Good high-resolution specialized video-codec based (H.264 / H.265) digital FPV video systems like Walksnail or DJI hover at around 30ms of latency glass-to-glass. Analog systems used in racing are at around 15ms glass-to-glass, with most latency coming from the camera's image processing, but would be a bit non-standard to train or build a system around without transforming back into the framebuffer/pixel-value domain, which would introduce some slight degree of extra latency. There's a rather unique uncompressed transmission system called HDZero which roughly matches analog latency.
