*.geomx
About
*.geomx files contain geometry buffer data that serves as an alternative to the standard *.geom format. The engine loads these files during level initialization as part of a two-stage geometry loading process:
- First, it loads the standard 
level.geomfile containing vertex buffers (VB), index buffers (IB), and sliding window items (SWI) - Then it loads the 
level.geomxfile as alternate/fast geometry data
