Quick answer
Establish a repeatable test before changing settings. Update the game and driver, restart, observe one scene, change one option, and compare the same scene again. This separates persistent performance limits from one-time loading or background activity.
Reversible troubleshooting order
- Confirm version 1.03 and restart after updating.
- Close capture software and nonessential overlays.
- Restore default graphics, then test a stable frame cap if available.
- Reduce the most expensive visual setting one step at a time.
- Compare CPU, GPU, and memory pressure with the official requirement tiers.
- Verify files only after preserving any local progress you cannot replace.
Version 1.03 says the physics engine frame rate was increased. That describes an internal change, not a promise that every supported PC now reaches a specific target.
The third-party troubleshooting page offers general diagnostic ideas, not measured Iron Blight benchmarks. This article therefore avoids a claimed “best settings” preset, exact frame-rate uplift, or hardware result that has not been independently reproduced.
