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?
You measure lag by taking the capture of a frame an input happens when it is halfway down the screen. Therefore, CRTs have input lag of half their refresh rate. For NTSC, that’s about 8ms. For PAL, 10ms.
Incidentally, a modern gaming LCD has a 2ms average pixel response time. Which is about the same as the difference between NTSC and PAL.
