Battlefield 3 is unplayable @ 2560X1600 ultra settings on Zotac Nvidia GeForce GTX 590 Quad SLI

[Randomly]

Well I have installed Battlefield 3 on the computer of mine. as I am trying to play with 2560X1600 ultra settings but I am not able play into 64/64 multiplayer. Let me know if you are facing the same problem which you have mentioned over here. I am waiting for the prompt replies of yours in this particular matter. Thanks a lot in advance.

In order to get the root cause of the problem you have to answer following questions.
Which operating system do you running? What is the hardware configuration of the computer? Do you have done any changes on the computer? Let me know if you are getting any error message on the computer?

I have kind of single player experiments and VRAM is maxed at the ultra settings of 2560x1600.
Following are the suspects are the

1. Resolution
2. MSAA
3. Ambient Occlusion.

To get the MSAA you have to lower down resolution or ambient occlusion. In order to get higher resolution you should leave MSAA or ambient occlusion. MSAA is the biggest expensive factor for the gaming.
Another thing which I would like to recommend over here is that SLI is working at master / slave pattern. The master is supposed to send the frames and slaves is supposed to render. As the slaves are supposed to rendering with frames then it will send back the results to the master. The master solves everything and presents the output the screen and same process is repeated.

After doing quick googling I have come to know about that each GPU is supposed to manage frame buffer memory and there will not be any mirroring. GPU1 will use MEM1 and same thing is applicable for GPU2 , MEM2 and so on. If the thing is not working for you than 1 GPU which is having the 1.5GB frame memory buffer is trying hard to render @ of 15 FPS.

If you are not able to solve the issue than you should get the latest version of the drivers and install the same on the computer of yours. if still the issue is seems to persisting than you should contact the technical support team and get the further assistance on this particular matter.
