Issues fixed[edit]

The best way to report game issues to the ElDewrito community and get assistance, is via the mod's latest bug report thread.

Crash on Nvidia RTX chipsets[edit]

The game has a bug whereby Contrails cause the game to crash, notably on RTX GPUs.[4]
Replace binkw32.dll with this version
  1. Download the Unofficial Mod Patch which fixes the RTX GPU crashes when the game uses contrails.
  2. Navigate to <path-to-game> and replace the binkw32.dll with this one.

Notes

Tested on a Nvidia GeForce RTX 2080ti on Windows 10 build 1809 [5]
If the player has used the previous version of this fix, they must also download the original mtndew.dll file - which is also included in the link - and replace the modified mtndew.dll with the original one.

Game is too bright on Intel HD Graphics[edit]

Enable the Bloom (Brightness) Patch in the game's Advanced Video settings, and restart the game.
