I'm going to get back into Oblivion, but I want to mod it to be more enjoyable and better looking without a severe reduction in framerate. Here's what mods I have right now:

Get Wet 1.1

Oblivion_Character_Overhaul 2.0

RshAlchemy 1.0

Tamrielic Ingredients

Khajiit Night Eye Toggle

Quest Award Leveling

A mod that adds additional clothing.

Armamentarium Katanas

Alive Waters

Natural Environments

I want Oblivion to look amazing. That is my highest priority. What would you suggest for modding Oblivion?

Why not using Oblivion Character Overhaul 2?

Oh, sorry. I did get OCO v.2. I'll change it. Dang typos.

Sub quest award levelling with http://www.nexusmods.com/oblivion/mods/39635/?

And armamentarium katanas with Armamentarium 1.35

Uh... I already have a quest award leveling mod that does the exact same thing.
