I have been extensively using steam in-home streaming as my default way of playing Steam games for about a year now. I have a gigabit network with a dedicated gigabit switch and my computers are well set up for the tasks. The host is on Windows 10, previously 8.1 and client on Windows 10/Steamos, depending on my mood.
Since my network setup is so ideal for the task, I've been using the "beautiful" setting and "unlimited" bandwidth on the client side for decoding. It's been working great with very low latency and very good quality. However, as of about a week ago, I've noticed a huge drop in streaming quality with colours washed out and compression artifacts. The stream is still fast and reliable, just a drop in quality. I did notice that where once my estimated bandwidth was around 600mbps and varying around that point it was then limited to 30mbps and was rock-solid limited to that point. I verified that my settings were set to unlimited, but 30mbps was the hard limit.
I solved the problem by opting out of the beta and all was back to normal. However, last night the changes were pushed to the stable client (I presume) and the issue is back. Is this something anybody else is noticing? Can I get back my high-quality unlimited stream? My network can push at least 10x what the new hard limit is and the quality is suffering from it. I suspect this has something to do with the imminent influx of Steam Link users and preventing complaints of latency issues on less-than-ideal network connections :(
