> so there are many differences Yeah, one of those is that modern stacks often deliberately introduce additional latency in order to tackle some problems that Apple IIe did not really have to care about. Bringing power consumption down, less jitter, better hardware utilization and not having visual tearing tend to be much more beneficial to the modern user than minimizing input-to-display latency, so display pipelines that minimize latency are usually only used in a tiny minority of special use-cases, such as specific genres of video games. It's like complaining about audio buffer latency when compared to driving a 1-bit beeper.
