Ok, thanks for the heads up Bealdwine. Very new to the forums (within the past week or so), decided to become a part of the community to try to help out seeing as there was no direct line to TC himself, and I wanted to try to help other users.
One thing I'd like to mention is I've been looking for a workaround for alternate d3d9.dll files for laptops running Nvidia OPTIMUS, and one thing I found that actually worked is by getting a hex editor, going into the TESV.exe file, finding d3d9.dll and rename to something such as d3fx.dll, then renaming the alternate d3d9.dll file to d3fx.dll. It would load the d3fx.dll file, and use the Nvidia powered GPU instead of the intel GPU. (This solution was NOT originally found by me. I found this by someone else on another forum months back. I'm sorry I cannot give you credit, if someone knows who I'm talking about please let me know so I can give him credit)
Problem with this is that for some reason, when you rename the d3d9.dll from injectSMAA by Andrej Dudenhefner, the d3d9.dll file no longer works. The game loads, it uses the alternate file ON the Nvidia GPU, but the AA doesn't load for some reason. I've tried to get a hold of Andrej, but to no avail atm.
But if you have a normal computer WITHOUT OPTIMUS, then all you have to do is drop the d3d9.dll file from injectSMAA into your TESV.exe folder and the AA looks great. I haven't tried with ENB yet. (I reformat my computer every few months because of how slow windows gets. Keep all the data on seperate HDD and just re-install. So I haven't had Skyrim installed for a while. Works out I guess since the next STEP will probably have everyone re-install from scratch anyways.)
