Topic: svp index spiking each second

I have intel i7 3770k 4.1ghz, geforce 780, 1600mhz ram. No matter what quality i set, svp index is spiking a lot and i can see that on movie sometimes. I tried googling but didn't find much, i am using SMplayer 64 bit and i configured it by a tutorial website. I tried many different players and svp index was spiking always, more or less... I tried different amount of threads and various advanced settings, but nothing had any effect what so ever. Svp index is spiking a lot from 0.95 to 1.1, or 1.2 usually, or more sometimes.

Any ideas what is causing this ?

Re: svp index spiking each second

does this happens with any video size/format?

not sure it's something bad though as long as the video is playing smoothly

Ye. I watch 95% 720, or 1080. Different size from 1.5GB to 4+ And mp4, mkv and such, it happens always.

Re: svp index spiking each second

these graphs are NOT intended to check or control video playback smoothness
there's another tool for this - Utilities -> Fluency and tearing test

take MPC-HC and set madVR as a video renderer - does it work smoothly?

Re: svp index spiking each second

For smplayer it is quite smooth not teared, but sometimes it shakes a bit. I will test mpc-hc later.

> sometimes it shakes a bit

this usually can be solved by using "fullscreen exclusive" mode (the default behavior for madVR)
still not sure if it works correctly for mpv, but according to docs it must work in full screen with the "ontop" option specified

Finally get to switch to daum pot player 32 bit, works amazing at default settings. SVP index is 1.0 almost all times.
