About thet mods i skip companions/skins and so.
(im using 255 mods + the texture/body/sounds that dont use esp, so probably 300+ mods, 33gb skyrim).

Here are examples of how the game looks like with diferent settings:

Vanilla:

Vanilla + climates 3.0:

Climates 3.0 + ENB:

ENB + Textures + Climates 3.0:

ENB + Textures + Climates 3.1:

Whit all installed. After this point you can play with your brightness:


After installing all of the things i used this tool to save memory. I optimized textures and BSA only.
I rarely have a CTD and my save game is probably full of sht since i tested many stuff without starting new game (15mb each save).

To avoid CTD i did this steps.
1 Order mod with BOSS and then NMM if needed.
2 Tes5edit to check for errors. Then:
- Apply filter for cleaning
- Undelete and disable references (in all mods with errors)
- Remove identical to master records (in all mods with errors)
3 Open Wrye bash and start BOSS with it. Then rebuild patch.
4 Order mods with NMM again if needed.

If the game freeze (also very rare) is because:
-running around and game simply freeze. I fix that by going other way and coming later.
-entering a cave/inn. I fix it by renaming texture folder to any name, load game, enter the cave/inn, save, rename back the texture folder and continue playing.

Plz suggestions and comments are greatly appreciated.
