Processor: Core Duo (Higher Recommend) (AMD some similair to intel)
RAM: 2 GB (3 GB+ Recommend)
Limitations: No Directx 10 on FSX
What it does: It creates a very good bloom effect (you dont have to enable Bloom in FSX!!!!!!)
And shadows on objects (Cars, Houses, user aircraft).
More realistic look in FSX/FS9, so darker ground a brighter sky.
And also HDR (High Dynamic Range)
