昨天去Wiki爬了下文,发现关于第三代PureVideo HD(VP3)的介绍如下:
The Third Generation PureVideo HD
This implementation of PureVideo HD, VP3 added entropy hardware to offload VC-1 bitstream decoding with the G98 GPU (sold as GeForce 8400GS), as well as additional minor enhancements for the MPEG-2 decoding block. The functionality of the H.264-decoding pipeline was left unchanged. In essence, VP3 offers complete hardware-decoding for all 3 video codecs of the Bluray-Disc format: MPEG-2, VC-1, and H264.
All current third generation PureVideo hardware (G98, MCP77, MCP78, MCP79, MCP7A) cannot decode H.264 for the following horizontal resolutions: 769-784, 849-864, 929-944, 1009-1024, 1793-1808, 1873-1888, 1953-1968 and 2033-2048 pixel.
The third generation PureVideo HD is sometimes called "PureVideo HD 3" or VP3, although this is not an official NVIDIA designation.

啧,没想到VP3居然有这么脑残的限制(见红字部分)。出于兴趣,用着VP3显卡的朋友麻烦帮忙试验下是否如此~ |
