Steps to Reproduce:
Launch Minecraft Bedrock Edition 1.21.120 on Windows 11.
Wait on the main menu screen for 30–60 seconds.
Sometimes the menu is immediately laggy; other times it starts smooth and gradually becomes choppy.
Join any Realm or single-player world (including brand new worlds).
Play for 1–5 minutes.
Game becomes extremely choppy, laggy, and eventually unplayable.
Frame rate drops to single digits; camera and movement inputs stutter.
Closing and reopening Minecraft temporarily resets the issue but it returns every session.
Expected Result:
Game should maintain consistent high frame rate (120–144 FPS) on capable hardware without severe lag, as it did prior to the 1.21.120 update.
Observed Result:
Main menu and gameplay performance degrade rapidly within minutes of loading.
FPS drops from smooth levels (100–140) to as low as 5–15 FPS.
Movement and camera become delayed and inconsistent.
GPU usage often drops to 0%, while CPU and temps stay low.
Issue occurs in all worlds (new or existing) and Realms, regardless of nearby entities or structures.
Performance occasionally returns to normal randomly, then degrades again after some time.
Environment
Device Information:
• Platform: Windows 11
• Device: ASUS ROG Zephyrus M16
• CPU: Intel i7-11800H (11th Gen)
• GPU: NVIDIA GeForce RTX 3050 Laptop GPU
• RAM: 24 GB
• Game Version: 1.21.120 (Bedrock Edition)
• Graphics Drivers: Latest NVIDIA drivers (clean-installed)
• Other Details:
• BIOS checked and updated.
• Issue persists on all power modes (Standard, Eco, Optimized).
• Occurs regardless of texture packs or render distance.
• No overheating; system stays cool even during lag.
⸻
Troubleshooting Already Tried:
• Updated GPU drivers (including clean reinstall via NVIDIA app).
• Updated BIOS and firmware.
• Fully uninstalled and reinstalled Minecraft.
• Restarted and power-cycled laptop.
• Verified hardware performance with other games (Overwatch, League of Legends — both run normally).
• Disabled/reenabled GPU drivers manually (sometimes temporarily fixes the issue).
• Tested in both Realms and local worlds — issue persists identically.
⸻
Additional Information:
• The issue began immediately after the 1.21.120 update.
• Performance was completely normal on previous versions.
• It appears Minecraft may not be consistently using the dedicated GPU (RTX 3050) and instead intermittently switches to integrated Intel UHD Graphics, leading to massive frame drops and lag.
• No third-party mods or shaders are installed.
• Problem affects multiple users on similar setups (based on community reports).
