not what I expected. guess im not upgrading.
 
yeah known about for a while if you have decent cpu already get a better gpu or save money for another year.
 
I'm surprised they didn't try it with an older Core 2 Quad, or even an old X2 or something, just to see how low you have to go before the processor becomes a bottleneck. I imagine there are quite a few people with Q6600 etc that would like to see how using an old CPU affects the game.
 
pentium G840 in my works pc plays the game great with a GTX 285 @ 1080p

admittedly not at highest settings but its more than acceptable

This is quite interesting really. I've read a lot about BF3 being coded for up to 8 cores/threads, but if it shows no improvment, it's just a white elephant.

Theres a HUGE difference between CAN and NEED's to use 8 threads. Its generally better to run 8 small threads. As always, the first games that were multi-threaded in general just had one huge thread that used 97% instead of 100% of one core, and split off say the sound thread onto another core, for years actually we had one strong thread with little bits they broke off. In the last 4-5 years we've seen a very gradual introduction of games coded to scale very well and use a similar amount of power on each core, engines that can split a thread incredibly effectively across two cores.

BC2 could use 8 threads, it didn't NEED to at all, however it was capable of using 8 cores instead of 4 cores slightly more heavily.

There wasn't a chance in hell BF3 was going to be CPU limited, unless its a game like FSX or Supreme commander/Total War, games just aren't CPU limited.

Not suprised at all to be honest, considering the previous techspot bench results of with the various CPU with a GTX580 at 1920 res, an even a i3 2100 is fast enough. When it is not CPU bound in a game, it is NOT the extra cores that would make a difference in frame rate, but the architecture of the CPU and cache size. The benech result above simple prove that on the i7 2600K, even two cores is fast enough and would not be slower 1 or 2 extra cores on the same CPU that has the same architecture and cache size. drunkenmaster has pretty much summed up what I've been saying all along...a game that CAN USE 4-6 cores doesn't mean the game NEED 4-6 cores. The game's support for using 6 cores would however benefit slower 6 cores CPU such as Phenom II X6 in helping reducing bottleneck when using Crossfire high-end graphic card comparing to on a Phenom II X4.

In terms of minimum frame rate, I would suspect the i5 2500K/i7 2600K would still be quite a bit higher than other CPUs such as the i3 2100, Core2Quad, Phenom II X4/X6 even if it is not CPU bounded. While an older quad-core CPU isn't going to bottleneck single GPU graphic card in BF3, if they are upgrading from an old quad-core to a SandyBridge, the extra performance and frame rate would be from the better cache size and faster architecture, and has little to do with CPU usage.

Remember though that Going Hunting, whilst impressive, is primarily an 'on-rails' jet mission that doesnt have an awful lot happening in terms of cpu calculations. Planes will spawn it at set interfavls, theres not much in the way of ballistics to calculate etc.

Id rather they had benched a regular infantry mission with lots happening...
