Use a current build
Install updates from the official Blurred download flow and check the changelog when behaviour changes.
Prefer known-good configs
Start with a ready-made configuration, then change one group of settings at a time. Save a working profile before experimenting.
Keep Windows current
Current Windows updates can affect drivers, permissions and application behaviour. If a problem appears after an OS update, check the relevant compatibility guide.
When performance changes
Close unnecessary background applications, avoid stacking conflicting overlays and test with a clean configuration before changing multiple variables at once.
