GTX 670 vs 2x GTX no difference in gaming

stop lowering your resolution. put it to the max and then check your fps

Max out the resolution, game settings in a couple of different games, disable V-Sync and compare with and without SLI enabled. Chances are you'll be surprised and you'll find out that it's working right.
 
You should be able to play that fine. Single GTX 670 performance.

I know 1 graphic card should be fine! and that's the problem.
@ to all guys who say I should max out the resolution, I did and I still get 51 FPS at the same place

What are your settings? If you want help, you need to provide more information. And I don't know where you got that the frame rate won't ever drop below 80FPS with two cards because it CAN. Look at the numbers posted above. The averages are typically around 50 or 60FPS. That tells me your system is probably working fine.
 
Weird, look guys I SWITCHED OFF SLI IN NVIDIA PANEL, opened the game, put all setting MAX -ultra, max resolution AND STILL GET 51 FPS. What' s wrong? It seems, BF does not see the second graphic card



Yes I did turn off V-sync

I'm going to ask you a stupid question. Did you attach the SLI bridge to the cards?
 
Please, for the love of god, I hope you're trolling. If not, again, please, for the love of god, buy a 23-24" 1920x1080 monitor, and then you would be utilizing the power of these cards. You're not even making the cards break a sweat at that shitty resolution (1280x1024).
 
I got a bridge on those cards.

@Mr.Stryker
If you watched carefully, I have already bought 22' Monitor Full HD, 5MS, 1920x1080



V-sync OFF. Sorry that I had to post picture from mobile phone, but I wanted to show you that SLI is active while I am playing, and fraps didn't catch this on pct.

is vsync off in your drivers? and your restating the game after each change correct?
 
Have you tried to use a program like MSI Afterburner to see if your second gpu is being utilized?
 
If you are worried about one singular spot, well don't be. It is a game and the reasons are myriad, especially in a multiplayer game where you have netcode to deal on top of everything else. If you see high frames elsewhere it is likely some other bottleneck like the CPU. Easy way to check is to run the CPU overclocked - or underclock if you don't like to overclocked - to see if there is a difference. First rule of diagnosing is to eliminate all the other variables before you try to fix something.

Easy analogy is a water hose, you can attached a fire hose to a normal faucet and give it great capacity for flow, but you will not change the flow until you upgrade the ability of the faucet to provide that flow. I now you upgraded your montior but @ 1080p your are still putting out a cigar (versus you previous cigarette) with the hose, it doesn't matter how big you make it, it can't put it out any faster then it already did.
 
@Filter
Ye V sync is off in Nvidia panel, and I restart game, every change

@nanotube
I think yes

@D-Wiz
Nop, I notice almost everywhere FPS drops, It is as if the BF3 didn't saw the second GPU, cuz when I turn SLI OFF it is no difference

Guys, but what about my graphic cards, does it matter that one of them is already OCed by Gigabyte to 980 MHZ, and the another 1 has original tacting on 915MHZ, does it have something to do with it?

Gigababyte OC tacting at 980 MHZ - http://www.techpowerup.com/reviews/Gigabyte/GeForce_GTX_670_Windforce/

What am I supposted to do if the OC matters?

I marked something in circle. When I put cards in SLI I didn't instal the drivers form second card, is that bad?

Multiplayer and that low res and SLI? CPU bottleneck, and a big one at that.
 
22" at 1080p is still pretty small for those cards in SLI

I run a 27" at 2560x1440 with my two 670's and it's a great experience for most things.

Resolution is not the issue now.

Alright. Are they both Gigabyte ones?

Sorry glazed over and we don't have POV brand in Australia so I didn't realise.
They use different pcbs. Not usually an issue however it could be the reason why you are getting terrible scaling.

Edit: A long shot, however you could make sure they are flashed with the same bios if possible.

I noticed your running nvidia driver version 301.25. Try a clean install of 304.79 betas.

Have you tried running benchmarks? Other games? Unigine Heaven runs? You'll easily see if SLI is working or not. BF3 is not devoid of bugs at all. Also, you should get two exactly similar GPUs for SLI, having one overclocked and another @ stock is a bit of a waste since you'll be limited by the slowest card (although Gigabyte's OC is small and it shouldn't matter too much here).
 
3d mark 11 benchmark says I am using 2gpus. I even used Evgra precision to check if the bf3 uses 2 gpus and it does. 60 % usage of cards and I still got 50 FPS ? For f**k sake.
 
I doubt it but you can try another PSU if you like. But before that, do benchmark runs with SLI on and OFF in 3dmark and Heaven and you'll see if your SLI is working or not by looking at your scores.

You probably just picked a bad spot in the game. Why don't you do some single player runs? Or try another spot on another map? "Rock and a hard place" is a great benchmark for example

I strongly suspect his SLI setup is working fine. If he was playing at max resolution, with max settings, 51 fps isn't too far off the mark. His scaling sounds somewhat shot, but I do believe the SLI is working as intended.
 
Ye, but explain me why the usage of cards is only 70 % on each one? Why it does not go up. I'd like to set the usage of cards at 100%, so I am sure fps would go up
 
Genuine 100% GPU usage is not practically feasible, not even on single-GPU solutions. Don't worry about that.

I believe you're still hitting a CPU bottleneck at that resolution. I had a SLI GTX 670's and only got 60-70% usage on both of them @ 1920x1080. When I hooked up my other monitor which is @ 2560x1440, they both pegged at 99%.
 
Then guys, explain me, why do I get 50 FPS on empty server? While I should get 150 fps...

Cerativ, once you go below a certain resolution, on ANY card, it will be limited to the CPU, which bottlenecks the GPU. That is one reason why you won't be at 600 fps at 1024x768. Thus, the video card doesn't have to work very hard (much less than 100% usage), since the bottleneck is at the CPU. That is why so many folks here are telling you to OC that sonbitch.

Simple to understand, really.
 
You may be having serious scaling issues. Also, possible driver problems? Something in your system would be bottlenecking, and I am inclined to believe it is CPU related or resolution related. What are your other system specs, including operating system? Do you run alot of background processes while gaming?
 
Ye, but I didn't experience more FPS in another games as well. This is not only about BF3 game. Neither of my games got better with that sli...
 
I would turn everything back to default in your UEFI/BIOS, format, reinstall everything and see what happens. If you can't solve it in four pages of posts, then maybe starting from step 1 isn't a bad idea.

Oh and if you have the Witcher 2, try playing with Ubersampling on. If you have good FPS there, then it's working.
