GTR2 Antialiasing and Diablo III AA Mode

Overview

tl;dr

• 0x004412C1 (Diablo III) Antialiasing Compatibility:
  • Required to make Override AA work when Fullscreen Anti-Aliasing is Disabled in GTR2Config.exe
  • 0x00000000 (Default) is sufficient when Fullscreen Anti-Aliasing is enabled in GTR2Config.exe

AA Override vs Enhance:

• AA Mode Override always works
• AA Mode Enhance only works when AA is at least enabled in GTR2Config.exe
• AA Mode does not seem to be related to Fullscreen vs Windowed mode

  - No special AA Compat needed when Fullscreen Anti-Aliasing is enabled in GTR2Config.exe
  - Fullscreen vs Windowed doesn't seem to matter
  - So, might as well leave Diable III AA Compat enabled at all times.
