It has been confirmed that AoC is a piece of ****. It's an 8 year old proprietary 'rebuilt' engine, what do you expect?
The DreamWorld graphics engine was developed by Funcom circa 2000. Other computer games powered by DreamWorld technology include Anarchy Online and its various expansion packs. When Funcom began developing Age of Conan: Hyborian Adventures, the company reviewed its existing technology base and decided to focus on the further evolution of their proprietary DreamWorld engine as opposed to licensing a third-party engine like many online RPG companies do. As such, Funcom began to retool their engine with the overall design, pipeline and implementation process was taken into account. In light of these changes, the DreamWorld engine has been rebuilt for Age of Conan: Hyborian Adventures with new features, special effects and optimizations.
