Question / Help CFR and Delay

[Bensam123]

So I'm not sure if this is from CFR, but it seems as though some users end up further behind the stream then others. This seems to only really have started happening after I enabled CFR. Does CFR prevent frames from dropping so users with slower computers end up further behind? It seems like it also happened on my laptop, which is constantly pegged due to running a few things on it. Normally with CFR off it keeps up with the stream even if it drops frames here and there, but with it on it's steady video... it just ended up like 30 seconds behind my stream.

Anyone notice similar?

i give you the answer ... but please dont laugh

INTERNET and DELAY if twitch needs to buffer and you got the known lagg lately you fall even further behind!

 

[Lain]

Hm, added stream delay usually only happens if you're having connection issues and you're teetering on the frame drop threshold a lot. You getting red/yellow on the indicator at all?

CFR shouldn't be causing it at all. In fact it's pretty much always technically on by default now.

 

[Bensam123]

I do occasionally get the rainbow colors, but they don't ever last long enough to drop frames.

 

[Lain]

Hm, I think in this case reducing the frame drop threshold may be useful to prevent buffering. I may add an option to adjust frame drop threshold in the future.

However, I would recommend seeing if lowering your bitrate helps at all first. You might also get better results with minimize network impact due to the fact that it will split up packets to be less bursty, but I'm not network-knowledgeable enough to say if that would help at all for certain (that's r1ch's department)

 

[Bensam123]

I use miniminze network impact and automatic low latency mode. I have been using these settings (except for CFR and a higher audio bit rate) for close to six months now though and it's only recently become a problem. This also seems to correlate with Twitch's tomfoolery.
