CPU Multicore Optimization Bottleneck

My Hardware Configuration:

  • Laptop CPU:Intel 12th Gen i7 processor
  • GPU: NVIDIA GeForce RTX 30 series Laptop GPU
  • RAM: 16GB DDR5
Detailed Issue Description:
To isolate the issue, I set all in-game video settings to their absolute lowest values (Lowest preset, Low Effects).
Despite this, my GPU usage remains unexpectedly low (70-80%), leading to suboptimal framerates. This confirms a severe CPU-bound scenario where the GPU is idle while waiting for processing from the CPU, completely independent of graphical load.

The core issue appears to be inefficient multicore utilization:

  • All CPU Performance Cores (P-Cores) maintain a high clock speed (~4.08 GHz)
  • Overall CPU utilization remains surprisingly low (20-30%)
  • Per-core monitoring shows severe thread imbalance with 1-2 cores heavily loaded while others remain largely idle
This creates a classic single-thread bottleneck where the game's main thread saturation prevents the GPU from reaching its full rendering potential, despite abundant CPU resources being available.

Why This Matters:
Modern gaming hardware, particularly Intel's 12th+ Gen hybrid architecture CPUs, requires sophisticated thread distribution to achieve optimal performance. The persistence of this bottleneck even at minimum settings clearly indicates that the limitation is computational (CPU threading), not graphical.
