I’ve been wondering this recently. I grew up on atari/nes/snes and so of course almost all of those games (pretty sure all) are written in assembly and are rock solid smooth and responsive for the most part. I wonder if this has affected how I cannot stand to play badly optimized games eith even a hint of a laggy feel to it. I’ve always been drawn to quake and cs for that reason: damn smooth. And no, it doesn’t just need to be FPS games either. I cant play beat saber with a modicum of lag or i suck massively, but others can play just fine and not even notice the lag.
Its odd. I feel like a complainer but maybe I just notice it more easily than others?
It’s so weird to me that no one uses the term “slowdown” any more. Lag and latency meant networking delays back in the days you’re talking about. Not a complaint, just an observation that I’ve been wondering about the last few years.
But yeah, as others said, slowdown/lag was pretty common. I immediately think of the ninjas jumping out of the water in TMNT3, the beginning of Top Man’s stage in Mega Man 3, and the last boss of The Guardian Legend, but there were many more. Early 3d is shocking too, with more sub-30-fps games than you remember. Some called themselves at 20, even. [Edit: Now that I think about it, even some NES games capped at 20. Strange times.]
