Geforce FX 5900 Ultra - NV36 supports pixel shader 3.0
Some of Nvidia guys that know how things work have told our friends that NV36, Geforce FX 5900 Ultra already has support for pixel shader 3.0 but there is no any driver publicly available that will support it. µ The same source implied that when Nvidia tested pixel shader 3.0 internally, there was a hardware problem.
