High end PC lagging in stream using OBS

[♥♥♥ Stain on Anime Poster]

Hi everyone!
While using OBS streaming Rust the live stream is lagging a LOT getting about 0-40 fps. I was thinking of using a secondary GPU to take all the streaming load but the only spare GPU I have is an AMD Radeon HD 4850 512mb witch might not even work because of its age.
Nvidia shadowplay streams pretty well but then restarts my PC after about one minute.
It would be very nice to get this issue fixed.
Thanks.

PC specs:
i7 8700k stock
Be Quiet! Dark Rock Pro 4
MSI z370 A PRO Motherboard
Geforce RTX 2080 FE
16 GB (2x8) Corsair Vengeance 3000mhz RAM
EVGA GQ 750W 80+ Gold PSU
500gb Samsung 860 SSD
2TB HDD

I have the latest drivers installed

I only use OBS to record but it records perfectly fine and I have a 1700x and a 1050 ti. Maybe it's your upload speed. What is your upload speed? and what settings are you streaming at?. Not sure how that works since I don't stream with OBS but if you're trying to stream 1080p video and don't have the bandwidth maybe that's the issue.

Probably an issue with OBS.

Also, you can't run 2 GPUs if they are not the same design, only crossfire can avoid that, but even then it still has its limit. It has to be the same GPU to work. (2080s can only SLI with 2080s)

This is only the the case with SLI however he can actually use them as independent processing cards. Without an SLI bridge. However you can't mismatch AMD with Nvidia that is a no no.

That's not entirely correct if DX12 is involved. But back on subject. Can you tell OBS which threads on your CPU to use? That may help.

Lets not get into Hybrid Hetrogenous computing it's still not used anywhere. Although Adobe now can leverage an IGPU for some tasks.

If it was me, I would suspect a power problem. A minute is about the time it takes for a psu to shut down when it is struggling with the load. Maybe a temperature problem. The psu is tier 3 - ok, but not great.

It might also be a driver problem. Some gamers have reported crashing with the latest drivers. One fix that seems to work in sniper elite 4 s to use dx11 and not dx12. So I would try rolling back a few driver releases. I have seen crashes with the new drivers in se4 and civ4col when moving the mouse quickly. But drivers wouldn't causea shutdown.

I would monitor pc activity with msiafterburner and hwinfo64. Try taking the sides of the case to rule out airflow issues.

I'd also suspect the FE gpu. Maybe try streaming at lower settings.

Thanks for all the replies guys!
All my componants in the PC are not thermal throddling during gaming and streaming.
CPU: Max 55 celcius
GPU: Max 73 celcius
I also tried streaming at lower resolutions and settings but it didnt change much.
My internet speed is super fast (telus fibre) but I am using a wireless internet dongle and not an ethernet cable.
My monitor is the DELL SG2417 (1440p, 165hz, Gsync)
For my PC shutting off after streaming with Shadowplay I'm not sure but it could be because I'm using a power adapter thing that converts 1 outlet thing into 6. The monitor, PC, LED lights, and charger for my school laptop are connected to that.
Could that be a problem?
And just one more question: Why would mixing an AMD card with an Nvidia card be a no no?

You probably just have the stream settings set way to high, what are they set to, including the encoding (best / fast / fastest etc)

So it seems you've got 3 ways to encode the video - NVENC, Intel QSV and software h.264. Did you try all the methods?

[Hare+Guu!]

Sounds like your cpu/gpu is throttling due to a faulty psu. GQ isn't an awful psu, but it's not impossible you have a dud. Cpu are generally not as demanding power wise compared to gpu, so you only experience the power failure with the gpu.

Thanks fo the replies!
I tried NVENC and h.264 but they are both the same story.
When I do it on the h.264 there is still lag even tho my CPU doesn't hit 100% usage in task manager.
All thermals are just fine.

Try Intel QSV aswell. Your iGPU is definitely capable of it.
