Question / Help Unable to stream 1080p without performance issues?

[Seigler]

Hello,

I've been struggling to stream at 1080p without having performance issues.

PC Specs:

Nvidia GeForce GTX 1080
i7-6850K @ 3.60GHz
64GB DDR4 2400

Internet:
Typically ~20-24 down

I've been trying to stream various games (Wildlands which I think is an issue of it being at max settings and the amount of CPU usage it takes so I'm not worried too much about that), PUBG (similar issue I assume, I recently lowered settings and it's not as bad), and League of Legends which I've always kept at max settings and never really had any issue with and typically get 120-130 FPS, however whenever I attempt to stream especially at 60 FPS it drops my FPS to around 60 or sometimes even slightly under.

The settings I'd like to run in OBS are:
Bitrate 6,000
x264
60 fps
1920x1080
faster

Note I don't have the logs because I've been trying numerous settings and always have an issue of either suffering in performance or bad graphics quality. I've tried running Nvidia encoding instead of x264 but it sometimes comes out muddied despite giving better performance.

I assume my PC is at least decent so I can't figure out why I'm struggling to stream at 1080p with 60fps. It seems with some games it's more of a CPU issue but for example with League the fact that I drop FPS so much whenever attempting to stream makes me wondering if perhaps I need a second GPU?

I watch a lot of streamers and notice people like aphromoo who maintains 130 fps while streaming at 1080p in 60fps and doesn't seem to suffer from any pixelation or blur, etc.

Any suggestions or input would be appreciated and if you think the logs would help I can definitely put some up with whatever settings you might need to look at and in whatever game you would need to see.

Thanks.

Log plz....which resolution are you using on your monitor, do you know that you need to limit your ingame fps to a value that your system can always deliver, to avoid bottlenecks?
Without a log, I'm not even sure, if your CPU is not fast enough or if the lack of an ingame fps limit is simply creating rendering lags.

I'm pretty sure x264 faster profile at 1080p 60fps is too much encoding load for your 6 Core/12Thread CPU on any game, that utilizes more than 2 Cores.
With 1080p x264 60fps encoding In PUBG I can barely avoid dropped frames with very fast preset on a 8 Core 16 Thread Ryzen 1700x @3.8GHz.

1080p60@faster is quite a task for an broadwell-e CPU with only 12 Threads and usually a rather low clockspeed.

I would recommend using veryfast preset and if that doesnt help use NVENC for 1080p60 although it will look rather bad in games like PUBG but League of Legends should be totally fine.
