Cartes graphiques

Les nouveaux drivers AMD Catalyst 8.12 sont disponibles

Comme chaque mois AMD vient de publier de nouveaux drivers vidéo à destination de ses cartes graphiques Radeon.

Estampillés 8.12 (12 pour le mois de décembre) ils sont disponibles pour Windows Vista, Windows XP et Linux.

Hormis l’amélioration des performances sous plusieurs applications (voir détails en fin d’article) une nouveauté fait son apparition, l’ATI Stream. Il s’agit d’une technologie concurrente à CUDA de Nvidia. La puissance du processeur graphique peut être utilisée à d’autres fins que la 3D. Comme exemple  l’Avivo Video Converter  est proposé ainsi que le client Folding@Home.

Bizarrement l’Avivo Video Converter  est limité aux possesseurs d’HD4800 et d’HD4600 tandis que Folding@Home s’adresse aux Radeon serie 2000, 3000 et 4000.

  1. Les drivers désactive une de mes 2 cartes graphiques rendant par le fait impossible la technologie Crossfire 🙁
