Hello,

I recently upgraded to 3 way SLI last night... and while my FPS have jumped noticibly for the better, I'm getting a lot of stuttering while playing (didn't have any issues with just 2 cards). I have no idea what is causing this. Any thoughts or ideas would be appreciated.

Also, I am using the latest drivers.

(using GTX 480s - why? Because I have a PCIe 2.0 MB, and the cards are only $100 on ebay)

Thanks

Might be due to variance in frame times. Does it happen with adaptive V-sync enabled?

This sounds like a micro stuttering issue, not much you can do to fix it other than run fewer cards. Make sure the game you are playing is enabled to run SLI mode, and your CPU can bottleneck those cards which can cause stuttering. Try running turbo on your CPU if you have that option is Bios, that may boost the ghz and allow it to run without stuttering.

I've tried it with V-sync enabled, and disabled - no changed except my FPS drops with it enabled.

with the 337.88 driver, WildStar is SLI enabled, and I'm also playing BF3. That shouldn't be the issue.

I'm not worried about my CPU, because my FPS jumped noticibly, and the 3rd card scaled very well. If it was a CPU bottleneck, my FPS wouldn't have gone up as much.

I'm not sure then, I use to run 3-way sli GTX 260s and had micro stuttering in several, if not all of my games. I fixed it from following an article.. unfortunately the more cards you have then the more frame latency there will be, with that being said it is not really very noticeable on the 600 series, the hardware based metering does a great job of keeping the frames locked.

I went into Nvidia Control Panel, and enabled "triple buffering". This seems to have mostly fixed the issue. There's still a little stuttering, but nothing like before.
