Choose decoder CUVID as shown at the picture - OK, reopen video.

About splitter. What splitter do you see in the menu Play - Filters?

If you see there Haali too then you need not to change it.

i'll have to continue this tomorrow, i'm gonna knock out for the night.

thanks for all your help so far.

Then try to change splitter for your mkv-file.
I know three variants:
- Haali matroska
- LAV
- MPC Gabest

Test smoothness by playing Avengers with SVP.

Please download this 60fps video: http://www.svp-team.com/files/demo/space_60.mkv
Run it and compare smoothness visually. You can exit SVP while play this file.

LCD

and before gaunt's adjustment, it had made it worse before.

What monitor do you use to watch video with SVP (CRT / LCD / DLP / Projector)?

Try to change:
- SVP shader to 23.
- Motion vectors grid to 16 px.
- Decrease grid step to By two with local.

What you see if press Ctrl-Win-T and switch to fullscreen mode?
Orange line moves smoothly and evenly?

Please show your additional information from SVP tray menu - Information.

dropped frames went down to only 17 this time.

It's still doing the slide show effect during any faster than normal movements. It's almost like it only plays frame 1, skips 2, then plays frame 3.

and during these scenes, it doesn't say any frames dropped.

dropped 39 frames
It is not bad. Ideal is 0. But you need to reset this number after fullscreen play start by Ctrl-R.

If smoothness not enough for you then you need to customize file override.js. Remove double slash (//) from these lines and point new values:

smooth.scene.limits.scene        = 2000;
smooth.scene.limits.zero         = 100;
smooth.scene.limits.blocks       = 51;

analyse.main.penalty.lambda      = 0.6;
analyse.main.penalty.plevel      = 1.7;
analyse.main.penalty.lsad        = 4000;

It is custom values by gaunt from this Russian topic.
Some places of scene change can be missed by SVP and you can see morphing of pictures in such places.

I ran the test in the Avengers action scene and over 5 minutes it dropped 39 frames.
