Even when I switch back to real vision, my performance drops. It was as if I was still running the enb, just without the effects. When I disabled the enb through the in game menu, my performance literally did not change. For instance, I could be running the game at 62 fps and then when I move to another area, the frames drop to 25 and then back up, but this time it'll only go up to 40. I went from 70-90 frames to 40-60, and allot of stuttering. Ever-since then my performance has been terrible, I even got it to work with the wrapper version, but my performance was still bad. But for some reason the game wouldn't work with the wrapper version of the enb, so I had to use to injector. One day I decided to try out a new enb (Natural Lighting and Atmospherics for ENB).
I ended up adding a bunch more mods but I don't think I added any other mods for a while, except for some game play and armor mods. That was with Real Vision ENB, 2k textures, and some grass mods to increase density. I used to run the game at an average of 70-90 frames outdoors and 100+ indoors. So, I have an i7 4770k, 16 gigs of ram and a GTX 780.
