Virtual super resolution freesync monitor question

post #1 of 8
Thread Starter 
If this is wrong forum or not worthy of a new thread please move to appropriate place.

To illustrate my question I'll use this monitor as starting point; Acer XF240H.
It has 1080 resolution, refresh rate of 144hz and freesync range of 48-144hz.

If I use VSR will it have no effect on freesync i.e I will maintain the 48-144 hz range even if VSR has changed res to 1440 or higher? No side effects of vsr?
I guess another way to pose the question is; Is the freesync range tied to / dependt of the resolution?

Thank you for reading!smile.gif

from my personal experience on my freesync monitor, Acer XG270HU 1440p 144hz (freesync range 40-144)

FreeSync does not work at ALL when VSR is enabled. So my conclusion is that if you want to use VSR you lose the benefits of FreeSync. I get massive screen tearing in 4k VSR when freesync is enabled in crimson

Are you certain the tearing is result of VSR disrupting Freesync and not because of gpu not being able to handle workload or/and crossfire not being optimized for VSR?
Have you tried 3200 X 1800? If you have, tear or not?

yes i have tried 3200 x 1800 and 4K, and im certain freesync is just not being applied - my frame rates are above 40fps constantly and i get massive tearing.

I have tested with single Fury X and FURY X crossfire on my acer xg270hu. My conclusion is that freesync does not work at all when VSR is enabled.

I'll be sure to do that once I get a Freesync monitor, which will be in near future, so be on lookout:)

I have tried on my mg248q and looks like it works. 1920x1080 freesync on 40-144hz. At 3200 X 1800 freesync on 40-85Hz.
