How to benchmark Battlefield 3 ?

I want to do some Benchmarks with BF3, because its my favourite game i want to tweak some settings.

Has someone an Idea how i could do it ?

In BFBC2 i used Fraps and ran it while looking the intro of "ice cold".

What could i do in BF3 ?

So, now i managed to make some benches with Fraps and BF3 in Singleplayer mode.

Here the (for me interesting) results:




CPU is I7 950 @ 4400 Mhz, GPUs are 2 x 6970 @ 950 Mhz.
Curve 1 (blue) shows performance with HT on with 8 Threads CF is also on.
Curve 2 (red) schows performance without HT, only 4 Threads and CF on.

Its interessting, that the performance without HT is better !!!
Don't know why, could it be that the CPU is throttling somehow with HT on ?

I also get lower GFlop results @ Linx with HT on (8 threads) its about 51 GFlops.
With HT off (4 threads) its about 59 GFlops.
With HT on the CPU utilization displayed in realtemp is also only about 50 %.
Strange behavior i think.

Ok,
the next curve 3 (dotted red) is showing performance without CF, so with only one 6970 in comperison to curve 2 there is a big performance impact.

Curve 4 schows a big impact when AA is set from OFF to 4x with CF on, also a big impact. (as big as using only one 6970 without AA)

P.S.:
Today i ordered a third 6970, i will post results with 3x6970 CF next days.

Here it is, my third 6970 was delivered today.
So here is curve 5 (yellow) 4 Threads with 3xCF 6970 @ 950 Mhz.
Nice, the third card pushes performance another 30 % up ---> im happy with that setup.
