Well, a long story short.Just switched over from WinXP to Win7 on my HTPC. I formated the HDD and did a clean install of Win7 as i always do.
All HD movies has played smoothly on WinXP, both 720 and 1080, but now on Win7 all movies lags and freezes, and sometimes the sound and image are outsynced.
GPU-Z show me 99% GPU usage constantly when i watch movies
I've used the same MPC settings for a couple years and it has worked just fine for me, but not now anymore.
Usually i use FFDShow and madVR, but i've tried FFDShow + Haali and FFDShow + Haali + Lav filters. But all set ups ends as before, 99% GPU usage
This is strange since it worked flawless in WinXP.
Things i've tried.
*Downclock and overclock the GPU
*Played the movie on another discs
*Set up the "High performance" in Power management
*Tried several Nvidia drivers, way back to 2012 drivers
And the HTPC specs.
*Intel X25-M SSD 160GB + several 1TB WD discs
*Corsair HX 850W
*Corsair Dominator DHX+ DDR3 1600MHz 6GB
*Geforce GT 520 "not the best GPU but it did the job in WinXP"
There's absolutely no temperature problem and all drivers are up to date
Any settings i've missed?

Thread: MPC poor performance in Win7
a) disable or remove most of the tasks listed in the Task Scheduler service ;
b) forget Haali Media Slitter, which is a "must-have" only for the exceedingly-fanatical anime fans ;

I use Win7 64bit, but 32bit version on all the programs to watch movies
Try using different readers, splitters, codecs, and output devices (I know you've done some of this already) until you figure out which one (?) is causing the high GPU usage. The look for a workaround.
On HTPC my proper to play on XBMC
XBMC have built in codecs and use DXVA acceleration
On my HTPC have Atom CPU and no problem to play 1080p videos
XBMC better use with media center remote

then install only latest Lav Filters, this pack contains splitters and decoders and you dont need any other codecs
what is this MPC - if it is Media Player Classic it is very old player, instead of this try MPC-HC, PotPlayer , VLC Player ......last two have integrated codecs in them, MPC-HC have no more internal codecs don't know why .....
