Hey guys so i was wondering if there was a way i could deactivate all inactive mods so i can see if it improves performance because i have like 30-60 inactive mods lol

I'm sure that having inactive mods does nothing to performance. They are not active, so your computer and by extension the engine does not have to load them, or read the instructions on those files. They're just wasting space on your hard drive. Removing them will make no difference on how the game is currently running.

If you have FOMM, you can multi-select all the esps you don't want and you can delete them. Multi-select works with ctrl+left click.

If you use FOMM or NMM, just un-check the .esp of the mod to deactivated. Inactive mods won't do anything to damage performance so you're fine. Just un-install the mod to be sure.
