Stuttering at 4K60 with AverMedia Live Gamer Ultra 2.1 and Elgato 4K X
Hello! I've been going insane the past couple of days putting these two capture cards through their paces and coming up empty on how to fix the stuttering they each seem to have.
My input source is my gaming PC with a 3080, using one of the Display Port outputs on the card (converted to HDMI). I can't use passthrough because I use a surround sound setup, which neither card can passthrough. AverMedia claims it can passthrough 5.1, but I couldn't get that working anywhere.
Here's some recordings I made of both cards in OBS doing the same two things, playback of a stutter test video on YouTube followed by some generic Ori gameplay.
They're both recording at 4K60 with NVENC HEVC at VBR 30k-60k on an RTX 4060 laptop.

Here's that stutter test video if you want to see what it should look like:

What I've tried:
- Different resolutions/frame rates. This sometimes makes a difference, but not reliably.
- Different encoding settings. Almost never makes a difference.
- Different computers. I've tried with two separate 3080 machines and a 4060 laptop (whose express purpose is to do capture) and they all produce similar results.
- Using their native capture softwares (RECapture and 4K Gaming Utility). RECapture sometimes produced better results from the AverMedia. 4K Gaming Utility produced consistently worse results.
- Updating firmware/drivers/software.
I haven't really seen much mention of these cards having these issues, so I'm not sure if I'm doing something wrong or if this is just expected behavior.
And, yes, I am using the provided HDMI and USB-C cables for both cards and am getting the full USB bandwidth in every scenario.
