3d with SLI enabled strange juddering
I noticed something strange and i'm not sure if it has just started happening or not.
With SLI enabled, although the frame rates are higher in 3d mode in most games I have started to see juddering in the graphics.
It affects some games worse than others but I see it most when doing a pan from left to right or vice versa.

Would anyone with an SLI rig mind testing this for me?

Disable SLI, enable 3D and go to the nvidia 3d test screen.
Look carefully at the Nvidia logo especially when it pops out of the screen.
Then, enable SLI and do the same test. The logo seems to judder and have strange hiccups. It's not smooth.

The same thing is happening in most games i'm playing but going for a helicopter ride in COD modern warfare is the worst of all.

I have 2 x gtx295 so I pulled one of them out and got the same result.
Also tried the last three lastest drivers on vista and a fresh install of win 7

Is this happening to anyone else?

Cheers,

I'm getting something a little wacky with SLI enabled myself. It's a sort of flashing, happens once every 5 to 10 seconds. I turn SLI off and it goes away.

Thanks for your reply.
What card are you using?

I thought it might be because i have my system overclocked so I took that all back to standard settings and I can't stop it from happening.

Anyone else noticing this?
