I have a problem with the GPU acceleration. When switched on the quality of the video smoothness is reduced.

I'm using a core i3 3310m CPU with the Intel HD 4000 Graphic chip.  I know that the the Hd 4000 is not very powerfull but I thought it would be fast enough for SD-Videos. 
I really like to use the GPU acceleration because without it I have a CPU usage of 50-80% for SD-videos and when it is enabled the cpu usage is under 50% for SD-Videos.

Is there a way to use GPU-acceleration with the HD 4000 without reduced video smoothness for sd-videos or have I to use only CPU-processing for best performance?

@MAG79 I have changed some settings in reclock and now it  shows a green colour . So everything is ok.

So for best performance I need Reclock?

I have installed it but I don't know how to set it up right.  I'm using MPC with madvr LAV-Video/Audio decoder and ffdshow video/audio and SVP. 

But Reclock is always yellow and not green.

The refreshrate of the video hadware  in reclock is 60.077Hz.

If you have a good graphic card it should be no problem playing games with 60fps or more without any   interpolation. 

I'm not sure but  I don't see any change for a motion interpolation in video games because the frames are calculated during the gaming in realtime and you don't know how the next frame would look like.

The 29,97 fps are shown on the screen by svp.

It is the same problem with movie_blood_diamond.vob.   With potplayer and it's integrated quick sync encoder  the video is played  to fast (about 10 seconds per minute) and audio gets    
asynchronous.

Using Lav or ffdshow with quick sync the video is played at normal speed but  seems  to stop every second for a very short but noticeable  time (perhaps some ms) (thats what I mean with falter) .

This playback behavior can be recognized with or without using svp. So it's  a problem with the quick sync encoder in Lav/ffdshow and potplayer.



@MAG79 Can you play the file with quick sync  without my mentioned problems?

Great! I will try it.

Edit:

Still have the same problem.  With quick sync these files are played to fast but smooth (potplayer)  or they are played at normal speed but falter every few seconds (ffdshow/Lav in MPC) with or without SVP.
With other encoders svp   produces a very smooth plaback  but  still  recognizes 29,9 fps.

Share this file. I will have a look.

Thanks for your response.

My Internet connection is slow so I will not uplod that file. But  a video-trailer  with same problems can be downloaded here.
I think that every trailer on that page have the same problem.

I'm using svp on my notebook. But I have only a core i3 3110m, so I'm trying to use Intel quick sync in ffdshow in order to have more CPU power left for svp. With H.264 videos it works fine but with mpeg2 I have two problems:

1) I can't get to work Intel quick sync for DVD-plaback. The single  .vob files from the DVD can be played with quick sync but  the whole video.ts file not.

2) I have some video-trailers  where ffdshow with quick sync plays the files with 29,976 fps but they have only 23,976 fps. 

The specifications of the trailers are:

I have tried ffdshow, Lav and potplayer with Intel quick sync and all have the same problem.
