GTA 5 - Poor SLI Scaling

[Dirk Diggler]

Seems to scale pretty well for this guy

Quad SLI giving 69fps with 17Gb of Memory usage.

 

[old gamer]

just tried for myself with 980 sli and working fine both gpu's sit at about 95%, only difference is im using 4x mssa and 3440x1440 res

Anyone with SLI and stutter issues, see my post in the GTA performance thread, link below.
Looking for other people's findings as on first testing with this tweak I'm getting very positive results for reducing SLI stutter once you head out north of the city into the countryside...

I tried this and it worked fine for 10 or 15 minutes but then crashed in the countryside when getting into a different car.

Will try without

Using the bat file to close the launcher

Without bat file

I don't really do interpreting graphs fella - what are your findings?

 

[murah]

Honestly it's counter-intuative for us SLI guys but turn off your OSD I found the game to be much smoother without the overlay on

GPU usage is varying each patch right now, wait till an Nvidia inspector tweak is found that makes it use more gpu power

I don't really do interpreting graphs fella - what are your findings?

The top 2 lines is gpu usage. Pretty much the same or higher usage when running normally without the bat

This is not OSD, just output to html file

Edit - First test without SLI and second test with.

Rounded up, without SLI FPS average is 47, with SLI the average is 70. That's around 50% increase
