A cumbersome bug in the Catalyst 7.12

The latest Catalyst version is the 7.12 (the Cat7.12 internal number is 8.442.0.0). But exactly like the Cat7.11, these drivers have a bug in the management of dynamic lights in GLSL. But this time, I searhed for the source of bug because this bug is a little bit cumbersome in Demoniak3D demos. And we can’t […]

Les Catalyst 7.12 toujours à la sauce “Bug-Inside”

Les derniers pilotes Catalyst ont la version 7.12 (le numéro interne des Cat7.12 est le 8.442.0.0 – c’est pas un téléphone ok!). Mais exactement comme les 7.11, ces drivers ont un bug dans la gestion des lumières dynamiques en GLSL. Mais cette fois-ci, je me suis mis à la recherche du bug car il est […]

Les nouveaux Catalyst 7.11 à la sauce “Bug-Inside”

ATI vient de nous livrer les nouveaux Catalyst 7.11 pour nos belles Radeon. Mais on dirait que ça commence à être une habitude chez les petits gars d’ATI de nous pondre des pilotes bogués surtout pour les nouvelles cartes! Souvenez-vous des Catalyst 7.9 qui enfin corrigeaient un gros bug au niveau des shadow-maps et ce […]

Catalyst 7.9, Radeon 2900 and Surface Deformer

From oZone3D.Net Forums, the Catalyst 7.9 seems to unleash ATI Radeon 2900 GPU. The Surface Deformer benchmark is a benchmark that requires a lot of vertex processing horse power. With Catalyst prior to 7.9, the score of an ATI 2900 was around 8000 o3Marks (that was already high). Now with Catalyst 7.9, the 2900 gets […]

Catalyst 7.9 and Radeon 2K Shadow Mapping Bug

I found this bug while I was coding a new small soft shadows demo for GPU Caps Viewer. Soft shadows are built on shadow mapping and my OpenGL shadow mapping code works perfectly on all Geforce 6/7/8 and Radeon 1k but not on Radeon 2K (2400/2600/2900). Why ? Because of the shadow mapping comparison function […]
