New Features
Added a Pixel Upscale graphics option, available from both the title screen and in-game settings.
Improvements
Greatly reduced GPU shader work underground. Fully opaque fog now prevents hidden world layers from rendering.
Precomputed fog lighting and wall bleed replace expensive per-pixel searches.
Empty lava-ocean regions skip unnecessary terrain and background calculations.
Reduced terrain, lava, mountain, and background shader work on lower effects settings.
Fresh drill cuts now glow more clearly against dark terrain.
Bug Fixes
World rendering now recovers after minimizing, changing fullscreen state, or restoring focus.
Graphics controls no longer accumulate duplicate callbacks when menus rebuild.
Pixel Upscale no longer breaks the game when toggled.
Increasing Brightness no longer exposes terrain hidden beneath fog.
Ore veins are visible again.
