|You can hardly see any game that has support for Pixel shader 2.0 and its fancy stuff. Even the first hardware that was capable of handling it, the Radeon 9700 PRO, R300 was introduced more than a year ago now.
Some of Nvidia guys that know how things work have told our friends that NV35, 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.
We reckon that Nvidia is practising for NV40 and who knows, if it fixes things NV38 could end up with pixel shader 3.0 support, highly unlikely but still possible.
