Buying a new motherboard that has pcie 3.0 won't do you any good: source! Running two 7970 on x8 lanes won't bottleneck them in any measurable way. And I am talking about performance here, not to mention microstuttering which is a whole nother problem. Crossfire/SLI + eyefinity/surround while generate microstuttering because of the variance of time between frames. This kills smoothness and playability. There really isn't any good solution to your problem other than selling you second card and just use the one. Both nvidia and amd have a lot of work to do when it comes to improving their drivers. I am sure this problem is not at the top of their list, so don't get your hopes up.

Listen to the above poster, the problem described has nothing to do with PCI Lanes or speeds, it sounds like a classic microstutter problem.

Maybe driver related, maybe helped by capping FPS and maybe helped by changing frame pre-rendering to 0 (or 1) in either the games (BF3 has a console command) or with a tweaking tool.

so not sure what exactly, may be the new drivers from the 15th/16th of feb, or all the hot fixes, FPS limiting, registry tweaks and some minor overclocking in the video cards, but I finally have a sustained FPS with no issues with everything on ultra except for MSAA and HSAO off, and it looks great, runs smooth and no microstuttering, some slight frame distortion when moving really fast, but thats to be expected with Vsync off. It runs smooth,plays smooth and feels smooth, finally feel like I am getting my moneys worth.

here is an image with my FPS and settings set up to. (I capped fps at 55, felt somewhat smoother and someone else on another forum recommended it w/ msi afterburner)



and this is some in game footage while flying



Works great, and i am really happy with the results, Thanks for those who helped in this thread and the many other threads I read on this forum, much appreciated.

(Side note) the second pic, what does the graph on the left mean with that weird curve its doing?

Hm nice that you're not having the microstuttering anymore. Do you still have it in other games or is it completely gone?

Where did you get that Graph ? *want''s one!*

Looks like Framerate for me, just not in "picture per second" but in "time between pictures in milliseconds". So i assume you had a FPS drop when the green curve was high ? (and why is there a seperate CPU & GPU graph... no realy where did you get that tool?^^)

its actually built into Battlefield 3 so you can see your CPU and GPU usage in game, only available in BF3 though and I think BF:BC2, its pretty handy, too bad msi afterburner doesnt implement something like that.

little offtopic now.... but.

They will implement something.. well i heard something bout *plugins* so you can do like anything you want to ;)

that would be nice, I have a new found love for msi afterburner, just not sure how far I can push my 7970s when I overclock them with it, Also Question, When Overclocking in crossfire, do u overclock both card individually equally? or do u just overclock 1 and set the other to sync?

I would use the option on synchronizing settings for both gpu's. Keep in mind that although both your cards can reach a certain clockspeed that in crossfire they may not.

That is on a wery low resolution, according this article even GTX 480 SLI - 5760x1200 will have +10% performance hit in high resolution 16x/16x vs 8x/8x.

I'm starting to regret my Z68 x8/x8 board, only pci-e 2.0 :(

I has one 16x slot and the other slot is up to x8 so I guess it gives me x8/x8 then.
