I played the beta for 8+ hours over the last week, running windows 7, a stock 3570k and a stock GTX Titan ... On the Ultra presets, 90 degree view, with vsync OFF I was getting anywhere from 2 to 95 FPS - the game was so imbalanced and flip-floppy it was basically unplayable, I tried 4 or 5 of the latest drivers, 320.49 being the smoothest... but still rough.
The issue seemed to be CPU bottle-necking - Watching the perf. graph in game i'd see the CPU spike 100% every few seconds... it would run at 90%+ almost constantly.
Yesterday I saw an article that said BF4 performance would be better in Windows 8 (also the whole DX11.2 scheme etc..) So I bit the bullet and upgraded to W8 lastnight.Holy crap.
If you are having ANY performance problems I highly recommended upgrading to W8. Using the latest NV Beta drivers The game now runs on ultra at 60FPS - even with VSYNC on ( it actually pegs it there).
Watching the performance graphs now I don't see the 3570k over 60% ... it's solid and smooth.... no spikes or anything.
*groan* don't make me get windows 8.... IF i HAVE TO, what programs do i get to avoid the metro screen as much as possible? I just... dunno....
And to deal with the Metro apps in a quick an easy way you can either get ModernMix
which puts them in windows for you, or just get replacement programs and set them as the extension defaults.
Believe me, once the UI issue is gone, Win8 is much better than Win7. The new TaskManager alone...

I like BF4... Even if I don't plan to buy the game after the beta closes, at least I'll know it is a step forward for gaming as a whole, look at that CPU usage!
Ever consider switching to Intel to properly push those 3 cards?
No, because Hyperthreading is crap when it comes to virtualization, and even better you don't get VT-d with any overclockable Intel CPU... unless you pay $500 or more for an -E chip, which is out of the question. I've got a Haswell i5 in Anvil, but again, no overclocking since it needs VT-d.
Also, considering DX11 is capable of multi-threaded rendering, and that is likely what you're seeing there, we have no proof that the AMD chip is holding anything back. Strong single-thread performance may not be needed on the new engine that can actually pull that kind of usage, and I honestly can't think of a way to bench only the GPUs with CPUs being such a large bottleneck.
The above is my theory of course, I can't actually prove it at this time. I guess if I found someone with an i7, 7990, and 7970 also running 1080 portrait eyefinity we could agree on some settings to minimize CPU usage as much as possible and see what our cards can do.
