We appreciate your feedback on this matter. At this moment these are beta drivers that are provided as-is.
We suggest that you review the information available on this article:
If you are not using Microsoft* Windows* 8.1, and just using Microsoft* Windows* 8, then use the drivers that have been officially released for this platform and provide the dxdiag report from your system.
Thanks I understand, I only installed the beta drivers in hopes it would return my Win 8 system to it's former Win 7 smooth-perfection days.
The Windows 8 Media Center x2 herky jerky problem happens on the latest and previous official intel drivers too. It has been a problem since the very beginning of Windows 8 installation for me and others.
The problem is confirmed by others on TheGreenButton forum. Windows 7 latest drivers = Great, Windows 8 latest drivers = herky jerky. Please make sure the Intel devs have a chance to replicate the problem. Here is a test clip.
Open with Media Center in Windows 8. Press the fast forward button once.
Here is a side by side comparison I just made. If you don't notice it right away, watch the bus, cars, train move.
NVidia Quadro 1000M (i7 Laptop on the left) vs Intel HD4000 (i7 desktop on the right)
Remember this is at fast forward >>, audio pitch is reduced to sound normal. The left is so smooth it looks natural even though it's x2 speed. The right is herky/jerky, you'll notice it the most while panning or cars moving etc.
No problem, here you go.
I uninstalled the Beta driver package and installed the latest
Intel HD graphics Driver for Windows 8 x64
File name: Win64_15319.exe
Download Date: 05/10/2013
Per your request, I just confirmed that "VLC Player" can Speed Watch MCE DVR *.wtv files smooth at 1x/1.5x/2x/etc on both my NVidia based laptop and my Intel HD4000 based HTPC. For some reason Windows 8 Media Center speed watching playback with HD Graphics chips are not smooth for myself or anyone else. Multiple people have confirmed this on TheGreenButton (Media Center) Forum. Again Windows 7 is smooth, so something is not optimized right on the intel Windows 8 HD drivers.
Please let me know if you've replicated the buffer/lag stutter. I provided the example above.
Speed watching is great for watching twice the amount of TV in half the time. It plays with my head when it's herky jerky. It's very smooth and natural looking & sounding when it's right.
Thanks for looking into this! I'd hate to have to avoid or not recommend Intel Graphics HTPC's to my friends in the future.
I have sent you private msg with dxdiag report from current driver (3316), although you did not answer if there research and response that I missed. It is fairly simple to install Windows 8 Pro properly on some Intel motherboard/CPU with HD 4000, add Windows Media Center, record a show, then playback recording and click the fast forward button once (should result in approximately 1.5x fast sound and smooth video, but Intel graphics end up with jerky video).
