Odd behavior after Win7 updates

This happened once over a year ago, and then mysteriously straightened itself out...now it's happened again, right after several Windows updates were installed.

System 1 in my specs has been stable for quite a while, and the footage I use almost exclusively is 1080/24p AVCHD from a Panasonic AF100. Always has played back flawlessly at best/full full frame rate. After the last Windows updates Tuesday night (I'll check to see exactly what they were) there is severe stuttering and the frame rate displayed beneath the Vegas preview monitor oscillates between 13-19 fps about every 2 seconds.

Interestingly, when I drop a Color Corrector plugin on the track, no adjustments made - just drop the fx on, it instantly begins seamless playback at 23.98 again at best/full. GPU acceleration is on, so perhaps the plugin is taxing the CPU enough that the GPU is taking over. But still very odd. And why did my performance decrease to begin with?

Edit: Dont' think GPU acceleration has anything to do with it. GPU off - still 13-19 fps.

Found that a few security updates and Microsoft PowerPoint Viewer Service Pack 3 had been installed. I uninstalled PP viewer SP3 and, at least in the first few minutes of testing, seem to have regained normal performance again. I'm not convinced that was the cause, but who knows. Any ideas?

I had some updates mess with the raid 0 drives but it didn't kill them. They just gave a warning that they were messed up. Opened up the Intel Raid stuff and reset to normal and they were OK.

Make sure Windows update KB2670838 did NOT get installed as this has messed up more than a few computers everywhere, Vegas users included.
Google it and see what I mean :(

Mike, thank you. 2 days prior to the updates mentioned, THAT update was installed as was IE10. Removing both.
I've always had this computer set for manual updates, but I think when I allowed the last update for Security Essentials, it set everything to automatic. Back to manual.

I think that was it!
Before I uninstalled the Evil Update I tested a bit further and it was only the clips from my RAID that were suffering. Footage stored on internal drives played fine. Now everything is playing nicely again.

Thanks again, Mike.

Larry, I'm glad I could help. That particular update has been responsible for all kinds of grief :(

Something to be aware of - when I was Googling this MS update, I saw complaints from many other users who claimed that IE10 (of which this evil update is a key component) was installed on their systems even though Windows updates was set to manual install rather than automatic. I also saw dozens of complaints about the update being automatically REINSTALLED within days after they uninstalled it. Might be worth everyone taking a look.

I have found through navigating several "SVP issues' sites that most of the SVP 11 & 12 issues people have been encountering all have to deal with WINDOWS 7 compatibility problems. Having been an AVID MC editor that switched to SVP10 I always wondered why AVID recommended turning off WINDOWS' Themes and Special Display settings where SVP didn't. EVERY issue I have had with SVP 10, 11 and then now 12 has been FIXED with setting the compatiblity settings on each version. Right click on the SVP ICON, click Properties, click Compatibility tab. Check the box to Run this program and SELECT Windows 7. (I know this sounds dumb, but it works) AND select Disable desktop composition. Here are the problems it fixed for me in SVP 11 & 12:
1. STABILITY - very few crashes now vs. every 15-30 minutes.
2. Jittery video playback - I now use Full or Preview-Full
3. Playback of large .mov files
4. Use of New Blue Titler Pro - Could not even open it
5. Faster Start-up and opening (bonus)
6. Smoother rendering in 720p and 1080i to internet and AVC creation.
7. Inconsistencies in previews of files as Thumbnails

Try it, you'll see. System Specs:
SVP 10d & 10e, 11 (build 371 & 701), & 12 (563); Win 7 Pro SP-1 64; Intel i7 2.8 GHz; Gigabyte P55A-UD4P; 8 Gig Corsair DDR3; nVidia GTX-660; 5x 1T Barracuda SATA; 2x LG Super Multi-Blue BD, 2x Pioneer DVR-118L; AVID MC 5.5, Adobe CS5, Avid Liquid 7.1, Cyberlink PD7, 8, 9; Avid Studio, Pinnacle 9, 10, 11, 12, 14, 15.

I tried your suggestions on my Vegas 11 installs to see if there would be any difference. I ran earlier builds of 11 in Win7 compatibility mode, but the last didn't need it, but I gave it a try anyway to see if there was improvement.

Compatibility mode in itself made no difference on the 32 or 64 bit versions that I could see.

Disabling Desktop Composition in conjunction with Win7 compatibility mode on the 32 bit build gave me lots of external preview problems, i.e. display would go to black after 5 seconds or so and wouldn't return to normal until I stopped playback. Then another 5 seconds, then black.

The 64 bit build would hang every time I tried to enable external preview. Never got anything on the external display.

This may be another example of systems with different Windows updates installed, drivers, etc. - so many variables. Glad it worked for you.
