BF3 and SLi 560ti
Hi, recently I upgraded my PC and decided to run SLi 560ti's. However, I am running into a few problems. Such as when I was running my single 560ti I would not get any graphical issues whatsoever. Then I upgraded to the two 560ti's and I am having a bit of trouble. It seems random as far as I can tell. I put the game on high/ultra settings and either way it will do the same. It seems like every once in a while it will kind of just drop FPS. Stutter, freeze up, etc.

Either way, I'll list what I have first:

i7-2600k (NOT OVERCLOCKED0)
ASUS P8Z68-V /Gen3
16GB (Set at 1333mhz)
2x ASUS ENGTX560 TI DCII TOP/2DI/1GD5 GeForce GTX 560 Ti
1TB 7200RPM Mechanical Drive
GX600 Power Supply

Now, before I had a Palit GTX560ti w/ 2GB dedicated GDDR
but I had to switch it out for SLi.

However, I figure that even though the only difference is the actual video cards, it must be something wrong with the way that I set them up. I have SLi enabled through nVidia control panel, and it shows that everything is working fine. But I cannot believe that I am having these "lag" issues with a pair of 560ti's. Especially since I could run the Palit GTX560ti at high settings and now I cannot run in Ultra/High. Any recommendations/thoughts?

Hope you'll find a solution, cause I'm having the same problem here /blarg.gif' class='bbc_emoticon' alt=':/' /> As far as I'm concerned, BF3 + drivers don't support SLI the way it should work. I had had GTX 470 and it worked great with 45 FPS on High Settings. I've switched to SLI 560 TI and now it works worse than a single GPU. I have constant FPS drops! I can play Crysis 2 on Ultra Settings + HD Textures + DX11 Patch with 50 FPS, but Battlefield 3 is a different story. Plus I could swear BF3 is the only game where I can see micro-stuttering.

This is my rig:

- Gigabyte GA-990XA-UD3 AMD 990X AM3+
- AMD Phenomâ„¢ II X4 955 (Overclocked to 3.4 GHz)
- Corsair Memory Vengeance LP Black 12GB DDR3 1600 MHz
- 2x Gigabyte GeForce GTX 560 Ti OC 1GB
- 160 GB Seagate 7200 RPM HD
- OCZ 700W PSU
- Windows 7 X64
- BENQ E2200 HD 1920x1080

The only idea I've got at the moment is to change my CPU to a better one, but if that didn't help, I'd go mental, cause I've already spent so much money for the SLI setup and for the moment it looks like an overkill.

A 600 watt power supply is not enough for SLI 560s, especially if there is any overclocking of the GPUs or CPUs. I just upgraded from a Corsair HX750 to an OCZ ZX1000 because games would crash among other things when overclocking my GPUs above 870Mhz. Now I have plenty of headroom and have just started messing around with overclocking my CPU (very minor - from 3.1 to 3.2GHz) and GPUs from 870Mhz to 900MHz (and still going higher but have yet to try). Runs BF3 like a dream.

Not all PSUs are made equal.
I have a 650w psu and two 460's both overclocked to 800mhz and my cpu is overclocked as well.
It's yet to crash in any games ive played.


@OP:
Did you try to disable hyperthreading? I heard that causes problems with bf3.
I also am getting CPU spikes while playing this game.
