Just wanted to take some time to let you know, in case you missed it elsewhere; I'm without broadband service right now, and this may continue into next month. There are bigger things on my plate, and I can't keep it up. As such, I'll be unable to stream for the near future. I'm on a YarrHarr Connection right now, but it's taken me several days to find one I can use, and this one has been spotty at best... 2 days between my last period of connectivity. :/
Itnet, roll back to the previous build of Livestream. Their latest build is an audio/video desynching trainwreck. I don't have the URLs saved on this compy, but the new build was terrible for my connectivity, speed, and staying synched... somewhere on the site, they have the version history, which you can reinstall once you uninstall the new one.
As for keeping a decent stream speed when running demanding programs, the first thing I do is close all extraneous programs... everything non-vital that uses over 10,000 k of RAM. I lower my monitor resolution a few steps too, which has been a significant help when using Screen Capture mode (the program has to process less visual input when cropping each frame, and it's made the difference between unwatchably stuttery, and high-speed high-def streaming). Another workaround is to use the Direct/Game capture mode, which works with any game that uses DirectX video. It rips video directly from the software without the extra screen capture step, and tends to be significantly faster, have less glitches, and look better too. Downside is it only works with DirectX programs, and sometimes doesn't actually stream when it says it does; that's why I always check with the audience to make sure we're live. On occasions, I turn the audio quality to Mono instead of Stereo, and lower the expected framerate in the options, which helps a bit too.
Sorry for my brevity. I'll try to keep posted for as long as my net holds out. Take care, and when I'm through this, I promise many exciting streams to come! We've got more Lodoss War, the Owlboy Demo, Amnesia: Justine, and Arvoesine (a platformer with Roman Legionaries) to come!
