Could be that it just was given to little ram? I know the ram has huge difference on the performance off the HD3200 if it doesn't have enough. I had some games that didn't go all that smooth whit 128-384Mb. Had to allocate all 640Mb and lots off things started to click into place.
Many things today are design to need at least 512Mb graphics ram.
512mb of system RAM was allocated for the video.
The 9500GT also has 512mb of dedicated RAM on the card.
Both the system RAM and the memory on the video card are DDR2.
The difference in watching Hulu and Amazon streaming between the on-board 3200 chip and the 9500 isn't huge
but it is noticeable. Not a lot, but enough to smooth out the playback and eliminate the visible frame skipping. (which was very noticeable on my 50" screen at 720p with the 3200 chipset).
Now the 3200 had no problems at all playing back MKV files in 720p and 1080p with media player and Netflix streaming through Silverlight looked fine as well. Only media streamed using the adobe flash player seems to have shown an improvement in using the Nvidia card over the ATI chip.
Now this may be an issue with the chipset or simply a poor implementation in the ATI drivers for Windows 7. Since I haven't tried running any other OS on my HTPC I really can't say. All I do know is that I tried the following ATI drivers for Win7:
And of all of them I saw the best performance using the 9.3 set. That set gave me roughly 20fps. The worst was 9.5 which looked to be closer to 17-18 fps in Hulu.
The difference in performance using various driver versions seems to confirm that the issue may in fact be rooted somewhere in the software rather than being a hardware problem.
Perhaps the situation will improve as Win 7 moves closer to final release and the ATI drivers for that OS mature but for now, using the 9500gt has solved all of my playback issues and gotten me up and running to the point where an episode of Leverage, streamed in HD from Amazon last night looked to be of the same overall quality as my Uverse HD content.
Which is enough to make my wife happy, so I'm happy.
