Question / Help Any tips for streaming fast motion FPS games at 720p?

[DEagleson]

So im planning to stream some Black Ops 2 gameplay with a friend of mine at 1280x720 30fps and i would like to know if there is any good tips on how to get a decent quality stream of it, since its a fast motion fps.

The kicker here is that i got a notebook so i cannot tap into the raw GHz desktop users got access but here is the specs:

Windows 8 Professional x64
Intel Core i7 2720QM at 2,2 GHz stock, but can turbo to 2,6 GHz with all 8 cores.
Nvidia Geforce GTX 680m (Wont really help livestreaming but including it)
8gb of DDR3 ram

I also got some upload tests linked below:

720p30fps at 3000 bitrate on the Veryfast preset should look pretty good.

If the performance hit is too much, you can look into using QSV on the new test versions, since you have a Sandy Bridge i7.

OBS uses the GPU pretty heavily to do what it needs to do, so your strong 680m serves you well, here.

Thanks for the quick reply. :)

While it would be nice to utilize QSV the Clevo P170HM notebook i got is not using switchable graphics.
I am thinking of getting a P170EM and salvage most of my hardware since i would only need a CPU. Seen a bit of test clips on the dev thread and im kinda impressed by the quality of QSV considering its hardware encoding, and if i get a i7 3920XM i should reach near desktop speeds as well.

For now il check out the stream settings and post a log and link to the video later.

I'm not sure, getting QSV working seems to require different things from different systems. You may be able to use it right out of the box, though. The laptops with built in switchable graphics seem to be ok with using it. QSV tends to be somewhere between Superfast and Veryfast quality, which is more than acceptable, especially considering you are encoding with 0 impact on the game.

It's worth looking into if you find performance to be an issue, and your internet connection should supply you with plenty of bandwith to get a quality stream with QSV.

Stream worked great and it looks like the livestream handled the faster motion.
Only bad part was that only a few people actually had the download bandwidth to watch it.
