Presently I'm using Multiplatform OBS but intend to build a streaming PC at which point I would switch the original version (though any comments as to possible differences between versions would be helpful).
I've relied on the estimator (and presently face a bottleneck given my highly constrained Canadian bandwidth) in the past and have browsed the forums and notice quite a few 'guess and check' recommendations, but I am hoping to try and pin down a few principles to guide my purchasing decisions.
Number of Cores
There is a convention (I don't have a hard source, but this seems to get repeated a lot) that a given game will really only utilize two cores. Other posts in the forum have implied that additional cores will result in improved performance for OBS, and I was hoping to confirm this. That is, while going from, say, a four cores to six cores is not likely to result in any performance improvements from a gaming perspective, but may make a lot of sense for someone streaming on the same machine.
Requirements For Encoding
Clearly there are a lot of different options available to us. Ideally I'd like to find some way of determining the impact of changing certain parameters. For instance, taking a baseline of streaming 720p at 30fps at the default usage preset (I think this is fast?), would require [X]. Changing the resolution to, say 1080, would require an adjustment to [Y], or moving from fast to medium would require [Z].
The idea here is find something that would let me do one of two things. Presently, to find out how much I need to commit to streaming itself (that is, take my desired quality parameters as given, then treat the game as if I have a computer with whatever is left over), but perhaps in future to consider building or upgrading a smaller machine to act as a pure streaming computer.
Above all, I'm looking to try and go beyond just 'video encoding makes heavy demands on a computer' and trying to quantify them, and determining what makes the biggest impact.
Thanks in advance for your comments.
