Comment on Why do low framerates *feel* so much worse on modern video games?

True, but even that is higher than the latency was on the original systems on CRT. My previous comments were specific to display tech, but there’s more to it.

Bear in mind I can’t pinpoint the specific issue for any given game but there are many.

Modern displays, even the fastest ones have frame buffers for displaying color channels. That’s one link in the latency chain. Even if the output was otherwise equally fast as a CRT, this would cause more latency in 100% of cases, as CRT was an analogue technology with no buffers.

Your GPU has a frame buffer that’s essentially never less than one frame, and often more.

I mentioned TVs above re: post processing.

Sometimes delays are added for synchronizing data between CPU and GPU in modern games, which can add delays.

Older consoles were simpler and didn’t have shaders, frame buffers, or anything of that nature. In some cases the game’s display output would literally race the beam, altering display output mid-“frame.”

Modern hardware is much more complex and despite the hardware being faster, the complexity in communication on the board (CPU, GPU, RAM) and with storage can contribute to perceived latency.

Those are some examples I can think of. None of them alone would be that much latency, but in aggregate, it can add up.
