision Tool but Ill assume everything the same out of box..no oc here

Please, I need some help here: on replay the engine acts as if the fuel pump has gone out and it revs up and slows down and sometimes cuts out with the prop stalled. There are other minor details presenting problems but this engine issue is the one that most bothers me. Thank you so much.

Sir,
I've followed the guidelines given in this thread.
I do get a confirmation saying that the profile has been succesfully updated.
I have checked and SLI is definitly activated in my Nvidia control panel (no force alaternate rendring, just Nvidia Recommended.
I have also checked the box for Show SLI Visual Indicator...

... and it shows that something isn't right...
I still only load up one of my two GTX 580's...

Question:
After creating this Il2: cliffs of Dover profile;
how do I make sure that it runs when I run the game?
Do I have to point to the launcher file?
Do I always have to run the Nvidia Inspector application before I start Cliffs of dover?

Best Regards,

BSS_Tintin

Hi Tintin

I think that you might be using a profile that I was using prior to the release of Luthiers code, I have since removed it, and am using Luthier's Code now, you will need to follow the new instructions for the new code in the link that I have posted here at the bottom of this post.

What I do is this: -

(1) Make sure that you have activated Sli in the Nvidia control panel and don't have one of your cards selected as "Physics" (in this panel I have selected "cpu" not "auto select")

(2) Run Nvidia inspector, activate "Il2: Cliffs of Dover" in Nvidia Inspector by selecting it and clicking on "Apply Changes". Do this before starting C.o.D.

(3) I also run EVGA Precision which shows how my cards are running (fps, temps on both cards, percentage of use both cards, etc.)

You don't need to point anything to "Launcher" it will be found automatically.

I suppose both your cards are the same model with the same V/ram (they won't work in Sli unless they are) they can be from different manufactures but must have the same V/ram.

Remember that if you update your Drivers you will need to re-import the profile from where you saved it to back into Nvidia Inspector (because the Sli code was never officially activated by Nvidia, every time a new set of drivers is released and installed, the Il2: Cliffs of Dover profile will disappear from the List).

See this link for installing Luthier's Sli Code: -

I see to also be having the same issue, the profile has been saved in inspector ok but when I load the game the sli bar does not come on (it does for other games)

Any ideas where I am going wrong?

Hi Manta,

Sorry I have only just seen your post. If you have installed the profile correctly you should be ok. just one thought, have you recently updated your Nvidia drivers?. If you have, you have to reset your control panel Sli settings (these will have changed when you update your drivers). Make sure that you have "show Sli indicator bar" ticked in the 3D settings tab in Nvidia control panel. Here's a screen shot from my system with the bar enabled.

Just downloaded the recent Nvidia GEforce driver update, and am now trying to reinstall the IL2 cliffsofDover SLI code back into the list ... but am having problems. i ran the GeForce_SLI_Profile_Tool, dated 13th Oct 2012 from Nvidia and tried to export profiles but it crashed!

.. and no profiles text file. error is - " .. has stopped working. Windows will get back to you .. etc etc"

Any help?
