The other great thing is in recent years a lot of the top manufactures are paying a lot of attention to keeping input lag low in game mode. It was so annoying in the past when manufactures gave no fucks. I can honestly see input lag of next years sets clock in at under 16.67ms (1frame @ 60Hz). I have low input lag monitor and I have no issue switching between these new UHD displays that have low 20ms input lag and between my "tournament" monitor for fighting games. I thank reviewers paying more attention to input lag along with leo bodnar for creating a easy device to test for input lag for this shift in manufacturers attitude.
The thing that a lot of people seem to forget is that VRR means that you can eliminate V-Sync lag too.
So it's removing latency from the game side of things too, not just the display side of things.
A VRR display with 30ms latency has lower input lag than a fixed refresh display with 20ms latency using V-Sync.
But ideally input lag is always going to be as low as possible. G-Sync monitors are typically <5ms.
SLI Volta Ti is what I plan to go with.
Along with top of the range set (about 10K budget) that supports 4K @ 120Hz and good implementation of VRR.
Kind of defeats the purpose of using a variable refresh rate display when you're going to have 'microstutter' and an extra frame of lag with a multi-GPU setup.
VRR is harder than people realise to correctly implement. Especially on an HDMI context where audio sync is involved.
You say that like G-Sync displays don't already support audio.
OLED eliminates a lot of the issues with VRR too.
OLED should not have problems with very low refresh rates so they should theoretically support native 24-120Hz or even lower than that.
No need to worry about variable overdrive with OLED's <1ms response times.
