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?
Input latency includes the time it takes to render the frame. CRTs have a small inherent latency advantage compared to modern LCDs but they’re not instant and that advantage is miniscule compared to the disadvantage of the lower framerate. A game running at 30 fps on a gaming LCD will have lower input lag than a game running at 20 fps on a CRT. I’m sure there are outliers that poll inputs in a silly way that increases input lag, but for most games the render time will be the greatest factor. Performance modes usually simply reduce the render time (even if the framerate is unchanged).
