Goal- Ingame Resolution 2560x1440p CS:GO - Stream at 1080p res with no pixel/grainy-ness and very smooth




Hello everyone, I am looking for some advice for my stream quality. It is very grainy and I do not know how to fix it. I attempted to switch to 1920x1080 res ingame and it still is grainy -

Do I need a capture card? I attempted it at 30fps and you can still see the pixels when I turn in game.


I currently am on a i7 2700k that is oc'd to 4.7GHz with 1 680gtx.
I am using a 1440p monitor.


As you can you see in the video, my ingame resolution is 2560x1440p and my video settings in OBS is "custom: 1920x1080" since Intel quick sync doesn't go higher than 1080p.


ANY information would be greatly appreciated!

Quicksync needs a whole lot more bitrate to look okay, sandy bridges quicksync overall wont be able to statisfy you in any way. That plus 1080p which in itself already requires a really high bitrate to stay clear especially in fps games.
So your goal is not possible at all.
If you really want to stick to quicksync you should downscale to at least 720p and see if thats looking good enough for you, i highly doubt it though. Your cpu since overclocked, should be able to handle cs:go and a nice looking 720p stream with just x264 instead of quicksync, so you might want to give that a try.

Overall, forget about 1080p, if you would stream rts or moba games or retro stuff, sure 1080p will produce good looking stuff on lower bitrates but for fps its just not viable.

dream killer :(

if i purchased a capture card, would this eliminate bitrate problems? Also what should x264 cpu preset be? (when I made it 720p it became smoother)

A capture card in a 1 pc setup is just luxury, it doesnt reduce bitrate or cpu usage at all, it just replaces window/monitor/gamecapture. Even in 2 pc setups it wont reduce the bitrate, some have onboard encoders which are actually worse than quicksync.

Preset just start with the default veryfast, you can of course experiment if your cpu usage is still low and go to a slower preset like faster or fast, but it might impact your games performance if your cpu cant keep up with it, also the gain is minimal in comparison to the extra cpu load.

Other then that bitrate is the most deciding factor, throw more bitrate at it and it will automatically look better but you are at 3500 which is practically twitchs recommended maximum bitrate. Lower resolutions will look cleaner at the same bitrate but you will lose the clear text and stuff.

ah i see, will have to play around with it, thanks for your input! Is it impossible to stream at 1080p at 60fps smoothly for games since Twitch limits bitrate at 3500? (Unless i get partnered, which I high doubt will happen anytime soon)

At this point in time streaming at 1080p60 is a terrible idea in general, regardless of your setup. Aside from bitrate limitations that will make most content look bad, there are technical issues like Flash having trouble decoding it at full speed on most PCs. If you want to stream at 60 FPS then use 720p or maybe 864p. If you want to stream at 1080p use 30 FPS.

Yes thanks for info! One question, for "filter" under video settings, is bilinear(fastest) the best option for this?

 

[Sapiens]

Downscale filtering can have varying results depending on the source content. Test them to see which you prefer, there is no "best" option.

You should use the highest quality one, not the fastest one, IMO. So that would be Lanczos.

Since you're playing an FPS I would go with 720p60 rather than 1080p30. Those are you best two choices, by the way. So that's a 2x downscale for your base resolution.

A capture card will only do you any good if you've got a second computer doing all your encoding. For a single computer PC game setup, it won't do anything for you.

After you stream, look at these lines in your log file:

07:44:07: Total frames encoded: 12357, total frames duplicated: 31 (0.25%)
07:44:07: Total frames rendered: 12341, number of late frames: 5 (0.04%) (it's okay for some frames to be late)

If those lines for duplicated and late frames are under 1%, then you're doing well. If they're a lot under 1% (like they are in the example above), then you can use the next slower preset to increase quality more. So if you started at Very Fast, and see the above result, try Faster next time. If its still under 1% for both, then try Fast. If over 1%, then go back to Very Fast, and if in-between, stick to Faster. Be sure to stream high-motion content for at least five minutes each test for accurate and consistent results.
