Total Mods? Probably just every single file I ever downloaded. The only things you should pay attention to is the ' Active Plugins'. Total Plugins: 379 | Active Plugins: 246 | Total Mods: 2571 | Installed Mods: 742 | Active Mods: 623 If you use NMM, there is a way to watch yourself of your mod limit. That's more or less the impression I got, so I think you're right. I'm not 100% sure though so I could be wrong. Once you exceed that limit, I think Fallout will start experiencing memory problems which doesn't necessarily mean you can't play the game, but that crashes when entering or leaving a building for example, becomes more frequent. You could have as many as 500 texture mods if you so wished, provided your computer could handle it. When people say mod limit, it's the limit in terms of esp's and esm's.
