Ive noticed that if i carry a lot of items, there is a noticeable lag delay when opening containers or the inventory screen. Are there any mods that fixes this?

You should post this in the mod section

This lag may be caused by:
1. Darn UI mod active and it's "folding" categories option installed
2. A lot of items in those categories

Not using darn UI, but i am using the wz inventory mod (morrowind grid style).

As far as I'm aware there is no solution. The more items you display in grid mode, the laggier wz's mod gets. That's just kind of the way it is with wz's mod. I don't know of anyone who has come up with a fix for it.

Try using Darnified instead, it includes a grid-style inventory as well.

Where you can play Tetris with your stuff to make them fit, just like in dear old Deus. Oh, how fun it was trying to make room for both the GEP gun AND the flamethrower!

Just reading the words "GEP gun" and "Flamethrower" in the same sentence gives me a headache. Me, I loved my Sniper rifle and refused to drop it for anything or anybody. Towards the end of the game I think I spent more time trying to rearrange my stuff around that sniper rifle than I did actually playing the game.

Happy times!

I tried using darn ui but the font size is too small, i have to squint to read it.
