Question / Help Unexplained drop in bitrate

I've been streaming fine at 1200kbps but all of a sudden my bitrate has dropped to between 300-500kbps for absolutely no reason. I have not changed any settings whatsoever. Could there be some sort of explanation for this besides my internet just being weird?

What do you mean? You mean your bit rate monitor on OBS shows 300-500?

If that's the case, that's not a bad thing...but you can try enabling CBR to prevent that and keep your bandwidth usage more constant.

No, CBR, not CFR. CBR = constant bit rate, CFR = constant frame rate. You want to enable CBR, in your Encoding settings.

Oh right, sorry. I enabled that and now it's between 0-375 kbps. I have no clue why.Could twitch just be fucking up?
