Dual Cards

Any SLI performance increase will also depend on whether the game is CPU- or GPU-bound from what I understand.

I'll upgrade but not sure yet whether it will be a new CPU or another GTX480 - just have to wait for a patch or two to get the real picture (no pun intended...) but that's no problem.

No new CPU,new GPU, it's GPU game.

Thanks - how do you know though?

Yesterday I tested.

Seeing as this on the top of the board, where did you get the idea for your concern over SLI support Tree UK? After all the possible problems that you`ve raised, and you did`nt think of this one till now.
Too bad someone else already raised it but in a completely different manner and intention.
And what have you achieved? Where are the results?

What was the point of that?

SLI support is a valid question. Dual-GPU card support is an even more valid question since this is the future of video cards.

@ Speedingbullets. If the developers, or UBI for that matter kept there user base informed instead of treating them like mushroooms there would be no need for these questions would there.

When you code an application SLI/crossfire doesn't "just work". You have to specifically use the right API's in the proper way to enable scaling. If this hasn't been done (which I don't think it has) crossfire/SLI will not work. When I say will not work what I mean is that when you enable it you will see no performance increase and often a performance decrease (due to the extra overhead of the additional card) I would expect once the initial madness has died down we'll see a patch later which adds support. You often see development teams with home-grown graphics engines have this problem. That's why when folks run crossfire/SLI benchmarks they use the well known engines to test (frostbite, ego etc.) The reason is literally thousands of hours have been spent optimizing the engines to work well with crossfire/SLI.

I can confirm that not only does SLI not work but the game acts like a 2D application and the GPU clocks will not ramp up to 3D clocks.

I can force once GPU to run at full clock speed and it almost doubles my FPS so SLI would be nice.

I tested over a dozen games and only cliffs of Dover has this issue.
