I found that, with all of my current graphics mods, adding RealVision on top of it all is a little too much for my computer to handle. I've tried uninstalling it countless times but each time I reload my save game, the game crashes.

I followed the instructions on the RealVision ENB page precisely. I'm using MO, so I went to Mod Organizer/mods/RealVision ENB/RealVision_ENB_Files and launched RV_launcher.exe. I uninstalled it then deleted every ENB related file in my Skyrim directory. The final step (which I was kind of skeptical about) was to delete both the skyrim.ini and the skyrimprefs.ini from the Mod Organizer profile's directory. This should have been it, right? I even tried leaving the ini files at one point and it still crashed.
