Question / Help stream setup advice wanted

[suppaflex]

Hello all,

I would like to get your advice on the smartest stream setup for my situation and available hardware. I'm already streaming via Shadowplay to Twitch and that does work wonderfully well, but I would like to have an overlay and notifications, custom placement for my webcam etc. and as far as I know you cannot do that with Shadowplay.

My situation

Gaming Rig:
- i5 4440
- MSI GTX 750 TI (I use Shadowplay with this card)
- 8Gb memory
- Benq 144hz monitor
- Audio via headset (mobo audio)

I know that this GPU doesn't get me the frames to fully make use of the 144hz monitor, but this monitor is awesome, even with this GPU :)

- I also have an i7 Macbook Pro which I can use for the stream setup.
- External Mbox audio device

Lately I've been playing CS:GO a lot, but I also play LOL, Kerbal, AoE, or xbox one so I'm not pinned to one type of game and neither should my setup be.

These are the option I have in my mind:
1. Upgrade the i5 to i7 and stream from 1 pc (and get a capture card for xbox one)
I might also upgrade the GPU to get more frames for the monitor and do everything from 1 box with 2 monitors.

2. Use the i7 Macbook pro as a streaming box (and possibly get an USB 3.0 capture card)
This would be the cheapest solution for me as I would only have to get a capture card, but I did some research and OBS under OSX & USB capture cards may introduce a lot of efforts to get all things running (smoothly). The NGINX option without capture card would also be a solution but I guess I then have to still upgrade my i5 to i7 on the gaming rig?

3. Build a new Windows rig for either gaming or streaming.

What I like from Shadowplay is that it also includes all sounds (game & chat). I might have to all route that myself to the streaming computer but with new toys comes some effort to get it all running :)

I'm not partnered with twitch so I'm stuck with 720p/60fps max if I'm correct.

So the million dollar question. What would you suggest? Did I overlook any other viable options?

Hi suppaflex,

since you are not partnered, your only limitation is bitrate.
Iam not partnered too, so what iam using is 720p@60fps and 2500kbps bitrate.
Thats somehow sweet spot for me, so its only suggestion for you. You can always tweak something out :)
For that building/upgrading part.. i think there is no need since you dont want to "waste" money for equipment, which will be limited because you are not allowed to stream at high bitrate to use full potencional.

Atleast, thats what i think.

Peace

Hi Hrobnicek,

Thank you for your reply! That's an option too offcourse, just stick with what I have on the gaming rig. Do you guys think I have enough for what I want to achieve at 720p@60fps? Not sure if important, but I also run the OS from an SSD.

Cheers!

What i know, SSD has no effect on streaming/OBS. It will help you with other things like for example "faster" respond from OS, apps etc.
From my experience, i think you should be able to stream at 720p@60fps with no problem.
I streamed at this reso/fps with i5 3570k, and what i remeber only World of Warcraft was kinda harder to setup.
Beside that, everything was ok.

Peace

Hi buddy, thanks for replying. Just setup everything and played CSGO while streaming at 720p@60fps. I noticed some lagg during gameplay so I'll probably end up upgrading something. Not sure if I need to upgrade the GPU or CPU. Note that with shadowplay, I do not have an issue with lagging.

What would be wise to start with? I'm kinda thinking it's my processor, but my GPU is not that great too. What would be the smart step forward?

well, this is probably the question for someone else to be honest..
you can always check how much is your procesor stres during stream/gameplay.
If its cap 90%-100%, than yes, you probably need to upgrade or go down with settings, like 45fps/30fps and try it again.
Its all about testing.
Did the same thing.
Also, you are not dropping any frames or anything, so its probably just ingame lag. So realy dont know atm.

Peace
