Witcher Engine Fix 0.6.3

Witcher Engine Fix 0.6.3 adds an extreme level to the longer draw distances, for fast PCs.

• Extreme ([graphics] detail=3 in System\witcher_enginefix.ini, or Ctrl+F12 in game, which now cycles off, high, ultra and extreme):
  • shadows out to 180 m (the game: 30 m, ultra: 90 m);
  • distant lights stay on 10x farther;
  • scenery keeps full detail 10x farther: ground, buildings, fences, and the trees and bushes placed in the Outskirts and similar areas. It uses the same protection against holes as high and ultra.
  • creatures and trees 4x farther;
  • grass 3x the slider's range;
  • decals 200 m and weapon effects 120 m.
• Compared with the Higher LOD mod: extreme comes close to its ranges, without its debug mode, map reveal or holes, and on top of what your options menu sets. Grass density is left alone, because the engine never reads that setting. Do not use the two together: Engine Fix would multiply Higher LOD's values again.
• Cost: on my PC (4K, everything at maximum, capped at 72 FPS) extreme held 72 FPS in the Outskirts. The engine does nearly everything on one CPU thread, so older PCs may lose more. High and ultra are unchanged.

Upgrading from 0.6.x: extract the System and Data folders from WitcherEngineFix-0.6.3.zip into your game folder and allow overwriting. Your witcher_enginefix.ini is overwritten too, so reapply any changes you made to it. After starting the game, System\witcher_enginefix.log should show enginefix 0.6.3 loaded.

Requirements: The Witcher: Enhanced Edition, patch 1.5. Tested on Steam 1.5.0.1304 (Windows 11, DXVK).
