MPC poor performance in Win7

[Apexi]

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.
*Disable Aero
*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 i7-930
*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?

Please open a Task Manager window (CONTROL + Shift + ESCAPE) and see if it informs what's the process that's eating the *PU(s).

Besides,

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 ;

Task manager can't show you the GPU usuage. But the CPU usuage stays at 5% when i'm watching a movie.

It's a bigg different between Haali and the internal filters on my 50" monitor, sp i need Haali or madVR atleast.


I'm out of ideas since all the settings are the same as before.

If you installed Windows 7 64-bit, are you using Media Player Classic Home Cinema's 32-bit version or the 64-bit version? I don't know if it is still true, but I think at one time Media Player Classic Home Cinema's 32-bit version was needed to use MadVR.

[Apexi]

I use Win7 64bit, but 32bit version on all the programs to watch movies

And are you using MPC or MPC-HC?

Have you tried whichever one you aren't using?

[jagabo]

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

Usually i use:
- FFDShow and madVR,
- but i've tried FFDShow + Haali
- FFDShow + Haali + Lav filters.

first uninstall all these - FFDShow, madVR, Haali, Lav filters
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 .....

I use MPC-BE x64 v1.1.3.0 on windows 7 with no problems, You might want to give that a try.

[Apexi]

Thanks for answers and sorry for the HC miss. Yes, i'm using MPC-HC, the latest one.

Tried only with LAV filter, but that gave me 99% GPU aswell.
To give DXVA a try is not necessary sinve my GPU is already maxed out. The CPU can handle it however.
