G3258 (OC@4.4Ghz) IGP chokes on 1080p Flash

[jrichrds]

CPU usage spikes to almost 100% and there is some stuttering when watching 1080p Flash video with the IGP on my G3258 @ 4.4Ghz. Before I start trying all different Intel Graphics driver versions, is this to be expected with the IGP? I thought it would support hardware acceleration. I'm using the latest driver v15.36.25.64.4280 WHQL from station-drivers.

Does it make a difference with HW acceleration off?

Have you tried playing the same video in chrome with HTML5 player?

Well I'm getting stuttering with iTunes and Vudu when streaming on my PC or playing from the hard drive, in both SD and HDX. This is on a system with an i7-4930k stock and GTX 780 Ti GPU. Even without hardware acceleration by CPU should not have a problem with 1080p video decoding. However, playing movies through Kodi and PowerDVD 15 Ultra on my PC, there is no stuttering. That tells my that my hardware is not the issue with the stuttering in iTunes and Vudu.

The latest version is 15.x.4285 ~

Also you could try & overclock the IGP, I've got mine at 1500Mhz, & see if that solves anything btw that behavior is very odd especially since hw acceleration should work reasonably well with the latest flash versions.

Would he need to adjust his Long and Short Power Limit setting in BIOS? Do they limit the IGP power / performance when the CPU is overclocked?

I remember the days I could play a HQ 12GB 1080p video on a slightly overclocked AthlonXP2400+. Ok it was the only one I had and I was watching it on a 1024x768 resolution (which would have required extra downsizing calculations) but it played smoothly, if there wasn't any activity in the background.

Now we have a situation where a 1080p is maxing out a dual core that each core should potentially have 8+ times the processing power?

FWIW my current system@4.6GHz uses 2% CPU usage with HTML5 player in firefox when playing this vid at 1080p:

How do you enable/disable HW acceleration? I'm already using Chrome...is there a way to default it to HTML5, or is that only on YouTube that you can do it?

I'm still on Windows 7 64-bit, so it seems the latest for Haswell is the 15.36 line that only has 4280.

If my video clock doesn't budge from 600Mhz when I'm playing a video, then that means it's relying on CPU to do the decoding, right? When I play video at showtimeanytime.com, I see my core clock go up to 1150Mhz. But when playing the YouTube 1080p video linked above using HTML5 player within Chrome, video clock stays pegged at 600Mhz.

Try with IE instead of Chrome. If it solves it you know where the issue is.

G3258 should rip through all 1080p encodings with zero issues. It has to be a setting you're missing. Hell, even clocking it down to 2.0GHz shouldnt matter. I downclock mine when I want near perfect silence and it doesnt have any problems with video playback.

Not necessarily, though I'm thinking since he already has the CPU clocked at 4.4GHz he might've done that previously. To even get to ~1500MHz on the IGP he'll have to dial down on the CPU clock to something in the range of 3.8~4.2 GHz, that was the case with me, as for whether he can achieve such a high IGP overclock that'll depend on his hardware & software setup. Trial & error basically, besides I can get to 1350MHz with stock (adaptive) IGP vid but the board limits max CPU overclock to just 4.4GHz.
