Silly question: MSI Afterburner 4.3.0 - what is VID usage?

[Obakasama]

Hello fellow forumites.

Currently trying to troubleshoot a dip in Ultra Street Fighter IV framerates and I've managed to narrow it down to VID usage spiking up to 95%. I assume, VID usage refers to the voltage to the graphics card rather than CPU. Much searching didn't provide an answer for some reason...

Thanks in advance.

Background: Generally USFIV will run at 59.x fps using a suggested optimisation guide. Very occasionally framerates will drop with Afterburner registering approximately 30fps.

With the exception of VID usage spiking all other monitoring appears normal (CPU, GPU and RAM frequency and usage). Thermal margin of CPU was 58 deg C at lowest. Voltage rails seem to be in normal acceptable range according to HWMonitor.

Specs:
CPU: Athlon x4 760k
GPU: GTX 750ti
Motherboard: Asus x88-Pro
RAM: 2x4GB

I took this from superuser . com :

VID has nothing to do with the voltage on the card.

VID usage is tied to the built-in hardware H.264 encoder found on GTX6xx and higher cards. (I am not sure if AMD cards have a hardware encoder on-die)

A way to show this is by setting the video format under "Video Capture" in Afterburner to NVENC (Nvidia cards) and then pressing the benchmark button under the "Encoder" drop down OR by video-capturing within a game.

This will show usage since NVENC directly uses the hardware encoder on-die.

A rather late but correct answer. VID is also shown and described more clearly as "Video Engine load" under GPU-Z. – qasdfdsaq Jun 10 '15 at 11:54

Thanks for the response, dudio, I didn't come across that page and info during my searches so much appreciated.

The information there suggests video encoding process which is something I don't do. Throws up more questions for me as a result... I wonder if it includes playback as well. Looks like I'll have to try and find a process which correlates with the encoding or use of H.264 when those framerate dips occur.
