Do dual GPU cards need SLI profiles?

post #1 of 3
Thread Starter 
I currently have an SLI setup (see below for details) and I'm under the impression that not every game will take advantage of SLI due to the lack of an SLI profile, is that correct? If so, can anyone tell me how single PCB, dual GPU cards like the 590/690 differ? Do they pose the same "issue"? Thanks very much!

Maybe what I was asking was poorly worded or simply considered too n00bish to elicit a response but for anyone else who might have been wondering, the answer to my question is yes. A single 590/690 will still need SLI profiles to make use of both GPUs in games.

Everyone is just obsessing about 690's and 670's right now wink.gif

Glad you figured out the correct answer. Dual GPU cards work IDENTICALLY to SLI'd single-GPU cards in every way, shape, and form.

The good news is, I've been running SLI or dual-GPU card for many years now ... it's really quite rare to stumble upon a game or bench for which an SLI profile doesn't exist (and hence SLI doesn't work). Typically this only happens with pre-release Demo's or Beta's. By the time any remotely major-release actually comes out, nV has already added the profile, at least to the driver package that immediately preceded the release. If not, it's in the next beta driver release, typically within a week of the game's release at most. The SLI profile for Diablo 3, for example, has been in the WHQL drivers for some time now.

Furthermore, there's various tricks that can be deployed to make SLI work even when there's no profile for that specific game ... such as using nvInspector to add the unsupported game's .exe. to an existing profile for a similar game (like, if the engine is Unreal 3, you add the new game's .exe to the UT3.exe profile, that kinda thing).
