No I believe it's called G for graphics sync. It's the GPU does the work.
And to confirm, I played BF4 last night with the MLG guys on 3 cards and the new maps and it was complete silk with G-Sync.
Whilst im not using a gsync monitor, played some bf4 last night and i gotta say it was running very nicely. No idea if its new drivers or the latest patch, but its certainly better.Likewise, I'll try some of the vanilla maps when I get chance and see of those as as smooth.
