No Reflection MOD
This is a very simple performance mod that totally deactivates reflections when set to "Low" in your graphics settings.
Reflections look great when set to "High" or even "Medium", but tend to blur the image when set to "Low", while staying quite demanding on some systems. This mod is aimed at people with low-end machines or that need the extra fps.
Extract _MOD_no-reflection in your mod folder, set Reflection to "low" in your graphics settings. Not sure if you need to regenerate the SHADERCACHE, try it to be sure.
