CRTs (apart from some exceptions) did not have a display buffer. The analog display signal is used to directly control the output of each electron gun in the CRT, without any digital processing happening in-between. The computer on the other end however does have display buffers, just like they do now; however eliminating extra buffers (like those used by modern monitors) does reduce latency.

Doesn’t matter. Having a buffer means either the buffer must be full before drawing, or you get screen tearing. It wasn’t like racing the beam.
