Re: PS2 - Steam Home Streaming


Tbh Input lag is barely noticeable, I've capped the bandwidth that streaming uses to 5Mbit/s as this prevents my weedy client laptop from becoming overloaded with data to decode...

But each host/client and network setup is going to be different, but this at least shows that even in beta with no particular tweaks made for PS2 that Home Streaming is pretty impressive.

Steam Stream Log for about a half hour session...

EDIT: Note, this ancient laptops X300 graphic chip doesn't have an H.264 decoder so its using the cpu to software decode the video, thats the biggest bottleneck on this particular setup. Note the line in the log...

"DecoderName" "libavcodec software decoding with 1 thread"

And thats my filthy stinkin TR alt, I feel dirty
