great test! But if you acheve those results with 4k and 1080p 60Hz what can it be with a 1080p 15fps? (you're right, it's enough) Can it go up to 6 streams? Amazing..
Thinking that I can buy such card with 160$ when Matrox claimes for expensive cards with probably same results..
Knowledge is the best weapon we have )

If I'm not bother you, may you kind test how many videos 1080p you can encode? Of course you you have the modified drivers (I'm not asking you do change them). I suppose it's enough to open diffent stand alone OBS and run each one the same video (a sample video 1080p 15fps). You can create one scene and clone it to other istances. Thank you a lot for testing )

I tried encoding 4 things at once with FFMPEG and it's not possible. 3 work fine, but with the 4th I get an error "no cappable devices found". So there really is a limit of 3 encodes at once. But if you do need a 4th you could use software encoding or Quicksync if you have a recent Intel CPU

Interesting, thanks, have you tried with modified drivers or original ones?
