Jack0r submitted a new resource:

How to use Quicksync? - Quickly explained how to activate and setup everything to use QuickSync

If you are not sure what QuickSync is, check this article.

Now let us first of all check if QuickSync is not already available for us. Open up your latest version of Open Broadcaster Software and go into the settings and then into the Encoding section. Below is an example screenshot of how it will look if QuickSync is not yet enabled on your System....

Advantage: Uses dedicated GPU to do h264 encoding, drastically reducing CPU usage.
Disadvantage: Somewhat lower quality video than x264

I have a G3258 x44 @ 4.4Ghz, the igpu is intel HD, Does the quick sync *quality improve with a beefier igpu? My GPUz info here:

The intel HD gpu description can be found here: -- It look's like it has a frequency of 350 MHz, which can be boosted up to 1250 MHz, so it should be able to match or exceed the performance of the HD 3000. The thing is I do not know if quicksync improves with a better igpu, newer instruction set, or additional threads/cores? My experience benchmarking here was not that great:

So far the G3258 has been a dream upgrading from an Athlon II x4, ..until I tested the quicksync quality.

Well, its unfortunately a bit complicated with QuickSync, as far as I remember from Sandy to Ivy Bridge Intel mainly improved the performance of QuickSync, from Ivy Bridge to Haswell now they improved the Quality.
But I have no real information about the differences inside each generation. I know even an Sandy Bridge i3 (mobile processor) can do 720p quick sync just fine, but not at a good quality for streaming. On my Haswell i7 the quality improved quite a bit, but it has the second highest iGPU version inside, the hd 4600. I think the hd 5200 is currently the best you can get from intel and was supposed to have the best quicksync performance (not sure if quality). (If I remember correct you can barely get this version for desktop CPU's anyway)
You can probably find benchmarks and even quality tests, but I could not find a real comparison between the different iGPU's :(. So I can only talk from experience mainly.

@Jack0r I was more comparing the quality of the video, less pixelation, noise. Do you have a sample video, on twitch preferably so that I can compare?

I only made a quick comparison once between x264 veryfast and haswell quicksync on my hd 4600 graphics chip:
The video unfortunately hit the download limit and cant be downloaded anymore :/ Some of the videos on my channel are done with quicksync too but I never marked them. I remembered one of the Batman videos was QuickSync but I couldnt find it in a quick search.
But I can probably record you something later, are you looking for a special scenario? Bitrate/Resolution? Or comparing a certain preset?

@Jack0r The default twitch settings I believe is what I had, 720p @ 2500 or 1080p @3500. Veryfast, and high quality on quicksync.. thx.

Isn't it with both Nvenc and Quick sync that it just doesen't utilizes the power to the maximum? I mean that if i for example are using Nvenc, it would not use all my power of my Graphic card, just some % of it. Why? It is the same thing with quick sync i guess. For my part, since im not using the IGPU, i would like the quick sync to use all of the power in it to make it better motion quality without pixelration

Oh they use as much as they can, but as far as I understood it, both nvenc and quicksync use dedicated parts of the chip or even their own chip. And its also possible, because of the different architecture of a GPU that parts of the GPU cannot be used for video-encoding because they are meant for different calculations.
The quality differences in the quicksync generations also show this to some extent, but to give you better examples (I have not forgotten you @kryteris but I was busy) I will try to do the example vids as soon as possible.

From the tech side, simplified, I can say, QuickSync gen 1 did not support optimization A or B because the chip was not designed for those. For gen 2 they added optimization A, for Intel this meant they mainly optimized the speed, for gen 3 of quicksync they added optimization B, which for Intel were quite a few features you already knew from x264. Mechanisms to compress the image better. Handle B/P/I Frames, etc. But they could not add optimization A or B using a driver, they had to do it in the next generation.

Hi, I am little bit confused... I have desktop with disabled intel HD 4600 inside of my CPU + GTX 760 GPU... Should I be able to use both at same time? I would love to use GTX for game while HD4600 would take load off for streaming. Is this possible?

To use QuickSync the iGPU (HD4600) has to be active, yes. But you should be able to use QuickSync without having to connect a Monitor to it. It depends on your mainboard (as shown in the guide) but if you can activate the Multi-GPU function, or whatever it is called in your Bios, you should be able to use QuickSync while keeping your normal GTX 760 running for everything else.
One more thing though, you can also use NVenc on that GPU, although the QS quality might be a bit better, try both if you have time :)

Can anyone help? when i try to add the 3rd display as extended screen i get a error about the graphics being unresponsive then my desktop goes black and my pc crashes


Sorry I cannot set up this on my i7 3770K x Z77X-UP4TH I just updated my bios and, I still cannot see the Multi-GPU option it has different ones on the Gigabyte menu. I tried installing several of the drivers in the video, but none of them want to run on my Windows 7 64 Ultimate...

The driver which is suppose to support HD 4000 video graphics on board with my i7 but, its not showing up on the installer it only reads

Click through the installer, and it says this operating system is not supported. Do I upgrade to Windows 8 or is there an easier option?

edit: They removed the documentation for it here

and here is where the file should be:™+Processors+with+Intel®+HD+Graphics+4000

Shit doesn't work. I also don't see an option to enable iGpu on my mobo settings it just lets me change the type of video mode and, I don't understand any of the abbreviations it uses. Acronyms are a cancer.

Hmm only thing I found in the manual would be Bios -> Peripherals -> Internal Graphics -> Set to Enabled. Init Display First should probably be set to PEG.
You might want to connect a real Monitor to the iGPU for testing (but keep one connected to your normal graphics card as well). And see if these drivers work:

And these drivers should be correct, the ones you posted too:
In general quicksync should work under win7 similar to win8.


I had alot of problems with getting quicksync to work on my computer with obs. The thing i found out was that i needed a BIOS update and then it all was fine.

Windows 10 made the monitor trick obsolete.
On my Sandybridge i5 2500k I still need a Monitor connected to the igpu, haven't tried the option to use a fake monitor, but without an active monitor I could not use QuickSync.
