Ok, I have updated both the drivers and my motherboard Bios to the most current versions, even the beta version.
Now I do have stable 60 fps, but only without NDI or Teleport Encoding enabled, or if I only have one stream encoder running.
If I use my GTX 1060 3GB as my main GPU to run OBS, but set all encoders to the Intel card, everything is smooth and works fine. I can run NDI + Stream to 4 different RMTP encodes no issue at all. Running just the Sparkle a380 is when I run into issues. 1 or 2 encodes + OBS (WITHOUT NDI or Teleport) work just fine, but as soon as I add NDI or a more platforms I run into issues.
Here is JUST NDI or Teleport enabled:
As you can see it's having trouble even with just adding multiple platforms.
But this is actually an improvement as I never saw even close to 60 FPS previously.
My power supply is a RaidMax 750w Gold PSU. I was recently using it in a different system, with an 5700x + 2070... It had zero issues on that system. So the PSU shouldn't be an issue here at all.
This PC is dedicated for streaming. I do not use it to game or do anything else. It's entire job is to run OBS and streaming related programs.
I have tested this with multiple OBS profiles and Scene Collections. Things are fine until I turn on NDI output or Teleport Output.... Or if I stream to multiple outputs with the MultiRMPT OBS plugin.
With the GTX 1060 as the main card in the system and the intel card as an encoder OBS runs perfectly and has no issues with my setup.
Ok, Update: I installed a fresh version of Windows 11 - moved all my stream files, OBS, Plugins Etc... over to the new FRESH install of windows on a brand new M.2 Drive. Installed ALL the latest drivers.
The issue still persists.
OBS still cannot maintain 60 FPS with NDI running.
Hopefully this is enough for you to pass this over the technicians so they can figure out why the card is having issues with OBS.
Ok, so there's a couple issue here.
#1 if you think dropping below 60 FPS with only 3 display capture sources running while streaming is "not reproducing the issue" then I don't think you understand the actual issue here. Your own video highlights that there is in fact an issue:
If OBS was running normally, you would NOT see this happening. Render lag with so little going on almost 8% dropped frames in less than 3 mins of streaming is A LOT and shows that the GPU is struggling. The fact that it cannot keep a stable 60fps locked while you just move the stats window around speaks volumes to the issue at hand.
Maybe you are not as experienced with OBS and that's fine. I have almost a decade of experience with OBS and running it on low end hardware. My GTX 1060 3GB doesn't even come close to this kind of negative performance running OBS with a much more complicated scene, cameras, alerts, and even "3rd party plugins."
#2 This brings me to the second issue: so called "3rd party plugins" - OBS is a third party. It's not owned by intel. Plugins associated with OBS are in fact, just as distant from intel as OBS is. Are you suggesting an Open Source project is supported by intel, but plugins are not?
So do we have to wait for OBS to have native teleport or NDI... What about the Multi-RMTP plugin? All that is doing is sending the stream to multiple platforms at once and that also causes the issue (as I in great detail have explained in my previous posts).
It sure seems like you are just trying to pass the buck here and clean your hands of the situation, when clearly in your own video you can see the performance issues. By your own evidence you have recreated the issues and claim nothing is wrong.
OBS should never drop below the set framerate, especially given so little is going on in your scenes here. Even when dropping frames due to a quick spike in usages because of heavy alerts or a sudden spike in CPU usage, you should never see OBS drop below 60fps down to 59.02. This is NOT normal behavior, and is direct evidence that the drivers are not dealing with the Directx11 drawing of OBS itself well.
Please look deeper at this issue and have a higher level tech look at this situation. My GPU from 2016 with 3GB is out performing this a380 in just basic OBS tasks at this point. Running a single plugin without even going live is a good test for seeing the issue. The fact that you didn't go beyond the basic tests to see there might be an issue is absurd to me. In reality people are going to use "3rd party plugins" and when they work just fine on 8 year old GPUs, why would anyone bother to assume something is wrong with the plugin when ONLY arc cards are suffering from this issue?
I already confirmed that OBS runs well enough without the plugins. Why even bother testing anything if you are just going to ignore the real issue. Putting any sort of real load on OBS is causing dropped frames. My clients who are streamers, and myself, who bought this card are having to give up an extra PCI-e Slot to run a second GPU because of this situation, which means we have to give up a device slot that would allow for greater expansion on our streams (USB ports, Capture Cards, etc...). Now we have to trade that expandability for stability on our streaming PCs because your GPU is less stable.
Please don't pass the buck here, you are one of the leading companies for computing power and you are trying to break into this new market for GPUs. Ignoring my voice here will do you more harm than good long term in this space. If you can figure this out, many streamers would quickly invest in an arc card for their stream PC - which is not a small market, and will soon be much bigger when Twitch launches AV1 support beyond Nvidia cards.
As a streamer, who works with other streamers, I am advocating for a much larger group of people when I say this: Please look into this issue!
