Just one question I didn't see anywhere answered: is it a DirectX-bound modification (like ENB for DX9)?
On *my* rig the "DX10 Preview" gives me 10 - 20 additional FPS and since I prefer to fly in FTX areas I need all FPS I get. That's why I never considered using ENB and DX9. That was probably the biggest setback of DX10. If your modification can alter colour ramps independent from DirectX it would be great news for me.
