Someone got to test if freesync flickers are severe fps drops like gsync does!
Not to mention to find if it has any surprises hidden!

Anyone wants to try it out, FreeSync is in the beta drivers 15.3 and only works with single cards(AMD)!

Go read the bit about ghosting in this review.

As far as i can understand - freesync has noticeably more ghosting than gsync. Something to do with voltage tuning. I wonder if this is just a defect of LCD and would go away with OLED?

Also, in that review there is some explanation how gsync works below its min cap. While freesync just turns into vsync.
However gsync is known to flicker if the fps drops very low, like in loading screens and stuff, while freesync will never flicker.
The max cap vsync isnt an issue for either, as everyone here knows to cap your global fps a few frames below the max refresh on any variable refresh screen.

I keep thinking that these minor defects and differences of gsync/freesync would disappear if we moved from the shit LCD on to some OLED, as oled is good enough to even hold an image @ 0hz, thus making a true fps=hz variable refresh rate possible with a 0-whatever range. Funny that freesync spec minimum is 9hz, while gsync could go as low as 0, according to an interview with Tom Peterson on PC perspective.

FreeSync quality will depend on the manufacturers' components of choice. This round they apparently decided to skimp out. So much for 'free'.

gsync is known to flicker if the fps drops to 0 specifically. calling that "very low" can be misleading. ;)

Didnt know that its only for exact 0 fps.
Do you have the source where you found that out by any chance?

I read it here:
...we fired up a game that we knew could instantaneously swing from a high FPS (144) to a stalled state (0 FPS) and back again. As it turns out, EVE Online does this exact thing while taking an in-game screen shot...
...Again, this only occurs when games instantaneously drop to 0 FPS, and not when those games dip into low frame rates in a continuous fashion.

however the word "flicker" get tossed around easily, so you could be referring to a possibly noticeable brightness variance (depending on monitor) as the refresh rate doubles / triples and quadruples when the fps dips below 30, so to maintain the widest VRR range possible, as described here:
