G- Sync will come to the Flagships first with other 2025 models following later this year. this is Nvida's implementation of VRR which adjusts Refresh Rate in real time to match a PC or game console output. support for AMD's Freesync is more common on Tv's but nowadays there is little difference. unlikely it will bring all the features found in high end G-sync Branded PC's mind you.
