Wasn't that actually a very short lived period of time? Especially with gains up to 70%, and you had to contend with new stutters?

nvidia supported it for 17 years and amd still supports it but only on older cards

		"Supported" it sure, but I'm dubious of the "70%" increase. It was very dependent on the game being played, and the CPU being used.
