So I'm another newb to streaming... but I have been reading guides and googles alot about my situation (and also read the forum).
First my hardware:
i5 3570K @ 4.3GHz (ivy)
16GB DDR @ 2400MHz (DC)
GTX 570 @ ~850MHz gpu clock
Intel SSD raid 2x 180GB @ sata 3
Z77 chipset
Internet:
And my log:
My problem:
Stream seems to be choppy here and there, also I noticed that the fps (streaming @ 30 fps) in the lower right corner of the obs window struggle to keep up (bounces between 21 and 29 fps). So what did I do wrong or where is the bottleneck of my pc?
Note:
With additional programs (like browser and musicplayer, email, ...) running my CPU bounces between 15 and 30% while playing WoW (1080p, ultra, no AA, windowed). Framerate cap inside of WoW has been significantly reduced by myself to about 42 frames. With that framerate GPU load will not exceed 70%.
While straming:
CPU spikes up to 80% (but I have never seen a single core spike up to nearly 100%) and GPU spikes up to 90%.
So how can I fix that without sacrificing my streams quality (or how to even improve quality? I'd like to stream 1080p but seems to me my pc can't even handle 900p)
Thanks for your help!
