Started talking to my AMD developer relations guy again - waiting on them for feedback about how to best approach this (either to correct it engine side or to try talking nicely to the driver). |

To my knowledge, the simple act of renaming the Doom 3 executable resolves problems with Catalyst AI as the profiler does not know to assign the erroneous optimizations to the new executable. If you allow the new TDM build to be renamed to DarkAthena.exe you will resolve the artifacts and allow the mod to run in crossfire mode. That said, ATI's driver's are very sensitive to ARB code order issues. If you switched to one of the GLSL forks you could let the Driver chose the ARB assembly rather than trial and error... Raynorpat's GLSL with StencilOpSeparate for the Carmack Reverse: http://git.iodoom.org/~raynorpat/iodoom3/raynorpats-glsl_iodoom3 LogicalError's GLSL with enhanced Speculars: https://github.com/LogicalError/doom3.gpl Plus you would gain the performance optimizations for GLSL rather than hoping that your ARB code order is mapped well to the hardware... |

Renaming the exe : no Using GLSL : not within my level of care or scope of this ticket Resolving this with the least changes, using the correct method: yes. |

To clarify... Version 1.08 wont ship as "darkmod.exe" or "thedarkmod.exe" but instead it will be shipped as "Doom3.exe" ? Or are you claiming that renaming the executable no longer resolves these problems? Or are you saying that end-users wont be allowed to rename "darkmod.exe" to "darkathena.exe" for some reason (hard coded executable reference)? Once more ambitious engine changes are adopted, utilizing the Doom 3 profile in Catalyst AI will be pointless anyway wont it? If anything, the Brink and RAGE profiles suck too... you'd want to use the Chronicles of Riddick Dark Athena profile for anything modern in OpenGL until some big studio releases another (better supported) title... And maybe emulate some of their render methods... Though it would be cool if ATI Dev-Rel would look at the post-process shader and offer an alternate method. (Mostly for historical purposes. The "upside-down" issue has plagued Doom 3 Bloom mods for ages... it would be cool to see why.) |

The engine that ships with TDM will be called TheDarkMod.exe. |

1) ATI is now AMD 2) Catalyst AI doesn't really exist anymore 3) Recent AMD drivers don't really cause this problem anymore 4) TDM ships as TheDarkMod.exe 5) 2.06 has a GLSL render backend |
