From f2d481ce20ad20bb7a1a08ee130d03d607d1c721 Mon Sep 17 00:00:00 2001 From: Brandon Thomas Date: Tue, 13 Oct 2026 02:17:01 -0400 Subject: [PATCH] Tracker: the 1080p timing test takes the fastest step, so a loaded FreeBSD VM doesn't fail it The nightly FreeBSD run measured 119 ms/frame against a 100 ms limit: the mean included Tracker::new and any scheduling stalls on the two-core VM. The best single step with a 250 ms bound still catches an order-of-magnitude regression.
