Nice posts guys. Lifeshield, have you been able to figure out what it is exactly that chokes the gfx cards using Enb? I mean, I have a 7970 with 3gb of Ram and the enb profiles are still pretty taxing. Of course, this must be balanced with a good skyrim and skyprefs ini file to get good performance. How close are you to releasing your full on enb/fxaa profile? Benign, great post! Kind of demystifies some of the stuff going on in enb!
Part of the reason performance is lower using ENB with AMD/ATI GPU's is that Boris Vorontsov the Creator of ENB doesn't have and hasn't used ATI/AMD GPU's he's always used Nvidia and so ENB is optimized for Nvidia by default (at least for now).
My ENB/ injFX config has been done for a while and I have just been playing the hell out of the game From start to finish to get My config done took about 70 hours to get it how I want it. I haven't decided on whether I am going to release it or not as I made it for Myself, My wife and Our friends as they haven't been happy using others configs.. The Bright side is they are all Now happy lol. I might release it though
I was hoping by posting that info it would help some.. ENB is about 85% about lighting, Lighting and Atmosphere make a huge part in enjoying a game and becoming immersed in it. The rest is the Effects and textures
