Question / Help Quicksync help. High CPU Usage.

RivalTV · Feb 18, 2014

Hey guys, I ended up seeing Trexid's post on the OBS forums regarding Quick Sync, and when I saw he was setting his CPU Preset to Medium and lower and only getting about 10%, I had to try Quick Sync.

I followed Trexid's installation instructions on this OBS thread[1] . Enabled iGPU in my BiOS, installed the most recent drivers for the Intel HD Graphics, I have the most updated version of OBS, and extended my display.

I connect my Xbox One to Live Gamer HD. When I try Preview Stream, I see a picture, but the FPS is only ranging from 25-30 when I have it set to 60 and I'm getting a WARNING! message in the bottom left of OBS that says "Warning! Taking too long to encode skipping frames". When I check my CPU Usage, it's ranging from 75%-84% with my Xbox idle. Am I missing a setting, or doing something incorrectly? I'm trying to stream 720p60fps.

My Hardware

Xbox One

Live Gamer HD

i5-2500k overclocked to 4.5 ghz

Gigabyte Z68AP-D3

GTX 560ti

Intel HD Graphics 3000

My OBS Settings

Encoding tab

Use CBR is CHECKED

Enable CBR padding is CHECKED

Use Custom Buffer Size is NOT CHECKED

Max Bitrate is 3500

Codec is AAC

Codec Bitrate is 128

Codec Format is 48khz stereo

Video tab

Video Adapter is Intel(R) HD Graphics 3000

Base Resolution is CUSTOM: 1920 x 1080

Resolution Downscale is 1.50 (1280x720)

Filter is Bilinear (fastest)

FPS is 60

Disable Aero is NOT CHECKED

Advanced Tab

Use Multithreaded Optimizations is CHECKED

Process Priority Class is HIGH (also tried NORMAL)

Scene Buffering Time is 700

Disable encoding while previewing is NOT CHECKED

Allow other modifiers on hotkeys is CHECKED

x264 CPU Preset is MEDIUM (also tried FAST)

x264 Encoding Profile is MAIN

Keyframe Interval is 2

Use CFR is CHECKED

Custom x264 Encoder Settings is NOT CHECKED

Allow 61-120 FPS entry in video settings is NOT CHECKED

Use Quick Sync is CHECKED

Use custom x264 settings for Quick Sync is NOT CHECKED

Use Nvidia NVENCE is GRAYED OUT

Quick Sync Preset: 1 (Best Quality)

Force desktop audio to use video timestamps is CHECKED

Global Audio Time Offset is 2

Use Mic QPC timestamps is NOT CHECKED

Bind to Interface is DEFAULT

Automatic low latency mode is NOT CHECKED

Latency tuning factor is CHECKED

Hopefully somebody could help me out and let me know if there's something I'm missing in regards to Quicksync. I'm getting the same CPU Usage as x264 encoding, the only difference is I don't drop frames with x264 encoding. I wanted to try out Quicksync to potentially lower my CPU usage.

I forgot to add, when doing a speedtest to Chicago, IL (which is the Twitch server I have selected under Broadcast Settings, I get 8 ms Ping, 121.04 Mbps download and 23.29 Mbps upload.

If you guys need any other information, let me know.

Well, first choose the right video adapter in settings>video. Currently OBS is doing all its work on the iGPU which is bad, because you need to free up the iGPU for all the encoding. I'm not entirely sure why your CPU usage is so high when using QuickSync but make that change first and see if it helps.

BTW, changing x264 presets when using QuickSync has no effect on quality, they are different encoders. Which post were you referring to?

Hey Krazy, thanks for the reply. I fell asleep super early last night, sorry for my late reply.

Under Settings > Video, I have the Intel HD Graphics 3000 card selected, was this not correct? Do I want to keep the Video adapter on my Nvidia GTX 560 ti? If so, I must have read the post incorrectly.

The post I was referring to was http://obsproject.com/forum/viewtopic.php?f=7&t=7597. In that posts he was nice enough to post the directions he took to make it work.

Method:
- Enable the intel GPU in the bios
-- http://www.youtube.com/watch?v=yvf05jVbPiU
- Install the latest intel HD graphics driver.
- Follow this tutorial to set the display as active in windows
-- http://mirillis.com/en/products/tutoria ... ktops.html
- Update OBS to .57b
- Quick Sync checkbox is now available!
- Set the Intel HD Graphics 3000 as the primary card in OBS.
- Set my x.264 preset to medium and below!
- high priority
- 720p @ 60FPS on my Aver Live Gamer HD and on my video settings in OBS.
- Bitrate 3000 / Buffer 2500

I start streaming and have a friend monitor my Twitch channel while we discuss on Skype..

I check my processor usage.... 10%... yes... TEN PERCENT! I'm streaming amazing quality video with minimal resource usage. This technology is going to literally flip my streaming experience upside down in terms of quality and an resource usage.

So I followed everything he said above, and the logs in my original post is the issue I'm running into.

Just something to note, not sure if it was intended. I'm using an r9 290 gpu and if I select it as the video adapter I won't get anymore than 40-45 fps, but when I choose my HD4000 I get a constant 60 fps (this is without quick sync).

Was this directed towards me? Wasn't sure.

Badzyy · Feb 19, 2014

Nah man was towards Krazy, just something that i've figured out while playing with settings.
Pretty much can't stream at all with my dedicated GPU selected, not really sure why. Haven't tried with the newest update i'll give it a go and post back later.

Badzyy · Feb 19, 2014

Got the same results with new 0.612b, one thing though, it's an ExtremeCapU3 and it's plugged in through USB not into the GPU's HDMI. Could that be why it doesn't work well with the GPU selected?

I don't mind that you're piggy backing on this thread, I just don't want somebody to ignore my original problem because you've added the new one that's not Quicksync related.

Quoting my latest reply here.

RivalTV · Feb 20, 2014

Krazy, changing my VIdeo Adapter to my stand alone card worked. When I streamed 720p60fps without Quicksync, I'd get about 90% CPU usage. With Quicksync I didn't go above 40.

Thank you!

Question / Help Quicksync help. High CPU Usage.
