Fix a Problem / improve frame rate and stability on PC

PC Performance Settings: A Safe Tuning Order

Quick answer

Start with the official target, not an all-Ultra preset: use 1080p, enable the supported upscaler, select Performance mode if your hardware is near the published tier, and cap the frame rate to a value your PC can hold. Then lower one expensive visual setting at a time while replaying the same scene. Keep the SSD requirement, 16 GB RAM baseline, power mode, driver version, and background apps in mind before editing configuration files. Back up any file before changing it, avoid copied launch options with no source, and reverse the last change if stability gets worse.

Baseline before changing settings

  1. Record CPU, GPU, RAM, driver, resolution, and game version.
  2. Confirm the game is installed on an SSD.
  3. Close overlays and background capture tools for one comparison run.
  4. Choose a repeatable scene and record average behavior, not one brief spike.

The minimum note targets Low 1080p at 40 fps and the recommended note targets Medium 1080p at 60 fps. Both mention Performance upscaling. If your hardware is close to a listed tier, expecting native 4K or maximum settings is outside the official promise.

Stutter versus low average frame rate

Low average performance responds to resolution, upscaling, frame caps, and visual settings. Intermittent stutter can instead involve shader compilation, background tasks, storage, or a specific game build. Do not treat one remedy as proof of a universal cause.

Configuration-file warning

Launch-week community posts may recommend direct edits. Back up the original file, change one line at a time, and keep a written rollback. Do not download replacement configuration files or executables from an unknown source.

When to stop tuning

If the game crashes more often, produces visual corruption, or no longer starts, restore the last known-good setting. Report a reproducible issue with hardware, driver, game version, and steps rather than only “bad performance.”
