# CODM Rebirth Island map lag + worsened sensitivity (TAC)

The Rebirth Island map (introduced in CODM Season 4.3) runs significantly worse than the older maps in TAC — frame drops mid-firefight, sensitivity feels different from your normal binds, and aim-down-sights (ADS) tracking feels off. Reported framing:

"alguno mas tiene mucho lag en el mapa nuevo de rebirth, es casi injugable y la sensibilidad peor"

Symptoms specific to Rebirth:

  Average FPS drops 20-40% on Rebirth vs Standoff/Crash/Nuketown.
  Mouse sensitivity feels heavier — same DPI, but smaller perceived movement.
  Sometimes screen tearing/stuttering at the same FPS that other maps display smoothly.
  Multiple users confirm — not isolated to specific hardware.


Root cause: Rebirth ships denser foliage + new water shader effects + a larger draw distance than older maps. CODM's emulator render path doesn't have specific optimizations for these effects (yet), so the GPU compositor in TAC has to do more work per frame. The sensitivity feel changes because the engine's input poll rate drops in proportion to FPS — at 80 FPS instead of 120, every mouse pixel translates to a slightly different camera angle.
