I am still getting the purple textures on some objects, mainly armour. My Skyrim is fully patched with High Res pack not installed. I am running only these graphic enhancing mods : FXAA Post Process injector, Realistic Water Textures and Sunglare V3.

Specs:
Processor: 2.5 GHz Intel Core i5
Memory: 4 GB 1333 MHz DDR3
Graphics AMD Radeon HD 6750M 512 MB

I am also running on Windows 7 Bootcamp on a 2011 iMac if this changes anything.
