If your autosave is permanently corrupted and capping the frame rate does not work, you can skip past the broken room using a clean save file.

Ubisoft originally coded Forgotten Sands around a specific CPU clock speed. On modern hardware (Xbox Series X/S, PC with high refresh rates, or PS5), the game runs too fast or desyncs the physics engine. The Observatory puzzle relies on split-second timing; when the frame rate exceeds 60 FPS, the "trigger zone" for the pressure plate activates half a second too early or not at all.
: Only after you've moved beyond the Observatory area should you save your game and exit.

| Prevention Measure | Why It Helps | |---|---| | Cap framerate at 60 FPS before starting the game | Prevents the physics and script desyncs that cause missing levers | | Disable cloud saves from the beginning | Ensures corrupted states don't get preserved across sessions | | Create manual save backups periodically | Allows you to roll back to a working state if the bug appears | | Use a controller (recommended for PC) | Reduces input-related bugs and offers smoother control | | Avoid alt-tabbing during critical sequences | Prevents focus-loss issues that may interrupt script execution | Whenever possible, manually back up your save folder
To fix the in Prince of Persia: The Forgotten Sands , players typically need to limit the game's frame rate to 60 FPS , as running the game at higher refresh rates often prevents the puzzle lever from appearing. This softlock occurs because the game's physics and scripted events are tied to the frame rate, causing a "missing texture" or pedestal when the frame rate is uncapped.
