Topic: 2500k@4.5ghz + 980ti... studder and low settings

like the title says, 2500k@4.5ghz and a gigabyte g1 980ti.

im playing 4k videos ripped from youtube and outputting hdmi to my 65" lg 4k tv.... as well as a 27" 1440p monitor through dvi.

on the svp control panel in my tray bar i can set the preset.  anything one click higher from the left (high performance)i get massive studder and lag.  set to film, and artifacts masking is at low... though i haven't really tried playing with that settings.  do frame rate conversion is on at the top.... it does look good on screen, svp comes up at the beginning of videos and i can see the difference between 24fps and 60fps, but in certain video moments i see the artifacting and some frame hiccups, but not too bad.

but shouldn't i be able to peg the slider out?  i mean, what are the horsepower requirements?  surely one doesn't need an overclocked i5 just to run bare minimum, let alone the strongest single gpu graphics card on the planet to sustain one step higher than the lowest setting?

thanks all.

windows 10, latest nvidia drivers as of 1/21/16, 8gb ram, etc etc etc, recent install of svp.

Re: 2500k@4.5ghz + 980ti... studder and low settings

If your CPU utilization is lower than 80-90% (check in SVP via "Utilities" -> "Performance Monitor"), you can try the following:


1. Set your LAVfilters decoder to "DXVA2 (copy-back)"

1b. If you have the drivers for your Intel integrated graphics installed, you can alternatively try setting your LAVfilters decoder to "Intel QuickSync"


2. If that doesn't solve the problem, manually increase the amount of threads that SVP uses via "Application settings" -> "Additional options" -> "Processing threads"; set it to the smallest value that gives you perfectly smooth video.

4K can be processed with hardware decoding. For that purpose video must have AVC/h264 format. Not HEVC/H265. Check it.

To elaborate, it must be AVC/h264 8bit.

The following cannot be hardware decoded on your setup:

AVC/h264 10bit
HEVC/h265
VP9 - the default format on YouTube

Re: 2500k@4.5ghz + 980ti... studder and low settings

just to report back.  i did use handbrake to convert one of the files i downloaded from youtube to h264.  this did make a difference and i can move the svp slider to about halfway.

but im still getting about 1 frame dropped every 3-4 seconds though.  i scaled back all my madvr settings to performance but that didn't do much(dxva where available), at least for 4k h264 or hevc/h265.  with svp off i can run some pretty extreme madvr settings without losing a frame, but svp definitely takes some horsepower.

when i go into the svp/application settings/gpu acceleration/ and swap between "no acceleration" and 980ti it doesn't make a difference at all.  using msi afterburner to gpu statistics show that my gpu isn't even going past 535mhz.  i believe my gpu isn't even being used and its all on my 2500k doing the heavy lifting.

i found a thread that says win10 nvidia drivers and later are broken.  i will use display driver uninstaller to flush my drivers and give a win8 driver that was said to work nicely with svp a try... even though im on win10.  i will report back my findings.

mind you these studder are at 4k only.... 1080p bluray h264 rips seem to run smoothly at high madvr+max svp settings.

> HEVC/h265

h265 can be partially hw-decoded (so-called "hybrid video decoder") on NV cards using "CUVID" decoder
sadly it will hang on Windows 10 big_smile
