Question / Help Low FPS on stream but High FPS In-game.

[xkamerz]

CPU: i7-4770k
Ram: 8gb ddr 1600
MB: Gigabyte Z87x-UD4H
GPU: GTX 295

I dont know why, but im trying to stream at 1920x1200 @30 Fps on Twitch, but it runs at 2-3 fps.
The point is the machine can handle it because ingame I have 60fps stable.

Can anyone have an idea why is this happening?

Oh before you ask, I have 10mg/s upload rate & 100mg/s download rate.

Post a log, otherwise it's just guessing work.
My initial thought though, you have a quad core. Meh.

But er post your log. You can access it in OBS > Settings > Open Log Folder.

 

[dodgepong]

Yes, we would need to see a log file.

Though your CPU should be fine. The i7-4770k is technically a quad core, but has hyperthreading, so it should be quite a bit faster than a normal quad core. And quad cores are fine for streaming, anyway.

 

[Krazy]

Your GPU is likely holding you back here. It's very underpowered for what OBS needs, unfortunately. I'm surprised you aren't noticing in game performance issues.

Anyway, you will almost certainly have to downscale to at least 720p with that GPU. Your CPU is more than enough, however, being a Haswell i7.

There it goes, just let you know i tried setting max fps to 30 and i had the same problem (60 in this log).

Are you sure it's just not you watching your own stream while streaming? Because the broadcast would look really bad in that scenario.

 

[dodgepong]

Well, the fact that you were streaming at 60fps in this log certainly didn't help. That's an absurdly high frame rate and resolution to be streaming at, and most people won't even be able to watch it smoothly due to how poorly Flash handles such high-framerate-high-resolution video. Furthermore, a majority of monitors are smaller than 1920x1200, so most people won't even be able to watch it in full resolution.

And yes, it does look like your GPU is the biggest bottleneck. The 2xx series of GPUs is notorious for having slow VRAM, which is why it takes so much extra time to encode. I recommend downscaling to 800p or less, and changing your frame rate back to 30, and see how that works. Beyond that, I recommend getting a better GPU...it's kind of sad seeing a very nice CPU paired with a very old, outdated GPU.

 

[xkamerz]

Thanks for the help, ill try it and post here the result to help other people having the same isue.

Just one question, i have a friend with a very worst GPU, didnt know wich one, he cant even play games as good as me, but his streams works fine running at 20-25 fps, this is pissing me off.

 

[dodgepong]

We'd have to see a log from him, too, to see the differences between your setups.

 

[Floatingthru]

The issue is that your GPU has really slow VRAM which kills OBS performance. You can get a modern GPU with faster GDDR5, but with lower overall performance yet it will make OBS work much better than your GPU.

 

[xkamerz]

Well, after your recommendations here is the results.

What do you think guys, cant it go better cos of the GPU?
Thanks you all for your help.

Yeah, the GPU is still choking. Maybe you can try downscaling even more (640x400) or just manually set an even lower resolution than that (~360p) but the GPU is absolutely killing your streaming abilities, here.
