EasyOptimizer-V

A high-performance GTA V texture optimizer written in pure C with Win32 GUI.

Features

  • YTD/WTD/YDR/YFT/YDD support — Load texture dictionaries and extract embedded textures from drawables, fragments, and drawable dictionaries

  • Smart Optimize — Batch resize and recompress textures with configurable max resolution, format, and mipmap settings

  • Fast Recompress — One-click recompression of all loaded textures using the active encoder

  • CPU & GPU Encoding — Toggle between bc7enc (CPU) and NVTT (GPU via nvtt.dll) for BC1/BC3/BC5/BC7 compression

  • Per-Texture Editing — Resize, change format, and set mipmaps for individual textures

  • Duplicate Finder — Find duplicate textures by name or data hash across all loaded files

  • Folder Scanner — Recursively scan directories for all supported file types

  • Drag & Drop — Drop files directly into the window to load them

  • Sorting - Sort loaded archives by name, type, total size, texture count, or modified state

  • Languages - Switch the main interface between 15 languages: English, Portuguese, Spanish, Russian, Turkish, Mandarin Chinese, Hindi, Japanese, Arabic, Bengali, French, German, Indonesian, Korean, and Italian

Saving

Save All creates a versioned project cache under
projects\project-YYYYMMDD-HHMMSS-mmm\ next to the executable before writing
files. It then offers:

  • Yes - replace original YTD/WTD files
  • No - save copies to another folder
  • Cancel - keep files unchanged

The same popup also offers a cache-only snapshot without replacing files.
YDR/YFT/YDD inputs are read-only models: their extracted textures can be saved
as YTD copies, but the original model files are never overwritten.

Building

Requirements

  • Windows 10+
  • Visual Studio 2019+ (MSVC toolchain with cl.exe)
  • No external dependencies needed — all libraries are vendored

Steps

  1. Open a Developer Command Prompt for Visual Studio (or run vcvars64.bat)
  2. Navigate to this directory
  3. Run:
build.bat

The compiled executable will be at build\EasyOptimizer-V.exe.

Optional: GPU Encoding

Place nvtt.dll (from NVIDIA Texture Tools) next to the executable to enable GPU-accelerated texture compression.
