So, with the new 10.1 version of flash player is meant to use your video card to help render video so that it's actually possible to watch videos of a high quality online and such.
Only problem is, it doesn't appear to be doing this at all on my x1950 pro. Now i thought that this card had accelerated video playback?
Anyway, at 480p, small size the cpu usage is 50% and at full screen goes all the way up to 100%.
Now, this actually seems worse that it was in the previous version of flash player? I don't remember a single video causing such cpu usage before?
Could this be due to them switching from directshow to direct3d, and that without graphics hardware support, direct3d for rendering video is alot more intensive on cpu than directshow?

Nobody then?

Probably a daft question but have you checked that the hardware acceleration checkbox is ticked in the Flash player? (Right click / settings - should be on first tab)

Yes, it's checked. I found that it only supports uvd 2 and up supported cards. However I don't really get why that is as x1000 series can accelerate h264 video, which basically all flash video is.
My main problem is it seems that without a supported card, the cpu usage skyrockets compared to what it previously was and i don't really understand why. At least i swear it wasn't that bad before i redid this computer.

You're basically wrong. Only F4V video is H.264. FLV is still quite common, and almost always uses the On2 VP6 codec.

Ok, to be more precise, the majority of high resolution flash video is f4v. Also, flv supports h.264 anyway.

It's strongly discouraged. Adobe Media Encoder doesn't even offer H.264 as an available codec when exporting to FLV.
