Netflix is all software, and not bandwidth-intensive. It does not use H.264, and due to MS support issues, mainly that GPU offloading wasn't enabled for Silverlight, uses the CPU for rendering. Your CPU has plenty of performance for Netflix HD, though.

It's very much a Silverlight/browser/driver problem, but I'm not sure what causes it (it mysteriously went away on the laptop I use for the TV, after awhile. New driver? New browser? Netflix fairy liked my cats?). Oh, yeah, one thing you might want to try is a different browser. It shouldn't affect anything, but it wouldn't hurt, either.

Doesn't Netflix use VC-1? Anyways, I returned the 6450, since it wasn't helping anything.

I guess I'll just use my MacBook Pro or Core i7 iMac.

I think I've found the main problem. I didn't know to look for it before, but it turns out AMD's Cool'n'Quiet was enabled by default in the BIOS, so I disabled it. Since then YouTube 1080p has become more consistent. Very smooth the vast majority of the time. Before, sometimes it was smooth but sometimes it wasn't, esp. when it was still buffering. It's good in both in Firefox (regular Flash) and IE (ActiveX Flash), whereas before it seemed worse in Firefox. Netflix HD also shows a significant improvement.

So in summary, it took me half a year and experiments with a new GPU, to figure out the bulk of the problem is a single BIOS setting for the CPU. :eek:

ive always had issues with netflix streaming, even on my Xbox 360 with a wired comcast connection. i think its a router problem. i could never figure it out so cancelled the service...

I'll keep that in mind, should I encounter it, again.

CPU usage up to 65% max. That's according to the built-in Windows 7 CPU/memory usage widget. I can't remember if it decreased when I turned on hardware acceleration, but it may have. I'll have to check.

BTW, for Silverlight I closed the browser and relaunched, and I even tried rebooting after a setting change a couple of times, but no difference.

How do I measure the GPU usage?

Last I checked, Netflix is only hardware accelerated in windows 8 using the app.

You don't need hardware acceleration for HD playback on modern (or even most several year old) desktop CPUs. However, Netflix HD with Silverlight isn't ideal. I'm hoping Netflix with HTML5 will be more consistent.

Old thread, but I just wanted to report that the Netflix app on Windows 10 is perfect. 1080p is buttery smooth. Works great in the Edge browser too.

It's amazing what a proper implementation can do. I haven't tried turning Cool-n-Quiet back on though. I may be using more energy, but the computer remains cool and quiet with my business application type usage, surfing, email, and Netflix.

I think I'll just leave this machine as is. Even if someone were to release an uber cheap fanless low profile GPU with hardware 10-bit HEVC decode support, I don't think I'd bother getting it, since the machine likely won't have the support for Netflix 4K's DRM.
