Severe memory usage & FPS drops on latest Bedrock version

Extreme RAM usage (≈88%) and large FPS drops (500 → 40 FPS spikes) occur only on the latest Bedrock update. Previous versions run perfectly (except for 1.21.120 which was somewhat choppy.)

Memory usage jumps to ~88% immediately after joining an official server load stays high.

FPS fluctuates wildly (500 → 40 → 300 → 45→340 → 50) every few seconds).

Downgrading to an earlier Bedrock version (pre1.12.120) completely resolves the issue.

PC Specs

  • OS: Windows 11 64-bit

  • CPU: AMD Ryzen 7 7800X3D

  • GPU: NVIDIA GeForce RTX 4070 Ti SUPER (latest drivers)

  • RAM: 32 GB DDR5-6000 MHz

  • Storage: 2 TB PCIe Gen4 NVMe SSD

  • Display: 240 Hz monitor

Other games and older Bedrock builds perform normally.

Likely memory leak or rendering engine regression introduced in the latest patch.
