better sli scaling at 1440p than 4k?

Hey giys wondering if you can help not only in games but benchmarks like valley and heaven seem to my 980 Tis in sli pegged at 99% usage however at 4k they're always around 88% mark, what's the reason for this? never to mind anyways I'm looking at the following.

What games are you having issues with? Modern games or older titles? Nothing leaps out as being a problem from your sig, so I'm thinking driver issue.

Sounds like your hitting a cap, either vsync or maybe riva tuner? I cant think what else would cause less than 100% GPU usage in Heaven, in Valley i get low usage a lot of the time but in Heaven it only dips down a little, most the time its high 97-100%.

Some games have FPS caps built in or forced vsync with a 60hz refresh rate which can cause problems but ya shouldnt be getting that with benchmarks. Give firestrike ultra a go, the first graphics test on there should hammer your cards much harder than the Unigine ones will.

I'll have to have a go tonight as I'm sure fire strike ultra doesn't peg at 99% all the way through I could be wrong

Nothing will be at 100% all the way through, as long as it actually reaching it at some point then you know your cards arent been restricted by something.

I just did a quick fire strike ultra graphics test run and my first card is just going 99-100% all the time, the second card is 95-100%. In Heaven and Valley i get loads of dips in usage as its changing scenes so i wouldnt worry about them.
