Eliminating SLI microstutter

post #1 of 7
Thread Starter 
I run a GTX 670, a i5 2500k @ 4.3 GHz with a VG248QE 120 hz.

I have the possiblity of picking up a second 670 for less then half I paid for my current one and run SLI. Most games my 670 runs 120 fps stable or gets 120 often. Mostly run games maxed out with shadows low or turned off and no AA which gives great fps.

Seeing as I love my 120 fps 120 hz smoothness I am really afraid of Microstuttering which you get with a SLI setup.

I heard running FPS higher then your refreshrate can completely remove any microstuttering you might get. Seeing as I will still leave shadows low, medium or off and no AA ill be able to get well over 120 fps in pretty much any game.

Has anyone with an SLI setup tried this ?

Cant beat 120 fps 120 hz smoothness but I am afraid the microstutter would make it worse then having below 120 fps from time to time.

When I had gtx 670 sli, I never ran into any problems if microstutter. And I'm particularly susceptible to it.

at what circumstances would you encounter microstutter? Like, low FPS on SLIed cards?

Love to have a tool that simulates frame time lag and see if it enoys me greatly. Altough some people say they have no frametime lag on their SLI.

But then again I guess people that do surround or 1440p never really achieve a stable FPS above refresh rate so they get suttering regardless. While 120 fps 120 hz light boost you might see it very easially.

I've been running Nvidia cards in SLI since the 8800GTX. I've had every iteration of GTX cards since then in multiple forms of SLI and have yet to experience microstutter. I had 8800GTXs, 280s, 285s, 480s, 580s, 680s, and now Titans. It's my opinion that when people experience microstutter it may be another problem with their system. Either that or I just don't notice it. After 6-7 years of SLI you would think I'd have run into it by now, but its just doesn't happen for me. I would just grab the second card and not worry about it. I'm sure you will be fine.

Have you also compared SLI vs single card with all the SLI setups you have done ?

Dual 780's here. Only issues I have are with BF3. Even at 120 Min frames I have some slight tearing on the screen but that's about it. Lightboost to. Every other game I play works fine.
