How much latency do you think it adds? It doesn't hurt performance at all. It actually increases performance on both brands. Just because the N stands for Nvidia doesn't mean it's biased towards Nvidia only cards...

It would also scale very poorly in many situations.

3 6870's destroy a GTX590 in Frames and have less micro-stuttering.

Now that Awesome!

I had a GTX 590 for a short while and I noticed microstuttering in MW2. I was getting hundreds of frames per second and I still noticed it, it was horrible. Every 3-5 seconds there was a slight hiccup in frame rates (slow down speed up slow down speed up) . I also noticed the same thing in the Heaven benchmark.

In Metro, while it didn't speed up and slow down a lot like in MW2 and Heaven, it felt like I was getting frame rates in the high teens and low 20s despite FRAPS showing it in the high 30s. I don't if that's microstuttering or not, but whatever it was I hated it.

I vented my frustrations here: http://www.overclock.net/graphics-ca...eal-micro.html

It doesn't increase performance, the results are inconclusive as to whether it is faster but points to it being faster in CPU bound times, but native faster in GPU bound times.

I can't find the review I saw around half a year or so ago on x58, but NF200 was demonstrably and repeatedly slower, as shown in the best way to test it (Minimum FPS comparison), I'd personally also be interested to see someone see the latency when using a PCIe RAID card on NF200 vs without...Test with an SSD, see if it goes up a bit.

Micro-stutter (amongst other prevalent issues) led me away from multi-gpu arrays (at least for now). I had paired 6970's and paired GTX580's (and many lesser configs).

I've been quite happy for several months now with a single GTX580. It would take some very convincing data to have me move back into the multi-gpu arena (or unless I went to multi-monitors ala Eyefinity).

Their system must be unstable LOL

Edit: dips into the low 30s are obviously going to be more erratic as cards can be seen to cope with certain sections even less easily, two cards are going to perform less harmoniously and this will be more apparent when the cards cannot pull many more fps, but who plays with their cards at a struggle? Turn the settings down - simple, I've just solved the micro stuttering problem.
Micro-stutter is easily visible especially at higher resolutions.

I've had about two dozen multi-arrays and tested them for my own use (and others). It's never been about maximum or minimum FPS; My paired GTX580's for example never dipped below 90 FPS in some games and yet hitching or stutter was obvious in certain situations within games.

In fact I ran duplicate systems side by side at the same resolution, one setup with dual 580s and one with a single 580 and tested several games. Even though the single card showed lower max and minimum FPS in fraps, it was easily smoother to the eye. Even my kid noticed it.

I went through all the testing in order to justify my $1000 dollars in dual 580's. You'll note that my sig rig now only has one

I went from SLI 470's to a single 580 and although I never thought I experienced microstutter with SLI @ 1080p, the single 580 just feels a little more smooth/consistent despite having lower average fps.

Garbage article. What they're seeing is not microstuttering, but poor multi-GPU optimization on a console port that's considered graphically mediocre even on consoles.


Microstutter ACTUALLY occurs when two GPUs render frames out of sync, so rather than having each frame display for 1ms, one might display for 1.3ms and the other for 0.7ms. This gives the appearance of a low framerate, even when the framerate is high. Microstutter.

Not inconsistent framerate caused by crappy coding.
