-  pool. Fix it with an entropy daemon (also in Requirements):
-  `sudo pacman -S haveged && sudo systemctl enable --now haveged`.
-  The two instances also share a DXVK shader cache (`dxvk-cache/`) so the 2nd reuses

+- **The 2nd instance is visible but stuck on the loading screen — and only advances
+  when you jiggle the mouse.** Root cause: BL2's `bPauseOnLossOfFocus=TRUE` — the
+  game **pauses itself whenever its window isn't focused**. In split-screen only one
+  window is focused at a time, so the unfocused instance freezes until an input event
+  wakes it. `setup`/`run` patch each prefix's `WillowEngine.ini` to
+  `bPauseOnLossOfFocus=FALSE` so every instance keeps running unfocused. (This was
+  *not* CPU scaling, entropy, or window occlusion — those were dead ends.) The
+  instances also share a DXVK shader cache so the 2nd reuses the 1st's compiled
+  shaders; `STAGGER=45` further separates their loads if a cold first run is slow.
+- **Two soundtracks at once:** each instance sets `bMuteAudioWhenNotInFocus=TRUE`, so
+  only the focused window plays audio — the sound follows whichever instance you're
+  focused on, instead of both playing together.
 - **In-game "Quit Borderlands 2 → Yes" does nothing / hangs:** the game's shutdown
   path stalls under Goldberg (Steam-networking cleanup, worse with offline mode).
   Don't use in-game Quit — close with **`./bl2-splitscreen.sh kill`** or **Ctrl-C**
