Radeon HD 6755G2 Game Requirement Analysis
Radeon HD 6755G2 can be a combination of a fast-middle-class level Radeon HD 6750M with an integrated Radeon HD 6520G or an integrated 6620G.
This combination is known as AMD Dual Graphics or asymmetric CrossFire. It uses Alternate Frame Rendering (AFR) to render different frames on the two graphic cores and can suffer from micro-Stuttering.
The performance relies on solid driver support and, at times, it might even be worse than a single Radeon HD 6750M by itself. Only DX10 & DX11 modes are supported which means a game set with lower settings and not set to use DX10/DX11 is not accelerated (does not make use of the asymmetric crossfire feature within the card).
Due to the micro stuttering and performance problems, Dual Graphics may sometimes cause more problems than the possible dual card performance gains they suggest.
