D-fix [Dragon Nest-Fix]

You can download the file here, or nightly release here.

The main issue in Dragon Nest

The game has a particle bug on the AMD CPU after the 64-bit release. This fork fixes it. Additionally, removing unnecessary computation on low graphics.

Why use this

.pak needs to be updated when dnshader changes (dnshaders2.dat). The dll checks if the specific shader is still the same hash. So updating the dll will be "rarely."

How to use

Download the latest release, then extract the file (d3d11.dll) at the game folder.

└── Dragon Nest Folder
    ├── d3d11.dll
    └── dragonnest_x64.exe

List of Fixes

Mid/High:

• Particle fix for AMD CPUs
• Simplified Grass¹
• No VolumeFog and RadialBlur
• Simplified Volume Tex with little differences on color²
• Fixed shadow³
• Reduce shadow computation on spherical map shader⁴

Low:

• Particle fix for AMD CPUs
• Simplified Volume Tex with little differences on color²
• Simplified ground
• Simplified default
• Simplified Spherical map shader

Note

Simplified in this context is hopefully less instruction count/ISA and GPU usage⁵. This should fix the stupidly high GPU usage on (Volume Tex) FRDN S2 Blue-Green Circle Mech (low FPS), Wind Mech in S3 (will cause stuttering) and others. I only follow SEA's changes, so if you're on another server, some shader might not work for you (.log file).

1. Reduced shadow resolution. ↩

2. e.g. ML tornado. ↩ ↩²

3. Fixed shadow holes. ↩

4. Biggest shader in the game and doing 2x shadow computation for no reason. ↩

5. Removed (some) shadow on low graphics. ↩
