Dual Cards

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.

I would prefer more communication, too. However, the devs have told us that they are working on a performance patch which is due within a couple of days. Frankly, I'd prefer they were working on that right now!

Yes it is a valid question. I already asked it myself.
As I mentioned before, it`s the way he went about it.
Tree UK already has a limited answer on another post he created reguarding the same issue.
This post by Tree is`nt aimed at any of us anyway.

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.

Does crossfire really not work in this game?

That is sad news . I own a 4870x2 aswell ,and as i have just bought a 2500k @ 4.6 and 8gb of ram i cannot aford a new gpu at the moment .
Waiting a month or so, will in the long run probabbly be a good idea with all the preformance issues .. so no big drama

Speeding Bullets - to be fair to Tree on this one, he has been asking this since long before the game was released.

Forcing the max clocks will get you low to mid 20's over land right now so don't worry to much.

What drivers do you use?

I use the 10.8 hot fix drivers. Anything past those gets you worse performance on the 4870X2.
Lot's of people use the 10.4 or 10.5a drivers and wont use anything else but since we need

10.6 or higher for IL2 the 10.8 hot fix was nice as it was released just for 4870x2 cards
