Question / Help 1080p streaming lags

Hello OBS users.

I just got a brand-new computer with decent specs and felt like "Hey, maybe I can start streaming my games now!"
The games I am playing/streaming will mostly be HoN, but there might be some other high-end games mixed in.
My question is now: When I tried streaming 1080p, it seemed choppy both in OBS preview and on my twitch. In-game it seemed fine. I then tried 720p and everything went smooth!
Should I be able to stream 1080p?

i5-3570K CPU 3.40GHz

Well, you might want to stay at 720p until you got partnered with twitch - not every viewer has a decent connection to be able to watch a 1080p stream.

but - at all - you also might be able to stream at 1080p, just depends on game. For me - I'm able to stream things like D3, PoE, LoL and other stuff like this in 1080p. Other things are causing a too heavy load for my cpu (3500k). All you can do is try it yourself und try to find some working settings.

What settings are you using at the moment? Bitrates? Quality? Preset?

You should be able to stream some games at 1080p, others will use too much CPU to leave enough over for OBS to do the encoding. At "fast" preset, though? No. Use veryfast, faster at MOST if a game uses very little CPU.

It does if you keep the quality balance at 10 without the bit rate to make up for it, yes. For RTS games at 5000/5000, you probably want to go with quality balance 8 or 7, for FPS games and the alike you want to go with 6 or 5.

There's simply no way you can stream with fast though, it uses way too much CPU for your processor to handle it at 1920x1080.

Alright it already seems better with those options, and I don't really see any difference in the quality whatsoever. Thanks for the replies!

5000 bitrates aren't good. there will be many users who will have laggs due to less internetconnection on their side.

try 3500/3500
veryfast
quality 6 or7

quality 10 causes pixelations on fast movements, the lower bitrate is enough to have a decent stream and viewers and fast preset isn't useful at all if you don't have a beast of a machine.

Twitch doesn't recommend users to go with bitrate more than 3500. Otherwise it's just way too much for viewers and also for their VOD storage space.
