NVidia, ça pue énormément

Suite concernant les différences de performances entre les cartes NVidia et ATi sous DirectX 9, les tchèques de BonusWeb ont eu la bonne idée de poser la question à John Carmack. La réponse est sans appel et contribue à enfoncer NVidia encore un peu plus dans la merde :

Unfortunately, it will probably be representative of most DX9 games. Doom has a custom back end that uses the lower precisions on the GF-FX, but when you run it with standard fragment programs just like ATI, it is a lot slower. The precision doesn't really matter to Doom, but that won't be a reasonable option in future games designed around DX9 level hardware as a minimum spec.
