Does SLI still cause input lag?

As above.

No, not for me anyway

I didn't think input lag was ever an issue with multi GPU.

SLI with some VSync settings can still result in noticeable input lag but generally input lag isn't a problem with SLI unless your getting very low framerates.

As a generalisation no, some configurations of SLI and VSync don't play nice tho.

I am pretty sure that SLI cause an extra frame of input lag vs a single GPU...

I was wondering if this has been resolved recently.

I thought that this was the case with both multi GPU and single GPU with V-Sync, hence the popularity of triplebuffering and adaptive v-sync.

Yeah but some setups with SLI and Vsync would result in extra input lag on top of that. I never really got to the bottom of why I rarely used vsync at all until adaptive vsync and 120Hz came along.

Do you not mean 'microstutter' as opposed to input lag?
