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?
“Lag” does indeed come from network/signal theory and does indeed refer to networking. Been a minute, but I want to say lag is the round trip delay and latency is A to B but don’t quote me on that.
That said? Nobody cared. “Lag” was always the time between action and response. Some of that might be input delay. Some of that might be display delay (which has always been over-exaggerated but…). And a lot of that really was network delay. These days it tends to be more rendering/logic delay because people who are playing on shitty internet connections know it.
