Question / Help HD60 Pro & OBS studio: near 100% encoding lag & stuttering issues

[Mooha]

85% of the time I try to stream on this PC I have to stop and restart and mess opening and closing OBS until it works correctly

Issues:
Near 100% skipped frames due to encoding lag. Same no matter if I use GPU or CPU down-scale.
HD60 Pro stutters & lag in OBS but not Game Capture HD.

Processor use (spread evenly across all cores/processors) never exceeds 50%, usually it sits at 30%. GPU use sits around 35%

It's a Dell R610 windows server 2016 box with a new GT 1030 GPU and dual Xeon X5570 processors. I have tired everything trying to figure out this thing isn't working.

This CPU is 8 years old and made for server usage. The GT 1030 is a low end GPU. The CPU performance is about the same as a state-of-the-art medium to high-end notebook CPU - not very high.
It may be that pci-express bus is a bottleneck here. Could you post a screenshot from the first page of GPU-Z? This gives a good estimate about how fast the GPU can be accessed, which is essential for OBS, even if there isn't any local game or window capture.

The thing I know it's 'old' but it does work, and it works well when I get lucky.

Any words anyone? Remember, this only happens in OBS...

Sounding more and more like this HD60 pro is just going to get returned...

It's more that this PC hardware should be retired. The HD60 pro is probably as much a the whole server, if you sell them separately.
I googled... a Dell R610 is a rackmount server. I hope you didn't fall for this: https://www.youtube.com/watch?v=9EyazseWtCk
It belongs into a rack. I assume it's louder than a vacuum cleaner. Its power demand in a year is as much as you paid for the hardware. How did you built the GT 1030 and the HD60 pro into the server? Riser cards? According to the video, the server doesn't have wide pci-e slots. If you really run it with Windows server 2016 - this software is more expensive than the whole hardware.
There is no relation between what you have to do and to invest to make all this run even at a basic level.
I would not invest even one more second to fix obscure performance problems with a system that was not meant to be used the way you try to do. It's wasted. It's bricolage.

Hi, no this server I bought for internal web server testing and personal cloud storage work back in 2015. It's paid for itself over so I am not worried about the cost of the server. It's actually not that loud as it's in a 19" rack with my other equipment. I also do all of my work with headphones and a professional noise gate due to how loud it is living near an airport. The GT 1030 was dropped in to the normal PCI 2.0 8x lane and is running fine regardless of what I throw at it. Temps's, GPU utilization %, and everything else is normal in afterburner. The riser card for the GPU was dremel'ed out by me which I have done to three other servers for work. The windows server 2016 software was given to me, so I actually have no clue how much it costs other than it's a free fully-fledged server key.

I'd like this intermittent software issue to go away as I know it's not a hardware issue. I ran a stream for many hours and can confirm that it's not hardware related, it's just it takes dicking with settings, closing OBS, opening Game Capture, restarting, and a lot of other screwed up stuff to make it work. I'll likely be building a new gaming PC in a year from now but in the meantime I just need my setup to work.
