Hey, first post here. I wanted to share my results in breaking through the 60hz cap on 4K resolutions. As many will be quick to point out, Displayport1.2 does not support frequencies over 60hz. Fortunately this is an overclocking forum!
I was able to use the Nvidia control panel to set a custom refresh rate of 67fps (rt click desktop -> Nvidia control panel -> change resolution -> customize -> create custom resolution). Turns out that DP1.2 cable has some headroom after all. I did confirm the 67fps was truly being displayed by the monitor, and that no frames were being dropped (online tools, DSL camera approach).
I am running a 980ti SLI set up, with the cards @ 1500mhz. I have all settings on ultra. In the video I have AA turned off, but I get the same results with it on. The big thing here is that I have VSync enabled. The tearing with Vsync off was unacceptable, but if I turned it on the frame rate was in the high 40's (before the monitor OC).
The funny thing is, I took a big hit in fps after enabling VSync at standard refresh rate, but at 67hz, I seem to take little or none.
Anyway, if you are running in 4K, especially with an SLI setup, it is probably worth a check to see if your monitor can handle an OC. It made a significant gain for me. I also go similar results with Witcher3.
