ATI cards: Is your WMV acceleration working?

[rbV5]

I've not had a chance to test it on my rig yet, but I've read posts where WMV acceleration is enabled with the latest ATI Catalyst release (I must have missed it in the release notes) Check out the "Step into Liquid" 1080p demo Here and if you can report back what your CPU utilization is using WMP10. Try it with HT on/off if you can (Intel) and the clockspeed of your processor/ which ATI card you have and whether you dropped frames or not (View>Statistics) anything else of relevance you can think of.

Well, currently both of my HDD's are non-bootable. Woke up 1 morning to find my system not booting but they are fine for transferring/storing data. Both went at the same time.

Abusing my dads PC at the moment so as soon as I get my rig back together (hoping I dont need an RMA even with both HDD's in warranty) I'll check it out for you on my 9800P.

Bump for some results. I am looking at the Pro VIVO and this is a very important topic to me.

I didn't run the step into liquid test, but the acceleration does appear to be working for me. When I was troubleshooting my DVD playback issues, I noted that my CPU usage went from ~45% to ~20% when trying to play a DVD movie.

Interesting, but irrelevant.

DVDs use MPEG2; what they're asking about here is WMV. Totally different formats.

my CPU usage is about 40-80% on the step into liquid test. i'll try it later w/o WMV acceleration enabled to see the difference.

OK, I had to uninstall CCC to use the legacy CP to find the WMV Accelerataion checkbox on the Options tab of the advanced display properties (I coudn't find the checkbox in CCC, its likely enabled by default as it was when I checked it after uninstalling CCC)

I ran the demo several times with WMV Acceleration checked, and unchecked both in WMP10 and ATI file player, both using overlay and VMR9 renderers. I see no difference either way in both PQ, or CPU use. It runs fluid, but CPU use peaks ~90%. Any other use of the PC will peg it at 100% and drop frames.

It appears to me that the checkbox has no effect, and that I'm getting my normal results unfortunately.

Which ATI cards have the WMV accel. feature on hardware... just R4xx ?

Should be R3xx forward.

I'm using Catalyst 4.9's, a Radeon 9800 Pro and a P4 2.8C @ 3.1 Ghz with HT on.

Playing the Step Into Liquid 1080p trailer my CPU usage fluctuates from 40-60%; it's mostly below 50%. At the end I get 0 frames skipped reported.

I just rebooted and ran it again with HT off. 0 frames skipped again, but CPU usage was MUCH higher - 80-99%, about 82% on average.


So, I'm not sure if this is due to WMV acceleration, HT or both.

Is there a option for this somewhere in CCC? 'Cause I've got a R3xx card but haven't seen anything about WMV accel. in my CCC

I couldn't find it either, I think its just enabled by default, so with CCC you can't turn "it" off (whatever "it" is since I'm really not seeing any difference betweeen checked and unchecked) unless I missed where it was located in CCC.

Similar pre-WMV Acceleration experience here as mentioned in other threads (your difference is all in the HT, and Overlay Mixer offers far higher performance than VMR7/9 without HT but equivalent with HT).

My WMV Acceleration testing experience copied from rage3d:

Okay I installed the crappy player and ran Step Into Liquid trailer another hundred friggin' times and I am fairly confident that there is no net acceleration however I did discover something curious... CPU usage is roughly around 50% with my "P2.9" HT but when WMV Acceleration is enabled (may require forcing refresh through CP betwixt toggles), instead of each logical processor's usage tracking about the same, the first one is around 25% while the second is around 60%. Combining the two graphs still shows around 50%. You might think 25% less on one and 10% more on the other would show a net performance gain of 15% but it doesn't really look like it, although I ran all the tests with Task Manger at a size where the graphs on the Performance tab were only 5 blocks high so these are all rough estimates. If anyone cares to do more detailed testing follow up with your results. I have not tried testing with HT disabled yet.
