I just decided to go back from Complicated Shader to Standard Shader setting, I do find the amount of extra artefacts unacceptable. I am watching on 2,50m wide screen by the way.
Thanks for the advice about uniform, will try that! I am using profile default settings now, except for Artifacts Masking, which I changed from Disabled to Weakest. This works best for me (smoothness versus artifacts).
Yes I tried custom resolutions, I did not work.
Thanks! Strangely enough I found a bit different description on the wiki of wat complicated shader does. But this is very helpfull!
Unfortunatly my JVC HD350 does only accept 24/50/60 hz refresh rate and not 48 or 72.
More artifacts = less smooth and vice versus. Try it on different content.
I suppose you ment: more smooth = more artifacts?
Maybe I should rephrase my question:
When using profile 5 (svp3) and having idle cpu cycles left, what settings could I change in order to have less artifacts without changing smoothness?
Of course I test as well, but sometimes this is very subjective and therefore I am looking for theoratical preferred settings first, then testing (as opposed to just changing settings randomly).
My CPU has some room to do some extra processing ;-)
Does setting the SVP shader to complicated instead of default lead to better results? Better as in: smoother and less or same amount of artifacts?
Or does it create more artifacts as well?
I am using profile 5 settings and looking for a way to finetune settings in order to decrease artifacts or increase smoothness without creating more artifacts.

I was quite surprised to see by the way that the GPU (Geforce GTX750), frequently was at 90% (but never 100%). Must be MadVR working hard I guess.

I thought it is solution
No it's not, it's a workaround ;-)
I installed a better CPU cooler and 3 extra case fans. CPU back at 4 GHz and running 15 degrees cooler now :-) Problem solved, no more stuttering video! :-)
Everybody thanks a lot for your help and suggestions.
Save the congratulations untill I have fixed it ;-)
Nintendo Maniac was right, my cpu is throttling from 4GHz to 1,4GHz at the moment video playback is stuttering. When I underclock my cpu from 4 GHz to 3,8 GHz it does not happen anymore. CPU temperature goes up tot 62 degrees C. I guess I have to replace my cpu cooler a water cooled solution.
Actually I don't know as I watch movies on projector JVC HD350 mostly ;-)
Onkyo is PR-SC5507 surround processor.

Ok. How many displays has your PC?
Do you know that really smooth video can be only at primary display?
I have two displays (Tv and projector) but only one connected at a time, switching between both with my Onkyo surround processor.

Good adapter with high performance. madVR must be better choice. Of course if you control GPU load. You can use GPU-Z for it.GPU decoding in SVP, where can I enable it?
MPC-HC has internal decoder: LAV Filter. You can choose NVIDIA CUVID acceleration into it.I am using Kodi DSplayer build with madVR as video renderer and reclock as audio renderer
So. I don't know about decoding settings in Kodi. In madVR check Automatic Fullscreen Exclusive mode option and another options in the general settings tab. Try to enable them. They must help.
I use Exclusive + use Direct3D 11. Some times ago I used windowed overlay.
Fullscreen exclusive and Direct3D11 were already enabled (apparently this is the default) in my madvr settings.
I did enable CUVID in Kodi (it was on DVXA2 before), I did not notice any difference though.
I changed profile from 5 to 4 and that works a bit better, but still the same stuttering issue every minute or so in every movie (not only complex scenes). So I am going to check cpu temperature and throttling!

sounds familiar o_O
http://www.svp-team.com/forum/viewtopic.php?id=2851In that case, what happens if you disable GPU acceleration in SVP? Maximium performance would be worse, but maybe it'll be consistent?
I'll check that as well, thanks !

Owwww, that's a good one!! I will check cpu temperature and whether it is throttling or not !!

He did not say his OS; for all we know he's on Windows 10, and Win10 users should use "DXVA2 (copy-back)" instead.
If that doesn't solve the issue, try increasing the amount of processing threads. Another 8350 user had to set it to something like 21 threads.
I am on Windows 7 Ultimate 64 bits
I am using a card with Nvidia Geforce GTX-750.
GPU-accelaration is already enabled, but I cannot recall to have seen an option named GPU decoding in SVP, where can I enable it?

I will check the D3D fullscreen option!
Thanks so far.
I am using svp3.1.7 on an AMD FX-8350 4 GHz 8 core CPU. I am using profile 5 (as recommended by the performance assesment). Video is smooth and artifacts are tolerable, but already soon the CPU hits 90% or more and video gets stuttering. All 8 cores are used.
I am watching 1920x1080p@24fps content while outputting 60 fps by SVP.
Even when tuning back both motion vectors precision and motion vectors grid one step, this still happens (but less frequent).
Any idea what could cause this?
Thanks for any hints.
I don't understand, FX8350 has 8 cores and no hyperthreading, so amount of threads should in my opinion be 8-1=7
You mentioned 15 core, 30 instead of 19 threads, and it should be 20 to 21, what do you mean??
I am interested because I also have FX8350 cpu.
I experience exactly the same (SVP4 more (HALO like) artifacts and therefore reverted to SVP3 as well untill this will be resolved.
Why 30fps? Most movies are shot in 24fps.
Hi,
I spent hours, days , weeks in order to try to get an acceptable compromis between smoothness and artifacts and finally came to the conclusion that I probably will never succeed unless I have some reference to compare between settings.
So my question is, are there any test movies/clips that I can use to finetune SVP4 settings to my taste?
Thanks!
Ronald
Thanks a lot for explaining! :-) One more question though, what exactly do you mean by "more performance" ? More smoothness? Less artifacts? Less cpu usage?
Totally clear now, thanks a lot!! :-)

Ok let me explain a little better what I am trying to ask ;-)
When creating a profile it copies settings from the automatic profile. However, I already changed the slider (better performance vs better quality) so this I assume, changed the settings of the automatic profile.
After doing a performance assessment again the slider stays at the same position. So, how do I get a new profile based on settings that were determined from the first performance assessment (before I started changing the position of the slider)?
Hi,
I created a new profile (I prefer 1.5m instead of adaptive) in SVP4 and played around with the settings in that profile.
Now I would like to revert the settings of my self created 1.5m profile to those determined best from the perfomance check. How can I do this? Just run the performance check again?
Best regards,
Ronald
