The Inquirer today claims NVIDIA has a secret video driver that may give ATI's Avivo a run for its money. This driver will be released soon and is supposed to beat ATI's cards in video performance.
This driver will ensure that NVIDIA's 6150 integrated graphics chipset and the low-end GeForce 6200 will be able to play H.264 high-definition content at a 720P resolution. Faster cards should be able to play 1080P without a problem.
The new driver will allow all Geforce 6 and 7 series to play H.264 content. Yes, this means each and every card from Geforce 6200 to 7800 GTX will play H.264. I still wonder about NV40 based cards as they had some troubles with WMV files before. ATI R5XX generation can play H.264 but not the older R420/430/480 generations. None of these cards are actually supported for H.264 playback and we don’t think ATI will provide any kind of H.264 support for those older cards. Kind of bad for you if you have one.
