So here's the optimal settings I think I'm going with.
1750/1750. 2k/2k gets stutter sometimes, and 1500/1500 the quality is slightly noticeable lower. I'm going with 45fps, because that's a decent step up from 30fps, and since my upload is good, THATS where I can take advantage of a low end computer with a high end upload (or bitrate quality, but bitrate quality isn't as noticeable as high fps i think). Based on what I've learned that Bitrate & FPS = Image Quality
Also, since my GPU is relatively high end (gtx460, which is super power for 720 starcraft), I can 'artificially' increase my stream quality by raising my graphics settings. So my stream might look prettier than the standard i5 or i7 on low or a much higher bitrate because of better in-game graphics settings.
There's a couple dropped bframes dropped, not many at all. I think maybe lowering it could reduce it to zero, not sure, I've seen dropped frames at 1500/1500 too though.
Anyways, thanks for helping me set up a very nice looking stream on a not-so-nice computer, and showing me that OBS>Everything else out there. I think OBS has a lot of nice options on it that make it great, and you Jim, have given more feedback than any other stream guy out there (this thread exists in the ffsplit and xsplit forums too lol).
Here's a video of the stream settings just being perfect. And a pretty kick-ass game to boot, it's a ZvP and the game actually ends up in a tie, except it isn't a countdown situation. We both killed eachother's last building at the exact same second and so the system ruled it a tie. Something neither of us had ever seen before, quick shocking ending actually.
