How much does streaming affect performance?

[dkspooder]

I went and did my own micro-benchmark suite this morning because I was curious to see how much Xsplit taxes my system while under a game load.

 

However, I was not expecting this much.

 

 

I dropped at least 5 FPS in almost each category over the entire test. Mind you these are still well within the comfortable range of playability, i fear for those who play more competitive eSports such as CS:GO, where the latency and fps matter.

were you using cpu or gpu encoding. 5 fps is nothing.  :lol: also what settings 720p30? 720p60? 1080p30?

you should be using nvidia  shadowplay, that uses the built in H264 encoder on your gpu

Depends what kind of streaming

looks like crap at low bitrates, for streaming.

If you play Solitaire sure.  Twitch accepts a max of 3500kbps ingest, and at that bitrate, NVENC and any hardware encode will be utterly terrible.  x264 at 3500kbps is tons better looking at the cost of CPU performance.

I used my cpu for h.264 encoding, as it was sitting at about 30 percent utilization throughout. xsplit also caps you at 30 fps for non-premium. There is plenty of headroom for the cpu.

 

I can do these numbers again for dgpu encoding, if you like.

OBS for streaming? maybe?

Also take into account that I am running budget hardware. The 750 Ti wouldn't be able to handle that kind of a load simultaneously while gaming

the H264 encoder is a seperate thing on your gpu, it is designed to remove the performance hit
