World

Overlay edge lines (deduped mesh edges, not full triangle wireframe) on every mesh, but only during the portal RT pass. Shows what's actually being drawn into each portal view so you can see overdraw / poor culling.

Graphs (uncheck to hide a row from the [Z] overlay)

Off = numeric values + avg only. Drawing 1800 samples × N rows of canvas paths has measurable cost on its own — disable when you want the overlay to NOT affect what it's measuring.
History window stored per row. Changing this wipes existing samples and reallocates the ring buffers.
