In the mid 90's.... I remember that common opinion at the time was that you needed to aim to achieve 27 FPS +, as this was the point at which images on CRT tubes were considered to stop flickering... of course these were 14 to 17 inch CRT tubes, and a 17 inch monitor on your desk didn't leave space for much else!! I seem to remember very few had heard of Nvidia then though, 3d Voodoo and sound blasters were all the rage, and AMD outpaced many Pentiums....
