Weird SLI

post #1 of 7
Thread Starter 
Since I got my second GTX 580 all of the games I play in SLI run at more than twice the FPS I got with just a single 580.

Would a single 580 have not been enough GPU for my CPU, a GPU bottleneck?

Ex. In Metro2033 I got 40FPS now I get 90-100

What resolution do you play at?
If it's above 1920x1080, most of the fps will come from the GPU.

Single 580 was plenty of horsepower for 1920x180.

SLI, with a 580..well..unless you're playing the original Crysis with Real Life mod or Metro 2033 maxed, it wasn't really necessary. (and Metro beats up all GPUs..sli evened the load)

(or, if you plan on 3D Vision/2D Surround/3D Surround)

Gotta love that scaling.
post #6 of 7
Presuming that everything else is truly identical between your runs w/SLI and non-SLI, there is no logical explanation for what you describe.

SLI scaling should really never exceed 100%.

And there's no such thing as 'not having enough GPU for your CPU'.

the only thing i can think of... is that the GF110 Chip might be Made to be run in SLI...

So it performs better then it should....
