A aby nebylo pochyb, tak info od majitele 7800.

Well, I can confirm the H.264 support is working somewhat. With the 77.72's trailers & music videos from Apple's HD Gallery would run extremely chopping pegged @ 100% cpu utilization. With these drivers, the cpu utilization now flucuates between 60% - 90% normally staying at 75% which makes the playback much better. Once the 80.xx series matures, it'll be perfect.

WMVHD cpu utilization is between 45% - 50% w/o Purevideo installed.
