Oh, great to see vendors experiment more with the Lucid Hydra technology. Double thumbs up!PowerColor Radeon HD 5770 Evolution graphics board with Hydra Engine by Lucid will allow its owners to take advantage of hardware distributed graphics processing technology developed by LucidLogix in multi-GPU configurations. One of the advantages of such approach may be better scalability compared to ATI CrossFireX technology that relies on the so-called AFR approach, which does not scale well in certain cases. Another advantage of Hydra could be ability to boost graphics performance of systems based on older ATI Radeon HD graphics boards or even Nvidia GeForce graphics solution. The aforementioned way to upgrade, however, means that features like DirectX 11 will not work and some games may have issues.
