MAME has the same lag with the same settings. In fact, running pc10 games in MAME you are using the same identical code paths.
Both of these impose a 1 frame delay compared to real hardware. It's necessary to avoid tearing, but you can't have both same-frame response and no tearing on emulators.
This imposes a 2 frame delay, so of course it causes lag.
