Basically the issue here is that my FPS swings massively going from exterior to interior environments. This wouldn't be strange if it weren't for such huge differences in FPS.

All I want to know is how realistically possible it is for my FPS to go from 5-10 in exterior environments (cities and the outside world) to 45-60 in interior environments (caves, dungeons, even heavily demanding areas like the Moss Mother Cavern). If it were a smaller jump I wouldn't be shocked.

The main mods that I have installed that really seem to affect my FPS are:

- Realistic Lighting
- Skyrim HD 2k Textures
- and Sharpshooters Extreme Graphics Vision ENB - Good performance version.

Other than that my mods, which I enabled one at a time did not seem to make a difference to the FPS.

If you want any more details, such as my computers details or full mod list, just ask, but I need to establish if this is normal behaviour first.

Edit: I forgot to mention that I use the FPS Booster v1.1 which seems to help a lot with interior fps, but not exterior. I'm thinking that this could be the issue.

Thanks!
