Battlefield ignores GTX 680 SLI. Results of SLI test with SLI on/off in 3D Mark

[KennethBL]

Hi guys,

I've been having some issues with my graphic cards playing Battlefield 3. I have two GTX 680 in SLI, but on 1920x1680 with low settings, I often hit 70 or 80 fps... I should be able to keep it above 120 FPS, I would say.

A guys on Battelog, the forum of Battlefield, said that if you did a 3Dmark test with and one without SLI enabled, and the difference was slim, then you were the victim of CPU bottlenecking...

I don't know if this is a good result... Is it?

With SLI enabled: http://www.3dmark.com/3dm/1199817
With SLI disabled: http://www.3dmark.com/3dm/1199899

My problem in Battlefield is that it behaves just as if I played with a single GPU, eventhough I was playing with SLI enabled with two GPUs... Waste of $700... :-/

Please help...

UPDATE:
I just upgraded my CPU and mobo...
SAME issues... So it's not CPU bottleneck! :-(
That was 1.000$ well spend... :-(

My rig:
[strike]CPU: Intel Core i7 2700K (Sandy Bridge)[/strike]
CPU: Intel Core i7 3930K (Sandy Bridge-EP)
[strike]Motherboard: P8Z68-V PRO gen. 3[/strike]
Motherboard: P9X79 Socket 2011
GPU: 2x GTX 680 4GB in SLI
Ram: 12 GB Corsair
Windows 8 64-bit

wow looks pretty bad, a single 680 should get 70-80 fps on ULTRA settings at 1080p.

what is your system specs? (motherboard cpu etc)

Also, have you installed the latest NVidia drivers? are you using the sli bridge?

Hi... sorry for the lack of information about my rig... I've added it to my question... Thanks...

are you using an SLI bridge???

steps:
1.update motherboard bios
2. update NVidia drivers

There should not be cpu bottlenecks..... I run a slower cpu and 2 slower graphics in SLI cards and get very high fps on ULTRA at 1080p

Sli bridge is on...

I tried everything (it seems):
- Reinstalled Windows
- Reinstalled Battlefield
- Updated Bios
- Updated Chipset
- Updated Drivers
- Degraded Drivers (to 314.22 which should be best for BF3)
- Buyed a new SLI bridge
- Buyed a third SLI bridge
- Changed motherboard and CPU
- Checked for RAM errors

enable sli in nvidia control panel. This did it for me.

What cards do you SLI? And what is your motherboard socket?

My brother runs a 670 sli, on a socket 1366.

SLI is enabled ofcourse.

are your gtx 680's identical?

They were... I just sold them...

I'm waiting till the next release of 7990...
