Issues fixed

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

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

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

    The RTX crash is fixed by this patch while also not modifying the mtndew.dll file, allowing players to still be fully updated - and fix all known issues of the previous release.
