CPU and GPU Usage Spike Causing System‑Wide Lag

Description of the Issue:

Battlefield 6 causes extremely high CPU and GPU usage (90–100%) immediately after launching the game, starting from the very first loading screen before reaching the main menu. Windows Task Manager reports Very High CPU and GPU power usage, and the entire operating system becomes sluggish: mouse stutter, browser lag, delayed Win+Shift+S captures, and general UI slowdown.

The issue persists throughout the entire session, including menus and gameplay, even with all graphics settings set to Low. The behavior suggests that the DX12 render loop is ignoring FPS caps and monopolizing GPU scheduling, causing system-wide latency.

The game does not generate standard Frostbite logs in Documents or AppData. Only a Steam GameOverlayRenderer log is created, which shows repeated DXGI/DX12 hook attempts and overlay disable/enable cycles, even though Steam Overlay is disabled. This may indicate a conflict between the engine and injected modules.

Steps to Reproduce:

  1. Launch Battlefield 6 from Steam.
  2. Observe GPU usage during the initial loading screen.
  3. CPU and GPU usage spike to 90–100% and Windows reports “Very High” power usage.
  4. System-wide lag begins (mouse stutter, browser lag, Win+Shift+S delay).
  5. Enter the main menu — issue persists.
  6. Start a match — issue persists throughout gameplay.

Frequency:

100% reproducible.

Platform:

PC (Steam)

System Specs:

– Windows 10

– 2560×1440 @ 300 Hz

– G‑Sync ON

– V‑Sync ON in NVIDIA Control Panel

– V‑Sync OFF in-game

– HDR ON

– FPS cap 297 in RivaTuner

– Steam Overlay disabled

Additional Notes:

– Steam Overlay is disabled, but gameoverlayrenderer64.dll still injects into the process and repeatedly attempts DXGI/DX12 hooks.

– No crash occurs during this issue, so the only available file is a .mdmp crash dump from a previous session.

– No Frostbite logs are generated on this system.

– The behavior is similar to DX12 render loop issues seen in other Frostbite titles at launch (uncapped menus, GPU saturation, system-wide lag).
