✨ Key Features
📊 Pros & Cons
✅ Pros
- Community-approved (555 endorsements) and widely downloaded (17k+), so you know it's solid
- Fixes visual and performance issues in Shivering Isles without changing gameplay
- Recent update (2023) means it's likely compatible with current Oblivion setups
⚠️ Cons
- Only affects trees and shrubs—if you're looking for broader fixes, this won't cover them
- Requires the Shivering Isles DLC, so base-game-only players can't use it
For Oblivion players who love Shivering Isles but notice janky trees or performance hitches. If you're a modder or perfectionist who wants a cleaner world without overhauling the game, this is a no-brainer. Skip if you don't own the DLC or want gameplay changes—this is purely cosmetic/performance.
