ATI is boasting with the H.264 video support of its upcoming R520 card and NVIDIA obviously can't stay behind. The Inq today reported NVIDIA is planning to launch support for H.264 with its upcoming ForceWare 80 drivers.
We saw some documents where Nvidia claimed that its cards will be able to offload a lot of work from the CPU, while playing WMV-HD content. Please bare in mind that this standard defers from the original H.264 High Definition (HD) codec and specification. Nvidia claims that will have some kind of acceleration but we believe at least for the start it will be for 7800 GTX only. We expect more information about this soon.
