The game starts with extremely low performance (approx. 15 FPS) upon entering a world with Shaders and Mods, progressively stabilizing to 150+ FPS over 15-20 seconds. Additionally, there is a distinct micro-freeze the very first time any GUI (Inventory, Chest, or Menu) is opened.
Performance Ramp: Frame rates start very low and "climb" steadily as the session continues.
First-time GUI Freeze: Opening the inventory or a chest for the first time causes a 1-2 second freeze, which does not recur for the rest of the session.
Visual Fluidity: The game feels "heavy" and lacks smoothness until the initial caching period is over.
