I have an i9 9900K CPU, and I have no issues with capturing using x264 using an E1S at 1600x1200 in RGB (for some reason RGB24 does not work for me over DVI from an OSSC, so I capture in RGB32 and truncate the empty alpha channel to RGB24). I capture using x264 lossless settings, use low compression (Ultrafast, I have not tried the slower modes), zero latency mode and RGB mode (E1S settings and x264 codec settings) to avoid any image degradation . My capture application is Virtualdub2 and the only change that I have done is to increase disk buffer size slightly (this may not even be necessary). I use two old Samsung HD204UI 5400rpm 2TB drives in RAID0 (Windows 10 software RAID) as a dedicated capture drive .
I did not bother taking note of exact CPU load, but I am pretty sure it was below 20% .
Have you tried OBS? I have been using it for recording and also trying some of that newfangled streaming stuff 🤣. But I think it could be a bit touchy or just not great with the Datapath card.
I was using Virtualdub back in 2012/2013 with the Avermedia Game Broadcaster HD. I remember tweaking x264vfw. VDub is certainly solid software. So many software choices these days.
I do not intend to livestream using the E1S, so I did not bother trying OBS with it . I might give it a shot, just to test it (will report back if I do).
IMHO, if livestreaming is the use case, the E1S quality and RGB capability are overkill anyway. Though, it would be nice if it could work for people with that use case, as the card is inexpensive, well made and has extensive input resolution/refresh rate support.
I just thought about something, are you trying to capture 60Hz content at 60fps or are you using the E1S to downconvert the framerate ?
Also, just to be clear, I am using a Virtualdub2, an updated fork of Virtualdub. Virtualdub itself has not seen an update since 2013 . I also used to use the original Virtualdub back in the day . Kudos to Avery Lee for starting that from scratch .
