In this update a few things were tweaked to hopefully reduce the load times in the game and updates to the tools which may or may not improve general performance.
- UE4 4.25.3->4.25.4
- C++ compiler updated to the latest stable release
- Removed unused materials (A grand total of 50 core materials are used)
- Merged materials where possible (reduces shader permutation)
- Tweaked some mesh sizes to reduce memory usage
- Level One memory usage improved
- Shader caching optimizations (more specifically asynchronous compiling)
