Although I have only recently gone Sli I feel that I have found some things that help to get it running reasonably well.
(1) make SURE that all settings are the same in all adjustments (control panel, Invidia Inspector, etc) sometimes I have found that they aren't. (2) Try and get all cards balanced so that voltages, frequencies, etc are the same. ( I use EVGA precision Tool for this purpose available at EVGA , my two cards are from different stables and therefore not the same clocks etc.) (3) Overclocking sometimes has a negative effect (although my cards are factory O/C I have turned them down to stock settings and find them more stable) Now have smooth play after cards reach operating temps. Get EVGA "Precision" tool to show fps and card temps, also to balance frequencies and voltages. SOMEONE SAID IN ONE OF THE REPLYS SOMEWHERE THAT THE "EVGA PRECISION TOOL" WOULDN'T WORK WITH THEIR GIGABYTE CARDS, I HAVE BEEN ASSURED AT THE EVGA FORUMS THAT THEY WILL WORK WITH ALL NVIDIA CARDS, SO WILL THE ALTURNATIVE MSI TOOL. So people give it a try. THESE WERE OLD INSTRUCTIONS FOR USE PRIOR TO THE RELEASE OF LUTHIER'S SLI CODE AND I HAVE REMOVED THEM.

(4) Choose a title that is SLI supported. (Cliffs of Dover currently is not...it was broken in April)

Maybe not anymore, I see "Il2 Sturmovik Cliff of Dover" is listed in the latest "Nvidia Inspector" profile list. I have just made some adjustments to my original profile, and hello now have the smoothest play i have had with the new 285.27 beta driver. I will update the information in my post.

Glad you got it rocking. What video cards are you using? Nevermind I saw it, 450s. To what capacity are both cards running? Last edited by katdogfizzow; 09-16-2011 at 11:01 PM. |

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 Rick Last edited by RickRuski; 09-17-2011 at 01:35 AM. |

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. |

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).
