Powermizer and Video Playback

Hey guys,

Recently Oceanus just helped get my temperatures stable by helping me enable powermizer on my m15x which for some reason was disabled.

Temperatures are running wonderfully now, but something I'm noticing is that while powermizer will correctly clock my gpu when running things such as LotRO, ATI-Tool, or any other graphic intense program, it doesn't seem to clock it whenever I'm watching HD flash streams like Hulu, causing extremely stuttery playback. Rivatuner shows that it maintains its lowest clock setting during full screen playback. Non-fullscreen works fine, but I'm guessing that's just because it isn't rendering all that much.

Anyone else have this issue?

EDIT: Just noting, I'm able to confirm that the GPU is the issue here, as I can run ATI Tool to set the clock to max temporarily, and the HD streams run fine before it clocks back down to minimum.

 

Ah, I forgot to mention that there was a drawback to having powermizer enabled and I suppose you found what it was. Full-screen video playback (with powermizer enabled) should work fine when your notebook is plugged in and it should normally stutter when it's not.

Does your video playback in full screen stutter while your notebook is plugged in?

 

Just clarifying the status of my issue (since we talked about it off forums), so other's who may have the issue can follow.

Laptop is set to High Performance (Vista), and is on A/C power. Issue occurs with Hulu only, but is able to be slightly fixed by disabling Hardware Acceleration from the Flash options.

Both Oceanus and I are looking for the reason as to why it's only Hulu, but feel it may have to do with the codec they use (since they're offering copyrighted digital media).

 

There are also some inconsistencies between XP and Vista. This issue does not happen in XP (with powermizer enabled and running at the lowest default clock speed), but it does happen in both Vista and Windows 7.

 

Bleh...this is starting to get on my nerves. So, I decide that I was going to give Hulu a rest since it was bugging the mess out of me. I head on over to Netflix which uses the Silverlight player for their instant movies and stuff.



I'm getting numerous downclock "pings" on Silverlight as well. Every 30 seconds or so my video will basically freeze or skip while it downclocks, then it goes back up to maximum.

Powermizer's like a double edge sword. Keeps my card from cooking itself. But keeps me from doing small tasks such as watching fullscreen video.
