SLI not working (or so I assume)

[frankopan]

o I noticed I have been getting the same FPS in all my games be it FC3, BF4 or Metro LL with one 770gtx or both of them. In control panel it says SLI enabled but I find that hard to believe.
I did a benchmark in uniheaven and it is indeed registering both cards being used roughly the same. That means that when it comes to games it just refuses to work. Can some one tell me what's up? I have an Asus sabretooth 990fx motherboard and an 8350 fx on it.

Please help

I can say that FC3 works better in SLI than not for myself with 680 SLI. What sort of GPU usage are you seeing? It could be your 8350 is under-performing. What resolution do you use? Are you using features like MVP virtu?

Well as far as usage goes I only see that the second card is running a little colder but I can't see the takt in game. I game 1080p. I tried running games with and without the MSI gaming booster.

Right, I just installed a program for monitoring and I tried FC3. And I noticed that in FC3 GPU2 had only 10% usage. WHy is that?

Are you running a fairly current version of GeForce drivers with an updated SLI profile for FC3?

Newest driver. I don't know what you are referring to as "SLI profile".

SLI profiles are basically game specific optimizations for SLI. They are embedded in drivers (though I'm fairly sure there are ways to update or install them separately as well), and the newer ones apparently have an updated version for FC3.

Look in the 3D settings and make sure you are using Nvidia recommended settings under SLI. You could have that setting set to single GPU or some other setting that isn't working for some games. You may also want to look under the AA settings to make sure you aren't using an SLI setting there. You can assign your 2nd card to work on AA for games that don't support normal SLI. You might also want to make sure you don't have one of the cards set to be a dedicated PhysX card.
