The overlay's rate, lows and graph were fed from the game's present calls. With the replay on the submitting thread, work held for an event is replayed with the next frame, so the calls come in uneven steps although each frame costs about the same: 36 and 9 ms apart in turn in a village, a sawtooth in the graph and a 1% low of 14 fps, while the pictures went out 19.7 ms apart on average and changed by 3.9 ms from one to the next. The present thread now reports each picture (perfmon_shown) and the overlay takes its intervals from that; the game's calls are used only where no present thread reports. A picture that arrives early now waits until seven eighths of the recent interval have passed since the one before (vk_backend.c pace_smooth, NX2NAVI_PACE_SMOOTH, on by default; not with frame generation). In that village the change from one picture to the next went from 3.9 to 3.0 ms at 51 fps both ways, in a graveyard from 3.1 to 2.6 ms at 54. Co-Authored-By: Claude Fable 5.2 <noreply@anthropic.com>

// Format: "key = value" lines, '#' or ';' at the start of a line begins a comment, [sections] only group. A key is a
|
|
// variable name without "NX2NAVI_" (an optional NX2NAVI_ prefix is accepted), case-insensitive. A value is the rest of the

// Live settings: cfg_set changes a value in memory (readers see the new pointer; the old string is kept, so a pointer
