We're already seeing improvements from various manufacturers going upstream and getting used. The pull requests into the newest xserver for Kaby Lake from intel shows freesync support, so the rumors that intel will support FreeSync is true. Future Adreno, Mali-T's, and PowerVR chips also have adopted support. So even if AMD's shitty drivers are a hair behind when it comes to vsync disabled comparisons, the actual freesync technology and platform is vastly superior. nVidia will not be able to compete with the entire industry to force their standard. This is also why more FreeSync supported models of monitor are available and are still coming out, yet being the younger of the two standards. gsync is like rambus vs DDR in the late 90s. Rambus cost more and was slightly better, but it wound up dying because it was not an industry adoptable standard.
It's okay though, not the first time AMD has released an industry standard. Hell, they were the charter designers for PCISIG that designed PCI-e that took down AGP. Same reason, one was a closed standard, the other was VESA supported. Their 64bit x86 implementation is what most of us here are using, as intel had to drop theirs. The list of modern open standards that were originated from AMD is just unreal compared to their size in the marketplace. They keep good technology moving and keep the marketplace honest and affordable. No third option is going to emerge. This is it, and AMD's track record with open standards has been impressive. ESPECIALLY post alpha team, none of that 3Dnow BS.
