AMD VCE Support - Latest Steam Beta

[neodoughnut]

Guys,

Just quickly, is there now support for AMD VCE with the latest Steam Beta? if not, does anyone have any information on what the current status is?

Thanks

Steve

I haven't seen anything in the changelogs yet regarding AMD VCE support, so it's unlikely that it exists.

But am I correct in stating that there is now NVIDIA hardware encoding support? I am looking at buying a new graphics card and I would prefer AMD as they have more bang for the buck at the moment.

Yes, there is support for Nvidia Encoding, even in DX11 games!

Your question has already been answered, so I'll just add this: if you have an Intel CPU with quicksync support, you can use that. If you do have a quicksync-enabled CPU, here's how to use it for Steam hardware encoding:

1. Go into your BIOS and make sure the integrated GPU is enabled. Some label it clearly as simply enabling the igpu, others label it as something along the lines of "onboard multi-monitor support".

2. Right click your desktop and choose Screen Resolution. Click the Detect button, and it should show another display (even though it's not connected).

3. Click the newly detected display, and tell it to force connect as a VGA device.

4. Make sure the display is connected (it will change from gray to blue) and make sure it's set to extend your desktop to the new fake display. Note that windows will think the new display is actually there, and you can move your mouse over to it, so be careful of that.

5. Turn on steam hardware encoding and enjoy.


Explanation of why that's all necessary: Quicksync is only enabled if a display is connected to the integrated GPU. This makes it think there's something connected to the iGPU, and enables quicksync as a result.

@Martelol.

Thank you for the guide unfortunately I have an i7 950 with a 290x i recently bought.
I am planning to overclock it as I haven't got round it yet, and I was wondering if it would make a big difference at streaming compared to stock speeds?

Cheers

Depends on how much of an OC you get out of it :)

I just upgraded my CPU from a similar setup actually - I had an i7 920 @ 4.0GHz and a 290x. I still have the 290x and have upgraded the cpu to an i7 4790k. The 920, even at 4GHz, could not stream at 1080p60 in a number of games. Some would handle 60fps fine, most would dip into the 40s and 50s, and a couple would lock at 30. I never tried streaming with a lower CPU clock though, so I can't tell you how much of an improvement you'll see - just that you shouldn't expect 60fps at 1080p in most things.

VCE is probably the lowest latency encoder (at high bitrate) out there (16ms). IMO, perfect for in-home streaming. The idea behind VCE is to enable wireless monitor support and still provide high bitrate/quality and low latency.

lowest latency 16ms? lol?

It's funny how your name suits you. You spew out crap like you're braindead... or you could say... Headless!

Most IPS LCD monitors have a 16ms latency compared to CRTs. TN LCD quoted times are grey to grey switching.

16ms latency is considered low for in home streaming.

well obv u don't know what you are talking about when u comparing lcd latency with encoder latency...

I think what Quadrupole is saying is your best response is "lowest latency 16ms? lol?" which is great input for the topic at hand. so for that, we all thank you for your input.

to put things into perspective, my last tests with in-home streaming my average latency (1080p60fps) is around 80-100ms end-to-end with about 800mb/s stream connection over wired Gb. My quadcore was also pretty much at 80-90% usage.

What VCE promises is what in-home streaming has been after. low latency encode AND decode, via use of lower buffer, latency contrained VBR, and Intra Refresh, PLUS taking almost ALL the encoding load from your CPU to VCE which is built in to 7XXX and R7/R9 GPUs and modern AMD APUs.

On the other hand, you do have GTG LCD response times which will add latency to any setup. I think he was using that as a comparison to latency that would already be present from a console to an LCD display.

Also, 16ms is tweak-able, was based on lower bitrate, (i.e. 6mbps) tests.

you really are dull arent you? i was providing context for how little 16ms of latency is.

if people dont mind the additional latency switiching from CRT to ips LCD, how is 16 ms for in home streaming be considered bad at all?

it's not bad, far from it... but it isn't LOWEST like he said... it''s funny to me how amd guys considering their stuff is always the best :) anything below 30ms for streaming is like playing on local machine.

I guess we wont know how it stacks up with things like quick sync until In-home Streaming utilizes it.
