The November 4 PC patch changes when shaders compile. With ray tracing previously off, S-GAME expects one recompile after updating; enabling it later queues its shaders for the next restart. A compile on every unchanged Windows launch is a different symptom. If the game closes or SteamOS reboots, use the Proton guide below.
