GEM FX

UPDATE 1.1.4:
It is recommended to use MSAA as AA option, since this is the only way that GEM FX can still retrieve information to calculate lightning effects properly.

This mod attempts to enrich the in-game atmosphere by adding new and changing existing effects in the X4 effect pipeline, such as

• improved FXAA
  
• new lens effects
  
• improved light effects
  
• cinematic effects
  
• texture filters (currently removed based on user feedback)
  
• LUT framework to allow creation and sharing of Color Correction modes

Since the mod does not require any third party tools

• gemfx has near to no impact on performance due to having no overhead
  
• gemfx effects are not applied to the UI due to being part of the existing pipeline
  
• gemfx can be considered safe to use due to not running any external binaries
  
• gemfx allows toggle effect options through in-game menu
