AMD ha lanzado hoy una nueva versión de sus controladores gráficos Catalyst, concretamente una versión RC (Release Candidate) de los Catalyst 14.4 que indican una maduración tras la versión beta que hará que durante las próximas semanas llegue la versión con el certificado WHQL.


Los AMD Catalyst 14.4 RC traen pleno soporte a la API OpenGL 4.4, y mejoras para equipos basados en configuraciones CrossFire además de mejoras de rendimiento en Battlefield 4 (y solucionar bugs)bajo la API Mantle. Estos controladores gráficos también llegan para dar soporte a la AMD Radeon R9 295X, a toda la serie gráfica Radeon R9 200, y a unas ya maduras AMD Radeon HD 5000, 6000, 7000 y 8000 Series.
