So here is the ugly default look
Here is the optimised .ini tweaking I spent hour's on.
So I then started working on getting enb in mass effect since it was available for Mass Effect 3 but I never got it working right then I found I could use the FXAA Post Process Injector from Skyrim Nexus and messed with the settings to get sharper textures, more saturation, some bloom and it provides better antialiasing than using the graphics card control panel. I also used Ambient Occlusion which actually works in the game.
Shadows still suck but nothing can be done about them.
