GTX 460 SLI no performance gain

post #1 of 22
Thread Starter 
So I'm running into a bit of an issue getting SLI working correctly on my sig rig. I have the cards installed and running with SLI enabled via the nVidia control panel. However, I'm not seeing any performance gain at all. I've included screenshots below. So far I've tried 3dMark06, WoW, and EQ2, no gain at all.

note: see the WoW screenshot for the nVidia overlay.

I know that I'm just overlooking something simple here, any ideas what it is?

it seems that you manually changed the SLI rendering mode? try reseting the WOW profile in NV control panel. also you have the SLI bridge installed right? just making sure.

I've just moved the second card to the 3rd slot (my board is tri-sli), no difference after resetting all SLI settings to default. What other benchmark should I try?

download 3dmark vantage. There should be a GPU score increase from one card to two

Trying Fallout: New Vegas now, Ultra settings, running great so far! I'll try vantage and 1 monitor here in a second... I took a screenshot to show the nVidia SLI bar thing, unfortunatly, it didn't show up in either WoW's screenshot or Fallouts.

On WoW's, the bar doesn't move, it's just a solid small square in the middle. The fallout bar, goes everywhere, but is I'd assume, 70-80's full.

Did you reinstall the drivers after you put the 2nd card in?
