GSYNC monitors handle ghosting/blurring better as NVIDIA has created custom anti-ghosting logic to compensate for ghosting differences of different refresh rates. LCD Motion ArtifactsLCD Overdrive Artifacts
But with FreeSync, sometimes you get different overdrive artifacts at different refresh rates; depending on the model of the monitor. This isn't always a problem, but generally GSYNC does a better job at motion artifact consistency of different framerates (=refreshrates). Artifacts that vary depending on framerates, are objectionable to some people, although not everyone.
Here's a software (interpolated) simulation of variable framerate and blur effects -- where motion blur varies depending on framerate: TestUFO GSYNC simulation
. This looks a hell lot better than stutters for most people, but the variable motion blur effect of GSYNC/FreeSync bothers some people -- but it's often the lesser poison versus the usual stutter of varying framerates (on a non-GSYNC/FreeSync monitor).
If you are more worried about motion blur elimination, you'll want a monitor capable of strobing, and then run consistent framerates instead (framerate = refreshrate = stroberate), such as using a powerful GPU combined with VSYNC ON (or custom framerate capping instead to try to compensate for lag of VSYNC ON).
It's kind a pick-your-poison between eliminating stutters but keeping motion blur (GSYNC/FreeSync) or eliminating motion blur but keeping stutters (LightBoost/strobing/etc). To eliminate both stutters AND motion blur, you'll want use strobing instead of VRR. But you need to have consistent framerate==refreshrate==stroberate exactly matched simultaneously at all times (which is extremely hard in modern games, especially with a GPU not capable of 120fps).
Fortunately with most GSYNC/FreeSync monitors of 120Hz+, you have the option of blur-reduction strobing OR stutter-reduction variable framerate operation.
Regardless, even with non-blur-reduced (non-strobed) 120fps@120Hz, you still have half the motion blur as 60fps@60Hz -- so if that's good enough for you without strobing, you won't need to care about blurring during GSYNC/FreeSync if you keep your GSYNC/FreeSync framerates above ~100fps(ish). But if you want CRT-like zero-motion-blur ability, you will want strobe modes (Strobing/LightBoost reduces motion blur by 10x relative to 60fps@60Hz) as well as locking the framerate to refreshrate.
Blurring of low-refresh-rate FreeSync (e.g. a low range such as 30-60Hz FreeSync range) will still have quite a lot of motion blurring, although for many people it may be superior to stuttering. It's like picking your poison between this
(smooth transition betwen framerates) versus this
(stuttery transition between framerates).
