Question / Help Assassin's Creed Odyssey stream/recording stuttering while game runs perfectly smooth

[harpooneer]

Hi guys,

my machine:
CPU: Intel i7-7700K@4,4GHz
GPU: GTX1080 (latest driver)
Mem: 16GB DDR4-2133
Windows 10 1809
OBS 22.0.2

While I'm playing Assassin's Creed Odyssey the game runs perfectly smooth on Ultra Settings (Full HD, fullscreen) with 50fps on the gaming monitor. But every recording or streaming is constantly stuttering like hell: https://youtu.be/xdw5D3pYCME

Ingame graphics settings: V-Sync=on, FPS-Limit=50FPS

Streams or recordings of any other game (BF1 for instance) are running smooth like a charm: https://youtu.be/7esM6HkZkCQ

It's only Assassin's Creed Odyssey... *grml*

Can anybody help?

That's the exact same game i'm trying to stream having the exact problem except much worse stuttering than yours and i'm sitting on a I78700K and 1080 Ti.

Thanks for your feedback, Kihlo7. I'm glad to hear that I am not alone with that problem. I wonder why people can stream ACOD flawless with even less powerful equipment (8700K, GTX 1070): https://youtu.be/784Mh6l8vBs
Do they use a capture card with an second PC just for streaming?

That's a good question i have actually had a conversation about this with friends off and on over the last few years i see a lot of streamers with hardware a generation or more behind what i have or friends have yet they seem to have flawless streaming. I don't profess to know anything about streaming but from what i have gathered from many different sources the hardware we both have should have absolutely no problem streaming this game. I had originally thought my internet connection could be my issue but i'm getting 160+ down 12 up so i don't believe that's the issue but again i know nothing about streaming. I actually posted on this forum the same day you did but my post was deleted for some reason i wish i knew why. I don't want to hijack your thread but i'm gonna post my specs as well since we both seem to have the same problem with the same game.

17:24:38.731: Output 'simple_stream': Number of lagged frames due to rendering lag/stalls: 7221 (49.1%)

You are overloading your GPU. OBS needs GPU resources to render frames, and it isn't getting them rendered fast enough half the time.

If the game runs great, but the stream doesn't, you need to cap the framerate in your game to keep GPU utilization by the game low enough that OBS can render frames without any lines like the above appearing in the log.

If that doesn't help you may need to reduce canvas size, reduce frame rate, reduce graphical fidelity options in the game, or some combination of these until there are no more entries in the log about rendering lag/stalls.

Okay Narcogen, that's true in Kihlo7's case. If you look at my log, there is only 1 frame lost and my GPU ist only at 75% max load because of my framerate limit. So there is enough headroom for my GPU...

Can you please take a look at my logfile too? Any suspicious entries?

I didn't even consider the problem may be with the actual game settings and that should have been obvious to me but alas, it wasn't.
I really appreciate it thank you. Sorry Narcogen i feel bad i got mine answered before you when it's your thread sorry about that.

It was me who startedt the thread! ;-) And it's no problem you found your answer. I still hope there is an answer for my problem too.

Anybody? Any ideas?

I don't see rendering or encoding lag in the OP's logfile, but there is no really good reason to use CBR and a 6000 bitrate with NVENC; that's going to give you poor quality and use more disk space than required. For recording and NVENC you should use CQP rate control.

Oh lmao sorry i used the wrong name woops! and yeah didn't help turning down settings in game for me so no idea what's wrong =(
