Setting up Sli

Also are you leaving "Inspector" minimised or are you shutting it down??. I find that I must check my settings each time I go to start COD, "Inspector" seems to reset to "Global" settings when shut down. Don't know if you are running your cards over clocked, mine were O/C by factory but I have detuned them to standard clocks each time and find them more stable. Are both your cards from the same manufacturer??, Mine aren't and have different clocks, that is why I use EVGA "Precision Tool" to set both cards to same clock speeds ( Standard, no O/C). You can also use "Inspector" to set your clocks, Just make sure that you "unlock" minimum and Maximum. With "Precision Tool" you can Syncronise both cards clocks. These small adjustments I have found seem to make small improvements each time. EVGA Precision tool works with all Nvidia cards I have been told by EVGA, also MSI tool. The "Profile" that I'm using is only a work around until hopefully the developers and Nvidia come up with an "Official" profile, and only seems to be ok for some and not all (especially those with 3+GPU processors in Sli). I have just installed the latest Nvidia "Beta" drivers 285.38 but haven't had time to test them properly, at this stage I haven't seen any improvement from "285.27 Beta". Check and see if both your cards are running at the same temps or within 1--2 Deg of each other, if not this will indicate one card isn't operating properly in Sli. I'm getting fps over land 40--60fps depending on activity and 60--90fps over water. What Vram do your cards have?? anything less than 1gig with each card and you probably will be struggling. Each card must have the same amount of Vram to run in Sli (you can't mix a 1gig card with a 512mb card even though they are the same model, it won't work with Sli). This is information I have recieved from "Nvidia SLI Club".

Hi friend, thks for fast reqest. I have got 2 nvidia GTX275 ZOTAR the 2 grapich cards are the same... the memory that one grapich card, VRAM is 896MB DDR3...

But I have other Pc with single grapich card to GTX 465 with VRAM 1024MB - GDDR5 and motherboard P5K premium (5 yars old) with 4gb Memori Ram DDR2 and intel core quad duo, at 2,6ghz and this pc the game run better...

I hope that Nvidia and Luthier make profile to SlI, it is very important...
