Terminologically, all VRR already always include QFT for framerates below max Hz.TheInventor wrote: ↑05 Jan 2021, 07:02So, I assert that VRR alone is not as good as VRR plus QFT. For my 1080p example, VRR+QFT would technically be equivalent to VRR+864Hz refresh rate.
What you mean extra QFT above and beyond -- so that max Hz is still QFT.
This is already possible on some monitors if you create it in a Custom Resolution Utility and then add FreeSync range to it.
One problem is that this will only work to reduce lag, IF the panel can scanout faster. In that situation, sometimes it's favourable to raise the refresh rate support of the display, so it's not uselessly idling between refresh rates.
In that sense, a true-864Hz VRR display (i.e. 48Hz-864Hz VRR range with 1/864sec delivery) is MORE LIKELY to happen than a 48Hz-240Hz range with 1/864sec QFT -- because if a panel can refresh faster, why hold back the max Hz? Manufacturers want to be able to advertise higher Hz.
