670 sli microstuttering

post #1 of 4
Thread Starter 
Hey overclock.net

I checked my frametime in Dota 2 with fraps.
With 1x670 it was stable around 9
With 2x670 it jumps rapidly from 8 to 15.

Im using 326.19 drivers.
Both gpu clocks are the same.
Im using a 120hz screen

Any way to fix this frametime jumps?

Did you ever get this problem resolved on your own ? I am looking to get a second GTX 670 in the future and am always interested to hear about performance both good and bad related to the card before I got shell out another $300 or so.

I'm on a 760 sli setup and stutter free, apparently the 7 series rarely has any micro stutter issue in sli.

Is it something you actually notice or just something you saw when checking out frametimes?

I've never noticed it on mine, but I also don't remember that particular driver. Have you tried updating your driver? Or is there a particular reason you're using that older one?
